Abstract

An experiment was conducted to assess the genetic variability for quantitative and qualitative traits in 52 desi chickpea genotypes. The significant variation was observed for all the traits. High phenotypic and genotypic coefficient of variation was observed for single plant yield followed by hundred seed weight, number of secondary branches, number of pods per plant, number of seeds per plant and first pod height. High heritability along with a high estimate of genetic advance expressed as per cent of mean was exhibited for single plant yield, hundred seed weight, number of secondary branches, number of pods per plant, number of seeds per plant and first pod height. Cluster analysis based on eight qualitative characters grouped all 52 genotypes into eight major clusters at 0.48 similarity coefficient value. Cluster I was found to be the largest one with 16 genotypes while, cluster VI and VIII were the smallest one with single genotype each (CB PLS 5433 and CB RC 110-2). A marked difference was observed between the genotypes for the qualitative traits indicating the importance of such traits in germplasm characterization.
