Correlation and path analysis in clusterbean (Cyamopsis tetragonoloba (L.)Taub)

Abstract

Correlation studies with fifty one genotypes in cluster bean conducted during summer season revealed that pod yield per plant exhibited highly significant and positive association with pod yield per hectare, pod length, pod weight, number of pods per plant, number of clusters per plant, pod girth, number of branches per plant, plant height, gum content, number of pods per cluster, number of seeds per pod, protein content and fibre content. These characters are to be given due consideration in selection for yield improvement of the crop. Path analysis of fifty one genotypes revealed that maximum positive direct effect on pod yield per plant was exhibited through pod weight followed by number of pods per plant.
