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
