Pigeonpea germplasm

The present study was conducted to evaluate the genetic divergence among twenty five pigeonpea germplasm using Mahalonobis D2 statistics for seven different traits during kharif 2015. Analysis of variance depicted the significant differences among the traits which indicated the presence of variability in the germplasm. D2 clustering grouped the genotypes into ten clusters. Based on the intercluster distance (1844.86) cluster VIII and X were the most diversified clusters and genotypes from these clusters can be used in the hybridization programme for further improvement.

Cluster and association analysis were studied for yield maximization and yield attributing traits in pigeonpea [Cajanus cajan (L.) Millsp]. There was significant variation observed for all the characters under study. Association studies revealed that seed yield per plant was positively associated with number of pods per plant, number of pod clusters per plant, number of primary branches per plant and pod length. Cluster analysis result showed existence of considerable diversity in pigeonpea germplasm accessions. The maximum inter cluster distance was observed in between cluster I and VI.
