The present investigation was undertaken to assess the combining ability for dwarfness among the given testers and also to estimate the extent of heterosis for ten different characters in 90 hybrids which were derived by crossing ten diverse cms lines with nine dwarf testers in a line × tester mating design during rabi 2008-09. The resultant hybrids and parents along with standard check RSFH-130 were evaluated for plant height and other yield contributing traits. CMS-107A among lines and R-411R among testers were found to be best general combiners for dwarfness and other yield contributing traits. The best cross combinations for seed yield per plant CMS-104A × RHA-288 and oil content CMS-131A × R-186-1 with high sca effect have been identified. The cross CMS-105A × R-186-1 recorded a significant heterosis over better parent (-10.65%) for plant height and seed yield and the cross CMS-X × R-4-2-Br recorded a significant heterosis over standard check (-37.30%) for plant height.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
