Combining ability analysis in pearl millet [Pennisetum glaucum (L.) R. Br.] for yield and yield contributing traits
Abstract
In the present study, a set of six female (lines) and seven restorers (testers) of pearl millet were crossed in Line × Tester mating fashion. The newly synthesized hybrids were evaluated for yield performance during Summer, 2020. The high magnitude of SCA variance indicates the predominance of non-additive gene action for all the characters. Hence, the heterosis breeding method is suggested to exploit this kind of gene action. The estimates of gca effects for yield and its component characters were high in the line ICMB 04111 and the tester PT 6029. Considering the per se performance, gca of parents, sca effect and standard heterosis over hybrid CO 9 for yield and yield related characters, the hybrid combination ICMB 04111 × PT 6029 was identified as superior followed by ICMB 04111 × PT 6317, ICMB 15666 × PT 7043 and ICMB 99222 × PT 6029. Hence, these hybrids could be further evaluated and exploited commercially.
Keywords: Pearl millet, Line × Tester, combining ability and heterosis.
