Abstract

The experiment was conducted using 140 lentil genotypes at (farm name?) Bihar Agricultural University, Sabour, Bhagalpur in 2017-18. The genetic divergences were estimated using D2 analysis where a number of clusters were formed considering all genotypes of indigenous and exogenous types. Genetic variation of genotypes in considerable traits was significant for selection of desired type that can be utilised in future breeding programme. The study on correlation, genotypic variability, and path analysis of seed yield and yield components were essential for determining the relevance of considerable traits in enhancement of seed yield. The total genotypes were grouped into 5 clusters viz. Cluster I was found to be the largest comprising 121 genotypes, followed by cluster III of 12 genotypes. Cluster II, IV had three genotypes each and V was monogenic. Seeds per plant, days to maturity and pods per plant contributed extreme divergence among the genotypes which can be integrated in enhancement of productivity of lentil. On the basis of cluster mean, intra and inter cluster distance and per se cluster III, IV and V may be used for their desired characters in breeding strategy. The genotypes BRL-1, BRL-2, BRL-3 LKH-1, LKH-2, LKH-3, FLIP 2010-73L-2, FLIP 2010-86L and X2011S-111-2 may be considered in breeding to gain high heterotic effect and also to improve the desirable transgressive segregants.
