Abstract

The experiment was conducted to assess the genetic variability parameters for eleven quantitative traits in 22 farmers’ Pea varieties during rabi 2019-2020 in randomized block design (RBD) with 3 replications. The ANOVA for all the characters showed 1% level of significance. On an average phenotypic and genotypic coefficient of variation were high for plant height, number of pods per plant, number of effective nodes, number of seeds per plant, harvest index, 100-seed weight and yield per plant. This indicated the presence of sufficient variability among the characters. High heritability coupled with high genetic advance as percent of mean, was observed in characters viz., yield/plant, 100-seed weight, number of pods/plant, harvest index, plant height, number of effective nodes, number of seeds/pod and width of pods, which indicated the preponderance of additive gene action. The yield per plant had significant and positive direct association with days to maturity, width of pods and ha
