Genetic variability in lentil (Lens culinaris M.) genotypes for seed and seedling characteristics

Abstract

In this study, thirty genotypes of lentil (Lens culinaris M.) were evaluated in randomized block design with three replications during 2017-18 in laboratory of Department of Plant Breeding and Genetics, SKN college of agriculture, Jobner to determine genetic variability, heritability and genetic advance for seed and seedling characteristics. Observations were recorded on 100 seed weight, seed volume, true density, bulk density, porosity, water absorption capacity, water absorption index germination, seedling length, seedling fresh weight, seedling dry weight and seedling vigour index. The analysis of variance indicated significant difference among genotypes and considerable variability with respect to all the characters except germination percentage. The highest PCV and GCV expressed as percentage was observed for porosity followed by seed volume, seedling length and seedling vigour index, whereas low for bulk density and water absorption index. The estimates of heritability were high for all the characters ranging from 61.39 to 97.37. The estimate of very high heritability with high genetic advance was observed for seed weight, seed volume, water absorption capacity and seedling dry weight whereas high heritability with low genetic advance was recorded for bulk density.
