Combining ability analysis for grain yield and components traits in aromatic rice (Oryza Sativa L.) under transplanting condition

Abstract:
Combining ability analysis was carried out for grain yield and its component traits in line x tester mating design from a systematic set of crosses. The analysis of variance of combining ability revealed significant differences among parents, crosses and interaction (line x tester) for all the traits. General combining ability effects indicated that, IET 12016 was found best general combiner for grain yield per plant, panicles per m2 and number of spikelet’s per panicle. Among the tester, Pusa Sugandha-4 was found best general combiner for most of the traits studied. The crosses IET 19695 / Pusa Sugandha 4, IET12016 / Pusa Sugandha 4 and IET 19695 / Pusa Sugandha 4 were the best specific combiner for grain yield and panicles per m2. The superior crosses were found to involve at least one parent with high gca and other parent having high, average and low gca effects.
