Study of Correlation and Path Analysis for Green Pod Yield and Its Contributing Traits in Vegetable Pea (Pisum sativum L.)

Abstract

Correlation at genotypic and phenotypic levels along with path coefficient analysis were studied for various yield and its component characters in twenty genotypes of pea (Pisum sativum L.) during rabi, 2009-10. Analysis of variance revealed significant difference for all the characters indicating the presence of good amount of variability in the genotypes studied. Correlation studies revealed that green pod yield per plant was positively and significantly associated with pod length, pod weight and number of grains per pod. Path coefficient analysis revealed that traits like number of pods per plant, pod weight, number of grains per pod, number of pickings and protein content were the important characters for selection of high yielding genotypes as they exerted high positive direct effect as well as positive correlation with green pod yield per plant. The result suggested that these traits could be considered as major yield contributing traits in pea.
