Abstract:
A field experiment was conducted during rabi 2018 for study of genetic diversity in 60 different genotypes of chickpea using D² statistics method of Mahalanobis (1936) ^[6]. The 60 genotypes of chickpea were grouped intofive clusterssuggested the presence of wide genetic diversity among them. The clustering pattern of the genotypes was independent of their geographical distribution. Among different twelve traits studied, protein content, 100-seed weight, number of secondary branches per plant, seed yield per plant, height at first pod, seed volume per weight, days to 50% flowering and number of primary branches per plant contributed very much towards genetic divergence. Based on inter-cluster distance, clusters III and IV followed by IV and V, and II and IV had maximum inter-cluster distance. Therefore, it is concluded that the genotypes belonging to these clusters should be inter-crossed in order to generate more variability and improving seed yield in chickpea.
