Community-based Integrated Watershed Management A community-based approach to integrated rural development uses watershed management as an entry point Overview
Rainfed agriculture in arid and semiarid tropics is complex, diverse, risk prone and characterized by low levels of productivity and low input use efficiency. Water scarcity and land degradation are the major concerns for agricultural development and poor water use efficiency in dry lands. Changing climatic situation in recent years put extraordinary challenges especially in rainfed areas and is highly vulnerable for agriculture production. Current yield levels in semi arid tropics are 2-5 folds less than the potential yield, indicating e scope for harnessing untapped potential. ICRISAT demonstrated an innovative consortium model for community development and poverty alleviation in which integrated watershed development programs are implemented as entry points.

Village Level Studies ICRISAT’s unique contribution to the global knowledge base on better understanding of constraints and pathways to agricultural development and poverty alleviation in the dryland tropics Overview
The innovation
The ICRISAT Village Level Studies (VLS) started in 1975 by surveying panel households in six villages in semiarid tropics (SAT) of Andhra Pradesh and Maharashtra states of India. The studies were initiated to enhance availability of reliable household, individual members, field-specific high frequency, and time-series and spatial data to better understand farming systems and socioeconomic constraints of SAT farmers. Director RP-MIP, Cynthia Bantilan (in white) and team members discuss collective action by women with farmers in Kanzara Village, Maharashtra state.
v The Economics Program (now known as RP- MIP) gradually expanded survey scope from farming systems to technology adoption and impacts, poverty analysis, livelihoods, risks and vulnerability, and coping mechanisms. v The ICRISAT VLS data bank is equivalent to a biological “gene bank”. It provides a “field laboratory” to undertake multi-disciplinary research on farming systems on a variety of topics by integrating biological, technical, social and economic approaches. v ICRISAT VLS provides a unique set of high frequency longitudinal (since 1975) panel data of farm households that are International Public Goods (IPGs).
Objectives of VLS
ICRISAT team collecting information on social networks and relationships in village Aurepalle.
v To provide socio-economic field laboratory for research, teaching, training and outreach v To track changes in the farm activities, farming systems, socioeconomic and biophysical constraints and livelihood options of the rural poor v To understand response of rural women and men to changing markets, policies and technologies v To understand women and men farmers’ response to agroclimatic variability, and their coping mechanisms against risks and vulnerabilities v To understand dynamics of rural transformation, poverty, and drivers of change v To provide feedback for designing policy interventions, setting research priorities, and refining technologies Food and water scarcity are common plights in poor villages of India.
The impact
v VLS have attracted many scholars globally for path-breaking research in rural economy. VLS data sets are considered as International Public Goods (IPG), and rank among the most valuable contributions of the CGIAR to the global communities. v The VLS data reveal many valuable facts of the farming systems and livelihoods, and was termed as the ‘goose that lays golden eggs’ in the World Development Reports of the World Bank (2008). v Over 150 research papers and over 40 doctoral dissertations have already been completed using the VLS dataset, resulting in over 10,000 citations of the VLS data (Google Scholar, June 2011).
Analyzing feedback of discussions held with Zimbabwe farmers.
VLS development stages: Past, present and future
v 1975-85: Intensive data collection started in 6 villages of SAT India with regular and several special purpose surveys. v 1981/82 onwards: VLS started in 6 villages of Burkina Faso and 4 villages in Niger. v 2001-08: Expanded survey work in India through linking with the World Bank, ODI and National Agricultural Technology Project of ICAR. v 2009 onwards: VLS activities expanded from 6 to 42 villages in South Asia (5 states in SAT India, 3 states in East India, and 12 districts of Bangladesh), under the project “Village Dynamics Studies in South Asia” funded by the Bill & Melinda Gates Foundation.

Aflatoxin Testing Kit An inexpensive innovation that helps to identify aflatoxin-free grains so as to meet international market standards thereby ensuring higher returns for farmers and safer products for consumers Overview
v ICRISAT scientists devised a simple and affordable test kit using in-house-developed polyclonal and monoclonal antibodies.
Aflatoxins, produced by Aspergillus flavus and A. parasiticus, pose a major threat to food safety. Many agricultural commodities including groundnut (peanut), are contaminated by aflatoxins each year, affecting trade, human and livestock health.
v The test uses a competitive enzymelinked immunosorbent assay (cELISA) to rapidly detect the presence of aflatoxin. v Results obtained using cELISA are comparable with those of the highly sensitive HPLC. Also, cELISA requires minimum laboratory facilities, and chemicals are locally available in developing countries. v The kit has drastically reduced the cost of testing agricultural commodities for aflatoxin.

The impact
Magnification of the fungus.
Components of the aflatoxin testing kit and some susceptible food material.
Consumption of aflatoxins by humans can lead to acute hepatitis, immunity suppression and hepatocellular carcinoma. Hence, several countries reject imports of agricultural products that exceed certain levels of aflatoxin, costing developing-country farmers millions of dollars each year in lost sales.
v The cELISA test provided a unique opportunity for ICRISAT and its partners to monitor food and feed commodity value chains and identify entry points for aflatoxin contamination. v ICRISAT helped to set up aflatoxinmonitoring laboratories in India, Mozambique, Kenya, Malawi and Mali. Local personnel were trained to manage the facility. v The 1970s saw Malawi’s status as a major groundnut exporter eroded due to aflatoxin outbreaks. v The National Smallholder Farmers’ Association of Malawi (NASFAM) has successfully used the cELISA technology in conjunction with HPLC as part of a broader effort to regain its once lucrative European export market during the past 5 years.
The innovation v The key lies in efficiently and inexpensively detecting aflatoxin, the invisible killer. v Developed countries use expensive chromatography based technologies in sophisticated laboratories for routine quantitative estimation. v This high cost of aflatoxin estimation constrains the development of integrated aflatoxin management technologies.
Technology transfer. The benefits of detecting aflatoxin-infected grain will eventually impact on the livelihoods of poor farmers.

Drought-Tolerant Groundnuts An ICRISAT groundnut variety resists drought and diseases, has good fodder quality and replaces varieties grown for more than 60 years, bringing hope to millions of poor farmers Overview
Anantapur is a drought-prone district in the rain shadow area of Andhra Pradesh, India. Despite frequent droughts and crop failures, over 70% of the cultivated area in the district (~1.0 million ha) is sown to groundnut each year (Figure 1). Smallholdings (<3.0 ha) dominate 60% of the district, the largest groundnut growing area in the world. Soils are light textured, gravelly, shallow Alfisols, low in nutrients. Rainfall is erratic with prolonged dry spells of 45– 50 days, Annual rainfall is 522 mm. Groundnut yield in the district is highly variable (Figure 2) and determined by rainfall. Nevertheless, groundnut can survive long dry spells and is a valuable source of fodder during dry years.
The former Chief Minister of Andhra Pradesh, late Dr YS Rajasekhara Reddy hands over the ICGV 91114 seeds to Anantapur farmers on 1 June 2006. On his side is Mr N Raghuveera Reddy, Agriculture Minister.
❖❖ Adoption of ICGV 91114 had a pod yield advantage of 23% with 30% reduction in yield variability and 36% higher net income compared to TMV 2. ❖❖ It is estimated that the annual value of benefits in the district would cross US$500 million, assuming 35% adoption by 2020-21. ❖❖ In spite of severe drought conditions in the past 4-5 years, ICGV 91114 occupied 25,000 ha out of the 800,000 ha under groundnut in the district in 2010. ❖❖ The possible economic benefits of its adoption demonstrate the impact of breeding groundnut for drought tolerance.
The innovation
Distribution of the seed of ICGV 91114 released by the late Chief Minister of Andhra Pradesh, Dr YS Rajashekar Reddy and DG, ICRISAT, Dr Willam Dar Groundnut variety ICGV 91114 was bred and developed at ICRISAT headquarters, India from a cross of ICGV 86055 x ICGV 86533, and has the following features:
Fig 1. Share (% of the total cropped area) of different crops on sample farms in Anantapur district, Andhra Pradesh, India, 2008–09.
❖❖ High yielding ❖❖ Matures in 90-95 days in the kharif (rainy season) ❖❖ Tolerant to mid-season and end-of-season drought ❖❖ Average shelling turnover of 75% ❖❖ Oil content of 48%, protein content of 27% ❖❖ Better digestibility and palatability of haulms (dry fodder).
Fig 2. Area, production and yield of groundnut over the years in Anantapur district during 1966–67 to 2007–08.
ICGV 91114 was released by the Andhra Pradesh State Seed Sub-Committee in 2006 and was notified in The Gazette of India in July 2007. It was subsequently released as Devi in Orissa. Our collaborator in Anantapur district, Accion Fraterna, named it Anantha Jyothi.
The impact
❖❖ ICGV 91114 meets all farmer preferences of high pod and haulm yields, high shelling turnover, good seed size, and resistance to drought and diseases, making it the most popular dual-purpose groundnut cultivated in India today. Groundnut crop on gravelly, shallow Alfisols.
Although the state released improved groundnut varieties during the last 20 years, old varieties such as TMV 2 (80% of the area, released in 1940), JL 24 (15–20% of the area, released in 1978) and Pollachi Red (a landrace) continued to dominate, as new varieties fell short of farmers’ expectations.

Early Maturing Chickpea Early maturing chickpea, with improved fusarium wilt resistance, high yield potential and good seed quality, has greatly increased crop area and productivity in short-season environments Overview
v Andhra Pradesh was once considered to be a low yielding state for chickpea because of its warm, short-season environment, but it now has the highest yield levels in India.
Chickpea is currently grown on ~12 million ha in >50 countries under a wide range of environments and cropping systems.
Partners
In about two-thirds of chickpea growing areas, the crop growing season is short (90-120 days) because of terminal drought or heat stresses.

The impact
v Early maturing cultivars avoid terminal drought and heat stress. v Adoption of early-maturing chickpea cultivars has led to an increase in area and productivity in short-season environments such as Myanmar and Andhra Pradesh state of India. v There has been >2-fold increase in both area (129,000 to 282,000 ha) and productivity (651 to 1411 kg ha-1), and a 4.7-fold increase in production (84,000 to 398,000 tons) of chickpea in Myanmar during 2000-09. Four early-maturing chickpea cultivars (Yezin 3, 4, 5 and 6) developed from the breeding material supplied by ICRISAT covered over 80% of the total chickpea area. v The adoption of early-maturing chickpea cultivars has brought a chickpea revolution in Andhra Pradesh (AP) state in India. v In AP, chickpea production increased 9-fold (95,000 to 884,000 tons) during 2000â&#x20AC;&#x201C;09 as a result of a 5-fold increase in area (102,000 to 602,000 ha) and a 2.4-fold increase in yield levels (583 to 1407 kg ha-1). v Over 80% of the chickpea area in Andhra Pradesh is now cultivated with the short-duration improved varieties JG 11 and KAK 2, which were developed through a partnership between ICRISAT and the Indian national agricultural research system.
Bountiful chickpea harvests spell much improved livelihoods for farmers.

Pigeonpea in Eastern and Southern Africa ICRISAT varieties resist wilt, have high yields and large seeds, and are widely grown in Kenya, Malawi, Mozambique Tanzania and Uganda, increasing farmers’ incomes by up to 80% Overview
market access, and helped to increase local producer prices by 20–25% in Nairobi and Mombasa after linking producers to wholesalers. v Most importantly, introduction of mediumduration varieties (ICEAPs 00554 and 00557) provides for two crops a year This attribute of early maturity allowed spreading of pigeonpea to non-traditional areas in Kenya, Malawi, Mozambique and Tanzania. v Enterprising women farmers lead demonstration of pigeonpea technology and proudly call it “our dryland white coffee”, as well as “our beef”, alluding to its high protein content.
ICRISAT pigeonpea varieties resist wilt, have high yields and large seeds, and are widely grown in eastern and southern Africa (ESA), increasing farmers’ incomes by up to 80%. Until recently, farmers were unable to fully exploit the potential because local varieties were low-yielding, latematuring and susceptible to pests and diseases. Small-seeded varieties failed to meet market requirements; market linkages were underdeveloped; and farmers could not access seed of improved varieties. Director General Dar and Director ESA, Said Silim, admire the wiltresistant pigeonpea in Babati district of Tanzania.
Partners
v Recognizing the demand for improved seeds, local agro-dealers (called Agrovets) contract farmers to multiply high quality seeds, supported by local extension systems for training and farmer organization. v The commercial produce is marketed through producer marketing groups (PMGs). This collective action enables smallholder farmers to sell quality grain at higher prices.
The impact Dr Phillemon Mushi of SARI, Arusha, admires the heavy pigeonpea podding at a village in Karatu, Tanzania.
Scientist Sabine Homann (right) discussed pigeonpea with a member of the national system and a farmer.
These factors deprived farmers of the benefits of a sizable export market. India alone imports over 254,000 tons of pigeonpea per year, but Africa supplied less than 5% of this demand. Similar high-value niche markets exist in Europe and the Americas. Domestic demand for pigeonpea has grown substantially over the last few years, increasing wholesale prices.
The innovation
v ICRISAT and partners developed high yielding, slightly early- , cream colored, large seeded and fusarium wilt resistant varieties. v Availability of improved varieties along with institutional innovations enabled farmers to reduce the cost of product marketing, spurring commercialization of the crop.
v Commercialization of pigeonpea enables farmers to buy valuable assets ranging from mobile phones to land, houses and livestock. v Farmers have invested in small ruminants, milking cows and bullocks, helping them diversify and expand their income sources. v Increased income enables increased school enrollment of children. v In Babati district – famous for high quality pigeonpea – adoption of improved varieties has reached 60%, and pigeonpea alone contributes more than 50% of the cash incomes of smallholders. v ICRISAT-developed varieties dominate the fields. ICRISAT efforts have resulted in expansion of area under pigeonpea in the last 10 years from 0.45 m ha to 0.82 m ha in ESA. Pigeonpea consumption has increased as the bean crop has succumbed to pests and the changing weather patterns that the hardy pigeonpea can withstand. v Maize has traditionally been the main crop, but fails in three out of five years. Families now rely on pigeonpea, and have also realized the potential of fresh vegetable pigeonpea in the domestic market. v PMGs facilitated community seed production, local distribution and

ICRISAT’s collaboration for breeding with NARES in ESA resulted in release of 21 varieties in Malawi (6), Kenya (5), Mozambique (5), Tanzania (3) and Uganda (2). Strategic partnerships between NARS, commercial seed companies, input suppliers and farmer associations improved access to and marketing of seed. Private seed companies are now investing in production of commercial seed, selling to farmers through agro-dealers.

Pigeonpea Genome Pigeonpea is the first ‘orphan crop’, the first ‘non-industrial crop’ and the second food legume with a completed genome sequence Overview
• It will also be useful in identifying germplasm lines or advanced breeding lines with a broader genetic base for future breeding programs. • Modern genetics and breeding approaches such as genotyping by sequencing, markerassisted recurrent selection and genomic selection will improve the efficiency of pigeonpea breeding.
Pigeonpea is an important crop in Asia, Africa, and Central and South America, grown on nearly 5 million hectares worldwide. Despite its importance for food security in the world’s poorest regions, it has been under-researched in the past.
Scientists, technicians and field helpers apply the benefits genome sequence information for crop improvement.
Principal Scientist Rajeev Varshney setting up a genomics experiment.
Rapid advances in genetic improvement of pigeonpea have been constrained by a lack of genomic resources coupled with low genetic diversity in the primary gene pool. Pigeonpea was neglected until 2005, when intensive efforts by ICRISAT, the CGIAR Generation Challenge Programme, the US National Science Foundation, the Indian Council for Agricultural Research (ICAR) and several other programs led to the development of significant genomic resources.
• This technology was used to generate 237.2 Giga base pair of sequence, which, along with Sanger-based Bacterial Artificial Chromosome- end sequences and a genetic map, was assembled into scaffolds representing about 73% (605.78 Mega base pair) of the pigeonpea genome. • Genome analysis led to the identification of 48,680 pigeonpea genes. A few hundred of these are unique to the crop and relate to drought tolerance, an important trait that can be transferred to other legume crops. • The research identified 309,052 simple sequence repeats (SSRs), and 23,410 SSR primers were designed. • Similarly, after aligning the transcript sequences from 12 genotypes, a total of 28,104 novel single nucleotide polymorphisms (SNPs) were identified. • The completion of the pigeonpea genome has made a significant contribution to the genomic resources available for pigeonpea.
The impact
• The availability of a genome sequence opens up new avenues for pigeonpea improvement. • The genome sequence will help harness pigeonpea’s genetic diversity by identifying molecular markers and genes for targeted traits, and will allow researchers to develop superior varieties and parental lines of hybrids.

Guinea-race sorghum hybrids Sharing the benefits of hybrid vigor with West African farmers, while retaining the adaptation and quality traits of local germplasm Overview
accessions that give the highest heterosis in crosses with a West African tester came from Cameroon, China and Zimbabwe. v Farmer seed producer organizations are empowered to produce hybrid seed through ’learning by doing’, with training and technical support from IER and ICRISAT v Emerging seed companies have bought and marketed all the hybrid seed that has been available every year since 2009, when large scale production began v Sorghum is changing from a subsistence crop to an increasingly important source of income for farmers.
Sorghum varieties of the Guinearace combine high grain quality with excellent adaptation for major parts of the Sudanian zone of West and Central Africa. Yes, despite their exceptional yield stability, yield levels rarely exceed 2 t ha-1 in farmers’ fields. In 1999, ICRISAT and partners started unlocking the genetic potential of these sorghums to enhance the productivity of this staple crop.

Institut d’Economie Rurale (IER) program, and guinea-race accessions of worldwide origin from the ICRISAT genebank in India v First experimental hybrids produced in 2004 on new female parents of both inter-racial and guinea-race backgrounds v Regional testing of new sorghum hybrids was conducted in collaboration with the national research programs in Mali, Nigeria, Senegal and Ghana. v The first four sorghum hybrids with Guinea-race parentage were released in Mali in 2008.
The impact
v Extensive on-farm testing of the new guinea-race hybrids enabled thorough comparison of yields against the well-adapted control variety, Tieble, under farmer-managed conditions. v Average yield of all eight developed hybrids showed 28% superiority over Tieble. v Two of the released hybrids, Fadda and Sewa, produced 450 kg ha-1 than Tieble, displaying 46% yield superiority across all environments. v Hybrid yield superiorities expressed across the entire range of productivity conditions and across the full range of soil fertility conditions and sowing dates. v Initial results show that high heterosis (hybrid superiority) can be obtained when parents from humid West Africa, East Africa, southern Africa and even Asia are crossed onto a West African tester. The
Farmers Days see a good response from discerning farmers.
The innovation
v Researchers developed hybrids based on well-adapted guinea-race parents that grow from Senegal across to Nigeria and Cameroon in West and Central Africa v A major task was to develop the first guinea-race female parents based on the cytoplasmic nuclear male-sterility (CMS) system v Genetic materials used included local varieties from Mali, inter-racial (GuineaCaudatum) breeding lines from the Malian

Extra-early Pearl Millet Hybrids Developed via inter-institutional collaboration, integrating marker-assisted, participatory and conventional breeding methods, extra-early pearl millet hybrid HHB 67 Improved has enhanced downy-mildew resistance and yield The Impact
HHB 67 was rapidly adopted by farmers and the seed industry.
Principal Scientist CT Hash (in hat) identifying an off-type plant in a field of good pearl millet.
The Innovation
❖❖ HHB 67 was developed at CCSHAU by crossing inbred restorer line H 77/833-2 (bred at CCSHAU) onto an exceptionally early seed parent bred by ICRISAT from materials introduced from Kansas State University, USA), reflecting inter-institutional research efforts. ❖❖ Several DM-resistant versions of the seed parent were developed at ICRISAT using conventional pedigree and backcross breeding. ❖❖ Efforts involving ICRISAT and Advanced Research Institutes in the UK had identified two DM resistance QTLs in H 77/833-2. Two more were added using marker-assisted backcrossing (Figure 1) to develop more DM-resistant male parents. ❖❖ HHB 67 Improved, produced by crossing improved DMresistant seed parent 843-22A with improved restorer parent H 77/833-2-202, was free of DM incidence vs. 98% incidence in HHB 67 under high disease pressure (Figure 2). ❖❖ Over 3 years in national trials, HHB 67 Improved gave 1992 kg ha-1 grain yield and 4.5 t ha-1 stover yield (about 10% more than HHB 67). It was released in 2005 by authorities in India, and was the first public-bred field crop marker-assisted breeding product to reach farmers’ fields in India.

Large-scale adoption of hybrids in India has contributed to 73% increase in pearl millet productivity during the last 25 years. However, the drier and most drought-prone arid parts of Rajasthan, Haryana and Gujarat receiving <400 mm of seasonal rainfall, benefitted little from hybrid technology due to lack of adapted hybrids, with early maturity being one of the essential requirements. An extra early-maturing hybrid, HHB 67 (matures in 65 days) developed on an ICRISAT-bred malesterile lineby CCS Haryana Agricultural University (CCSHAU) was released in 1990, and was rapidly adopted on by farmers in Haryana and Rajasthan.
❖❖ In 2002 (12 years after its release), HHB 67 was cultivated on about 774,000 ha in Haryana and Rajasthan. Superior performing HHB 67 Improved spread to 875,000 ha by 2011 (6 years after its release). ❖❖ Net additional benefits to the farming community from cultivation of HHB 67 Improved over the local varieties in Rajasthan and over HHB 67 in Haryana in 2011 alone reached Rs 675 million (US$13.5 million). ❖❖ Seed production of HHB 67 Improved gave a net income of US$6.4 million in 2011 alone to the smallholder seed producers in Andhra Pradesh and Gujarat. It also generated at least 900,000 person days of employment (45% for women). ❖❖ HHB 67 Improved helped stabilize

Sweet Sorghum A smart, multipurpose (food, feed, fodder, fiber and fuel) crop adapted to drought and climate change provides higher incomes for farmers Overview
Sweet sorghum is similar to grain sorghum but accumulates sweet juice in its stalk. Traditionally used as livestock fodder, the stalks can now be crushed to extract juice as raw material for ethanol production. Because of its short growing period, high biomass and bio-product potential, tolerance to drought, water-logging, saline and acidic soils, low water requirement and greater income opportunities, sweet sorghum is the preferred crop for cultivation on dry lands in the semiarid tropics. Sweet sorghum is recognized as an alternate feedstock for bioethanol production by the Government of India (National Biofuel Policy, December 2009). The sweet sorghum ethanol value chain shows a positive net energy balance of 7.5 and a reduction of greenhouse gas emissions by 86%, compared to fossil fuels.
Literature on sweet sorghum is a prized gift for a VIP visitor.

❖❖ Many improved sweet sorghum female hybrid parents and restorer lines were developed and new hybrid combinations were identified to exploit heterosis for sugar yield. ❖❖ Adopting the right cultivars and crop production technology, including technical backstopping, enhances on-farm yields by 50- 160%. ❖❖ There are no food-fuel tradeoffs with sweet sorghum cultivation as farmers realized 1.5 to 2 t ha-1 sugar yield and 2 to 2.5 t ha-1 grain yield, from demonstrations in their fields. ❖❖ About 50 liters of ethanol can be produced per ton of sweet sorghum stalk. ❖❖ It was shown that a multi-feedstock based distillery with government policy support can be sustainable. ❖❖ Sweet sorghum bagasse (residue after crushing) with leaves is a valuable feed resource. Complete feed blocks based on bagasse are highly palatable, cost effective, and improve yields of both milk (cows) and meat (sheep). ❖❖ Syrup from sweet sorghum juice can also be used as a biofuel feedstock as well as sugar substitute in the pharma and food industries.
❖❖ Varieties SPV 422 and ICSV 93046 are being widely cultivated in the Philippines for vinegar production and allied uses, and will be released in 2012. ❖❖ Technical backstopping on sweet sorghum cultivar choice, cultivation and utilization was provided to many distilleries in India, the Philippines and China. ❖❖ Varieties ICSV 93046, ICSV 25274 and ICSV 25280 have been identified for release in India due to their superior performance at the All India Coordinated Sorghum Improvement Project (AICSIP) multi-location trials in three years. ❖❖ About 4000 samples of improved sweet sorghum female hybrid parents, restorers/ varieties and hybrids have been supplied to over 42 countries.
Crushing the stalks to extract juice.
The impacts
❖❖ Many sweet sorghum hybrids were developed by seed companies using ICRISAT-bred materials. ❖❖ The first sweet sorghum hybrid released in India was CSH 22SS in 2005. The female hybrid parent (ICSB 38) was from ICRISAT.

The innovation
❖❖ Research on genetic enhancement at ICRISAT showed good variability for stalk sugar content and juice volume in sweet sorghum, providing ample scope to improve genotypes for high sugar/ethanol yield. ❖❖ The G X E interactions are significant, hence cultivars need to be customized for different agro-ecological zones and seasons. ❖❖ The heterosis for candidate traits for sugar yield, ie, stalk and juice yield, has been identified. However, no significant heterosis for Brix% was observed.

Seed Systems in sub-Saharan Africa Facilitating access by poor farmers to seeds of ICRISAT’s improved varieties in sub-Saharan Africa Overview
Commercial agriculture is growing in importance, requiring that seed systems deliver high-quality seed of food crops and meet market demands of agro-processors. Numerous constraints limit the performance of seed systems in subSaharan Africa including limited access to seed of new varieties; limited supplies of seed; and the lack of enabling policies and institutional environments. ICRISAT works with partners to support development of open seed markets and local seed companies for supply of quality seed at affordable prices. Sale of seed in small packets makes it easy for poor farmers to buy improved varieties.
v Over 450 farmers organized as farmer clubs, farmer field schools and farmer marketing groups linked to the nongovernmental organization, CARE; 233 farmers linked to NASFAM, and 73 farmers linked to the Millennium Villages Project have produced more than 2,808 tons of certified groundnut seeds during the past 4 years under the Tropical Legumes 2 project partnerships. v In Tanzania, certified seed is produced by over 100 farmer groups under similar contracting arrangement. They produced a total of 376 tons of certified groundnut seed for the Agricultural Seed Agency during the past 4 years. v In West and Central Africa (WCA), ICRISAT supported the development of local seed companies under the West Africa Seed Alliance.
The innovation
Seed Categories Breeder seed is directly controlled by the originating plant breeder, sponsoring institution or firm that supplies the initial source of seed. There are no certification standards for breeder seed. Foundation seed is pure seed produced from breeder’s seed (or foundation seed) under the control of the originator or sponsoring institution or licensee, and maintained by companies or state agencies.
v To guarantee sustained production, ICRISAT has arranged contract farming for seed production through a seed revolving fund (SRF) in eastern and southern Africa (ESA) and community-based seed systems in West and Central Africa (WCA). v Long-term training in seed production has been linked to SRF activities, through the National Smallholder Farmers’ Association of Malawi (NASFAM), the Agricultural Seed Agency in Tanzania, local seed companies under the West Africa Seed Alliance, NGOs such as the Citizen’s Network for Foreign Affairs, and an agro-dealer network for input supply and output marketing.
The impact
v Currently the combined efforts of ICRISAT and national systems provide 27 tons breeder seed of the five popular released groundnut varieties annually. v Seed production has been going on for 12 years. So far, the SRF has contributed 707 tons of foundation seeds and 1,380 tons of certified seeds of improved groundnut varieties, and 12.21 tons breeder and 197.40 tons foundation seed of improved pigeonpea varieties for Malawi. A groundnut seed production plot.
Registered seed is produced from foundation or other approved seed stocks. The seed must be of a quality suitable for the production of certified seed.
v Community-based organizations produced more than 130 tons of certified seed and over 1,000 tons of Quality Declared Seed v In Niger and Mali, 124 farmer associations and 98 smallholder farmers were trained in seed production technologies and business skills. v Adoption rates of improved varieties is estimated at 57% of the total area in Malawi, 35% in Tanzania, 59% in selected districts of Uganda and 57% in Zambia for ESA, 27% in Mali and 22% in Nigeria for WCA. v The reductions in unit costs of improved varieties range from 21% in Malawi to 44% in Uganda, compared to local varieties.
Certified seed is produced from foundation, registered, certified, or other approved seed stocks. It must be verified to be pure with a high germination rate, and cannot be used to produce certified seed again without the approval of the state certification agency. Seed lots must meet specified standards and pass field inspection before being sold as certified seed. Quality declared seed is from a system of seed quality control developed by FAO that is less expensive than regular certification procedures.
