Genetic diversity for yield and yield attributing traits in chickpea (Cicer arietinum L.)under different moisture regimes

Abstract

The study was carried out during Rabi 2017-18 at College of Agriculture, Vijayapur using 61 chickpea genotypes,involving Multiparent Advanced Generation Intercross (MAGIC) population derived lines and advanced breeding lines toanalyse the genetic diversity under well watered and moisture stress conditions. Based on D2 analysis, the sixty onegenotypes were grouped into ten and two clusters under well-watered (E1) and moisture stress conditions (E2)respectively. Among the ten clusters formed under E1, Cluster I was the largest with 51 genotypes, while the largest clusterunder E2 had 60 genotypes. The highest ranking was recorded for Cluster I under both the environments. The inter clusterdistance varied from 5.20 to 49.68and 89.34 to 544.95 under E1 and E2 respectively. The contribution of 100 seed weightand number of pods per plant was found to be maximum for genetic divergence
