Abstract:

The present investigation was carried out among the 42 germplasm of chickpea, to study the nature and magnitude of genetic divergence using Mahalanobis’s D2 Statistics, during rabi season of 2017 at Naini Agricultural Institute, S.H.U.A.T.S., Allahabad, U.P. Based on D² analysis, the 42 germplasm lines were grouped into seven different clusters indicating diverse nature of material studied. Cluster V was the largest with 12 genotypes followed by cluster VII (10 genotypes) and cluster VI (7 genotypes). Among the seed yield components, seed index followed by number of days to maturity and Biological yield per plant contributed maximum towards the divergence. Cluster I showed the maximum mean value for seed yield. The intra and inter cluster divergence among the genotypes was varying in magnitude. The intra- cluster distance was maximum in cluster III followed by clusters V and VII. The widest inter cluster distance was noted between cluster III and VII followed by IV and VII, II and VII. Genotypes C-108 and C-138 were identified most desirable with high seed yield/plant. Cluster III and VII were most diverse to each other, therefore genotypes present in these clusters are expected to provide a broad spectrum of variability in segregating generations and may be used as parents for future hybridization programme.
