ItemCombining ability for grain yield and grain components of sorghum hybrid containing high lysine, threonine, iron and zinc content in mali(Ms. Pranali K. Rangari, 2021-07) Maiga, A.M.; Diallo, A.G.; Touré, A.Sorghum is a staple food in Mali, yet grain yields are low and do not contain high lysine, threonine, iron and zinc content. The development of fortified hybrids could generously enhance grain yields and nutrients content for smallholders’ farmers. In the present study, male parents KO- BC1-F6-1053, SB-BC1-F6-1090, SB- B BC1-F6-1036, SB- BC1-F6-1053 and female parent 216-2AP4-5 identified as a good general combiners for the most of the characters under study. The predominance of additive gene action was observed and high heritability were identified in the inheritance of these traits. Twenty hybrids had significant better parent heterosis for grain yield. For the mineral content (iron and zinc), four hybrids obtained a better parent heterosis for ion and then zinc. Seven hybrids obtained a significant better parent heterosis more productive, stable and well adapted for studied zones. Top hybrids for high yield 12A/BE-BC1-F6-2070 (4610.5 kg/ha) and 216-2AP4-5/KO-BC1-F6-1053 4608.2 (kg/ha) identified as superior based on per se performance and specific combining ability in the one of the parents. The identified crosses and parents are worthy to be utilized for the future breeding.
