Abstract:

 Pea Pisum sativum L. a member of the Fabaceae family is one of the most significant pulse crops due to its high nutritive values compared to other pulses. The yield potential of local varieties is very low as compared to varieties of other countries. The present study was sown under a randomized complete block design RCBD to explore the genetic variability of various quantitative parameters in 30 genotypes of peas with three replications. Data were collected for traits like days to first bloom, 50 flowering time, maturity, plant height cm, distance between the nodes cm, total number of nodes per plant, total number of pods per plant, pod size cm, width of pods cm, total number of seeds per pod, 100 seed weight g and yield per plant g. The results revealed that all the genotypes revealed substantial differences for the traits under study. The estimates of broad sense heritability revealed that high heritability was observed among all the attributes and the number of pods per plant exhibited maximum heritability. The dendrogram constructed from the genotypic data grouped 30 genotypes into three major groups. Cluster one was the largest sub-divided into two sub-clusters containing 13 genotypes followed by cluster two includes 6 genotypes that are comparable to each other. The greatest inter-cluster distance was found among clusters 2 and 3 87.87. Correlation analysis revealed that the height of the plant, nodes per plant, the width of the pod, number of pods per plant, pod size, number of seeds per pod, and 100-seed weight showed positive and extremely significant association by the yield per plant. Path coefficient analysis showed that 50 flowering time followed by pods per plant exhibited a maximum positive effect on plant yield.
