- The project is implemented locally by Africa Harvest Foundation in collaboration with DuPont Pioneer LTD, Kenya Agricultural and Livestock Research Organization (KALRO) and University of Nairobi.
- The Africa Biofortified Sorghum (ABS) project’s strategy aims at improving high yielding, farmer preferred varieties by increasing and stabilizing Vitamin A. The strategy also aims at improving iron, zinc bio-availability and protein digestability.
Research and outreach duties:
- Gene flow studies from ABS germplasm to with local germplasm.
- Breeding local germplasm for improved ABS genes. Introgressing ABS sorghum transgenes (carotenoid biosynthesis pathway genes) for high accumulation of beta-carotene in the endosperm and reduction of phytic acid for improved bioavailability of iron and zinc to allleviate nutrient deficiencies.
- Confined field trials (CFT) and regulatory issues.
- Biosafety of ABS germplasm and segregating populations from hybridization with local gerplasm.
2016 - Launching Meeting of the Network of Environmental Biosafety, July 3-6, Ouagadougou.
