“…Trait wise coherent selection of genotypes from above clusters, yields desirable improvement in novel super-early pigeonpea. These findings are in agreement with Sreelakshmi and Shivani (2015), Patel et al, (2018), Rajamani et al, (2014) and Kumara et al, (2013).…”

The present investigation aimed to study genetic divergence and clustering pattern of 37super-early pigeon pea genotypes. Analysis of variance and hierarchical cluster analysis of tocher's method revealed significant differences among the genotypes for all the traits under study. Based on genetic distance (D 2 value), the 37 genotypes were grouped into 9 distinctive clusters, of which cluster I and II formed the largest clusters with 10 genotypes in each. Among all the characters understudy, leaf area index(LAI) at 60 DAS contributed more to the divergence followed by leaf area (17.02) and leaf area index (12.71) at maturity. Based on the average inter-cluster distance, the cluster III and IX (66.93) tailed by cluster III and VIII (64.86) and cluster VI and VIII (64.06) showed higher inter-cluster distance depicting the wider divergence. Trait-wise selection of diverse parents from the above clusters aids in exploitation of heterosis in superearly pigeon pea.

Background: Pigeonpea is an important legume crop in India. The super early genotypes which matures within 100 days have been developed at ICRISAT. They are photo-insensitive, aids in crop intensification and escapes abiotic and biotic stresses. The super early genotypes were exploited for genetic diversity for further improvement of the genotypes. Methods: The study was conducted at International Crop Research Institute for the Semi-Arid Tropics, Patancheru, Telangana during kharif, 2017. The thirty-super early pigeonpea genotypes developed at ICRISAT were subjected for the study of genetic diversity (Mahalanobis D2 method) based on twelve quantitative characters. Result: The 30 super early genotypes were grouped into five clusters. The largest number of genotypes were confined to cluster III (19 genotypes) followed by cluster IV (6 genotypes), cluster I and II (2 genotypes). Cluster V is a solitary cluster with the check MN1.The inter cluster distance was high between the clusters III and IV followed by cluster I and III. The intra cluster distance was highest for the cluster III indicating the presence of variation among the genotypes within the cluster. The highest mean for single plant yield was observed for the cluster III followed by cluster V. The clusters with more inter cluster distance can be used to select parents to be involved in hybridization programmes.
