tailieunhanh - Genetic diversity studies in yield and its contributing traits in Groundnut (Arachis hypogaea L.) genotypes using D2 statistics

An experimental trial consisting of 40 groundnut genotypes, study was conducted during kharif, 2017 at Agricultural College Farm, Bapatla, to study the genetic divergence in different characters with yield and yield related traits. The genetic diversity among 40 genotypes for 15 characters was estimated by employing D² statistic. The 40 groundnut genotypes were grouped under seven clusters. Among seven clusters, cluster I was the largest which comprising of 26 genotypes fallowed by clusters II with nine genotypes. The rest of clusters like III, IV, V, VI and VII had shown solitary in nature. The average D2 values of inter cluster distances, showed maximum distance between Cluster-IV and VI () followed by inter cluster distance () between IV and VII. It indicates that crossing between these clusters helps in production of transgressive segregates or better recombinants. Each character had their own contribution to total divergence where, the Oil content and protein content had maximum contribution of and respectively to the divergence of genotypes. | Genetic diversity studies in yield and its contributing traits in Groundnut (Arachis hypogaea L.) genotypes using D2 statistics
