One hundred twenty field pea (Pisum sativum L. var. arvense) genotypes were evaluated with four check varieties viz., Ambika, Rachna, HFP 8909 and HUDP 15 to assess the genetic variability, association of different yield traits and direct & indirect effects of these traits on seed yield. Analysis of variance (ANOVA) revealed significant differences among all the genotypes for majority of the traits except number of primary branches per plant. The genotypes showed moderate to high level of genotypic coefficient of variance (GCV) and phenotypic coefficient of variance (PCV). The magnitudes of phenotypic coefficient of variance (PCV) for all the characters were slightly higher than their corresponding genotypic coefficient of variance (GCV), indicated very less environmental influence on the expression of the characters. Higher estimate of GCV (30.414) was recorded for number of seeds per pod followed by seed yield per plant (28.874). Correlation analysis indicated that seed yield per plant exhibited highly significant and positive correlation with harvest index, seeds per pod, pod length and 100-seed weight. Path analysis indicated that the highest positive and direct effect on seed yield per plant was exerted by harvest index and seeds per pod. Highly positive indirect effect on seed yield per plant was exerted by harvest index via seeds per pod, pod length and biological yield per plant. The characters identified above as important direct and indirect yield components can be used in formulation of selection strategy in field pea for selection of high yielding genotypes.
