Harnessing Sorghum Landraces to Breed High-Yielding, Grain Mold-Tolerant Cultivars With High Protein for Drought-Prone Environments

Intermittent drought and an incidence of grain mold disease are the two major constraints affecting sorghum production productivity. The study aimed at developing drought-tolerant varieties possessing a high protein content tolerance to with stable performance using additive main effects multiplicative interaction (AMMI) genotype × environment (GGE) biplot methods. Systematic hybridization among 11 superior landraces resulted in subsequent pedigree-based breeding selection from 2010 2015 evolved 19 promising grains such as white, yellow, brown pericarp grains. These were evaluated for their adaptability stability yield 13 rainfed environments three hot spot environments. A variety yellow PYPS 2 (3,698 kg/ha; 14.52% protein; 10.70 mg/100 g Fe) was identified by both AMMI GGE analyses. Four mega-environments fodder yield. Sorghum 2, 4, 8, highly E2 low incidence. Besides meeting nutritional demand smallholder farmers under dryland conditions, these suitable enhancing productivity present climate change scenario.
