Improving sorghum’s drought and heat tolerance through the use of new genomic tools will benefit the smallholder famers in the drylands.
USAID-supported project to apply genomics research to sorghum improvement
A
n international team led by the University of Georgia’s Plant Genome Mapping Laboratory will work toward sustainable intensification of sorghum production, in a US$4.98 million initiative recently funded by the US Agency for International Development (USAID). New genomics tools will be used to address urgent needs for a more drought resilient food supply, increase rates of sorghum improvement to better meet long-term population growth, and investigate production systems that promote sustainable farming, particularly regarding preservation and/or restoration of soil resources and water quality. “The project offers a unique opportunity to fully exploit the potential of new genomic tools in improving efficiency and effectiveness of sorghum improvement programs,” said ICRISAT Director General William D. Dar. “The smallholder farmers in the drylands will be the final beneficiaries of this
research, contributing to move them from impoverished subsistence farming to prosperous market orientation.” ICRISAT in its stations in Africa and headquarters in India, will actively participate in the project by coordinating and leading the major goal on improving sorghum’s drought and heat tolerance, and will have active involvement in the goal on improving ratooning ability in sorghum. The project also plans to explore transforming sorghum production systems by initiating the development of perennial varieties of sorghum adapted to key agro-ecologies in sub-Saharan Africa. The outcome from this research will help to evaluate possibilities of reaping multiple crops from single plantings, and increasing the extent and duration of soil cover by plant roots to mitigate disadvantages of conventional annual crops including soil erosion and nutrient leaching.
