Association study for seed yield and quality and their contributing traits in cluster bean [Cymopsis tetragonoloba (L.) Taub.] genotypes

Abstract

A correlation study was conducted using cluster bean genotypes collected from ACRIPIDA, RARS, Vijayapura. This study helps in identifying the characters which mainly contributing to the seed yield. Fifteen genotypes of cluster bean were evaluated during Kharif 2017 and observations recorded on growth and seed yield parameters. Correlation studies indicated that seed yield per plant had shown significant and highly positive correlation with parameters viz., dry pod yield per plant (0.51), seed yield per hectare (0.47) and gum content (0.38) and shown positive correlation with number of seeds per pod and protein content. It is negative significantly and correlated with pod length (0.53), number of pods per plant (0.65), seed yield per plot (0.50) suggesting that which parameters may be considered as prime traits during the course of selection to have the higher potential of yield.
