The research involved the analysis of 29 recombinant inbred lines (RILs) in randomized block design (RBD) with three replications along with two checks viz., Markanday and Vipasha. The lines were evaluated at Research Sub Station, Berthin, District Bilaspur (HP) and Department of Seed Science and Technology, CSK HPKV, Palampur, District Kangra (HP) during rabi 2019-20. Using DUS characterization, the variability in the expression of 13 distinguishing traits was observed at seed and plant levels. Seed size, seed colour, foliage colour, anthocyanin colouration on stem, leaflet size, plant growth habit and plant height were found to be the most useful characters for sound classification of lentil genotypes. Sufficient variability was observed for almost all yield related attributes and seed quality parameters. PCV values higher than GCV indicated that the apparent variation was due to the influence of both genotype and environment. High genetic advance as percentage of mean along with high heritability was observed for pods per plant, seeds per pod, biological yield per plant (g), seed yield per plant (g) and harvest index (%) suggesting their potential towards response to selection. Most of the RILs showed good response towards Fusarium wilt, indicating the transfer of disease resistant genes from the parents. Cluster analysis grouped the genotypes into six clusters with CI RIL 9 and C2 RIL 79 being the most diverse. C1 RIL 43, C1 RIL 58, C1 RIL 53, C1 RIL 62, C1 RIL 65 and C2 RIL 75 surpassed the best check ‘Vipasha’ for most of the traits under study. Out of these RILs, C1 RIL 65 proved to be a promising genotype for yield related attributes and C1 RIL 58 performed well for all seed quality parameters.EnglishThesis
