Sorghum and pearl millet are critical sources of income and staple food grain for about 120 million people of West and Central Africa.

Targeting sorghum and pearl millet variety development to poor soil conditions in West Africa

T

hrough an integrated genetic and natural resource management approach, solutions to improve sorghum and pearl millet production in low phosphorus (P) soil conditions of West Africa were developed by ICRISAT and partners under a GIZ/BMZ-supported project. Over the past four years, Sahelian pearl millet and sorghum landraces and breeding materials were characterized for their tolerance to low-P soils, promising materials were identified, and capacities strengthened to evaluate this complex trait by national agricultural research system breeders in Burkina Faso, Mali, Niger and Senegal. These achievements and promising results were presented in a wrap-up workshop of the project “Tackling abiotic production constraints in pearl millet and sorghum-based agricultural systems of the West African Sahel” held on 23-25 March at the ICRISAT Training and Visitors Center in Niamey, Niger.

“Through the project, about 300 accessions were screened and tested. We were able to gather all the genetic material of West Africa and made them available to breeders of each national institute. Top-crosses were made from these materials, some of which were used to form heterotic pools. Now breeders of participating countries have access to genetic materials that can really thrive in poor soils,” said Dr Ousmane Sy, a breeder from the Senegalese Institute for Agricultural Research (ISRA). Under the project, contrasting sets of material were evaluated for possible components of low-P tolerance. Lysimetric screening facilities were developed at the ICRISAT Sahelian Center and used to assess the relative importance of drought, low-P soils and their interactions on millet productivity, to identify adaptation mechanisms that can be exploited for the development of new multi-stresstolerant varieties. to page 2 ...4
