Clustering of cotton (Gossypium hirsutum L.) inbreds for seed cotton yield and its attributes based on genetic divergence

Twenty-eight newly developed cotton inbreds were evaluated for clustering based on genetic divergence. The set of inbreds were grouped into 4 clusters. Therefore, it is suggested to make the breeding crosses between inbreds from different clusters to get the raise in yield plateau for heterosis breeding and inbred development. Monopodia per plant contributed most in genetic divergence followed by plant height and boll weight. However, It was observed that seed cotton yield and days to 50% flowering showed least percent contribution towards genetic divergence. Further, one, two or more inbred(s) from different clusters may be chosen for further genetic studies either by diallel or Line X Tester analysis.
