Background: Lentil is the major cultivated pulse crop in the state of West Bengal in terms of total area coverage under cultivation. Selection of high yielding and better quality genotype is the prime vital matter to increase productivity. Investigation and a better understanding of the variability existing in a population base of the crop are pivotal to crop improvement so that the plant breeders can exploit it. Methods: The current study has been carried out at the experimental farm of the University of Calcutta during 2016-2017 in a plot designed with the randomized block design. It was carried out to estimate the magnitude of genetic variability, heritability and genetic advance of fifty-four lentil germplasms. Result: Moderate to high heritability, GCV, PCV, GA and GA % of mean was obtained by days to1st flowering, days to 50% flowering, pods per plant and harvest index. The genotypic and phenotypic association of seed yield was significantly positive with traits like plant height, pods/plant, 100 seed weight and harvest index. Characters like days to 50% flowering, plant height, primary branches per plant, pods/plant, pod length, 100 seed weight and harvest index shows a positive direct effect on seed yield in path analysis suggesting select for such traits while exercising selection for seed yield per plant in lentil.

“…All the short duration genotypes were grouped into cluster II whereas cluster I included long duration genotypes indicating maximum contribution of this character towards the divergence between cluster II and I. Gautam et al (2014) also reported early maturing genotypes in cluster II and late maturing genotypes in cluster III. The genotypes which are grouped into the same cluster probably disperse very little from one to another (Roy et al, 2013).…”

“…This genotypes contained maximum value mean value for different traits such as number of pods peduncle -1 , number of pods plant -1 , number of seeds plant -1 , 100-seed weight, and seed yield plant -1 (Table 4) which indicates that this genotypes could get the maj or priority for the yield improvement. Earlier Gautam et al (2014) observed moderate to high yield donating traits in cluster III and II in the lentil genoypes. The members of cluster I were BD-3810, BD-3945, BD-3948, BD-3985 and BD-4134, the members of cluster II were BD-3804, BD-3808, BD-3975, BD-3995, BD-5958 and BD-5959.…”

Lentil is an important pulse crop with high nutritional value and high market price worldwide. Molecular markers have emerged as useful tools to assess the genetic diversity across crops. The study was conducted to explore genetic diversity of twenty lentil genotypes considering yield and yield attributing traits. Among all genotypes, BARI Masur-6, BARI Masur-7 followed by genotypes BD-3806 and BD-4090 showed the highest value of yield attributing traits therefore, these genotypes are considered as best performer. The results of cluster analysis based on the Ward’s method grouped the genotypes into three clusters and the genotypes of cluster III revealed the maximum value for yield per plants which indicated their importance in the selection for yield improvement program of lentil. Afterwards, 20 genotypes were evaluated through 7 sets of SSR primers to assess genetic diversity among the genotypes. Among them, four sets of primers viz., SSR 19, SSR 33, SSR 90 and SSR 213 showed high polymorphism which suggesting the greater genetic diversity in the genotypes. The unweighted pair group method of arithmetic mean (UPGMA) dendrogram based on Nei’s (1973) genetic distance led the genotypes into four major clusters which showed a bit deviation with the morphological cluster. The findings of this study will be very useful for selection of appropriate parents and the genetic understanding for the set up for future systematic lentil breeding programs.

“…In genetic improvement of a crop the type and extent of variability is desired in considerable characters. Information on the nature and magnitude of genetic divergence in population helps for choosing of diverse parents in meaningful hybridization [1]. The study of genetic diversity among genotypes is helpful in designing effective crop breeding strategy in lentil [2,1,3,4,5,6].…”

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.
