Genetic variability studies in lentil (Lens culinaris Medic.) genotypes for seed yield and attributes

Abstract

An experiment was conducted with thirty five genotypes in rabi season of 2016-17.A wide range of variation exhibited for yield and yield attributing traits among the progenies under study. In general PCV was higher in magnitude than GCV. The analysis of variance revealed significant variation among the genotypes for all the characters studied. The estimates of mean sum of squares showed comparatively wide range of variation for the characters number of pods per plant, harvest index (%) and days to maturity while, the lowest variation was recorded for number of primary branches per plant. Highest PCV (50.66 %) and GCV (44.76 %) was recorded by seed yield per plant. Appreciable heritability values were observed for different characters under study. Highest heritability estimates were recorded for the number of seeds per pod (98.81), hundred seed weight(95.57), Harvest index (84.43) and number of pods per plant (84.38). The lowest heritability estimate recorded in number of primary branches per plant and plant height.
