Abstract:
Lentil (Lens culinaris Medik) is a major grain legume crop in our country which is grown during rabi season. This experiment was carried out in CAU Research Farm, Andro to study the genetic variability, correlation and path coefficient of twenty lentil genotypes during rabi 2018-2019. These genotypes exhibited significant variability in respect of fifty percent flowering, days to maturity, plant height, pods per plant, number of branches, number of seeds per plant, biological yield per plant, seed yield per plant, harvest index, hundred seed weight and yield/ ha. Genetic variability studies showed presence of good amount of variation among the twenty genotypes. The highest PCV and GCV were recorded for the characters number of pods per plant, number of seeds per plant, biological yield per plant and seed yield per plant. GCV ranged from 4.14 (days to maturity) to 31.37 (number of pods per plant). High heritability coupled with moderate to high genetic gain and GCV observed for number of branches, number of seeds per plant, biological yield, seed yield per plant and 100 seed weight. The seed yield was significant and correlated positively with all the traits except days to fifty percent flowering and days to maturity. Path analysis showed that biological yield per plant, number of branches per plant and harvest index were the three important characters for yield improvement. Based on present investigation, correlation coefficient and path analysis may be utilized for the selection of genotypes for future lentil breeding programme.
