Twelve parents were used in the crossing programme to produce 27 hybrids in L×T fashion during kharif 2015-16. In the field conditions, parents and hybrids were planted in Randomized Block Design of three replications and evaluated for the performance in terms of yield and yield contributing characters during kharif 2016-17. Observations were recorded on ten characters viz., plant height, days to 50% flowering, days to maturity, number of primary branches per plant, number of secondary branches per plant, number of pods per plant, number of seeds per pod, 100 seed weight, grain yield per plant and harvest index. It was observed that increase in number of pods per plant directly contributed to increased yield. Among the twenty seven

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.
