Heterotic pools in African and Asian origin populations of pearl millet [Pennisetum glaucum (L.) R. Br.].

ABSTRACT: Forty-five African or Asian origin pearl millet populations bred either in Africa or Asia were investigated to generate information on heterotic pools. They were clustered into seven groups (G1 to G7) when genotyped, using 29 highly polymorphic SSRs. Fourteen parental populations representing these seven marker-based groups were crossed in diallel mating design to generate 91 population hybrids. The hybrids evaluated at three locations in India showed mean panmictic mid-parent heterosis (PMPH) and better-parent heterosis (PBPH) for grain yield ranging from - 21.7 to 62.08% and - 32.51 to 42.99%, respectively. Higher grain yield and heterosis were observed in G2 × G6 (2462 kg ha^-1, 43.2%) and G2 × G5 (2455 kg ha^-1, 42.8%) marker group crosses compared to the most popul
