Abstract:A ten parent diallel cross analysis involving bollworm tolerant donor lines of upland cotton was studied for component of variance analysis for seven traits. Both additive and non-additive gene action were important for all the traits except seed index. However the role of dominance was major for all the traits studied. Dominance was ambidirectional for all the traits studied. Epistasis influenced the performance of number of bolls and seed cotton yield. Narrow sense heritability was high for days to 50 per ce… Show more
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.
