Abstract: Field pea (Pisum sativum L.) is one of the most important legume crops in India. In order to develop high yielding variety of field pea explosion of available genetic wealth of these crops is very essential. Therefore, this study was conceived to examine the variability and determine the relative importance of primary and secondary traits as selection criteria to improve productivity. The experiment material comprised of 14 genotypes for thirteen traits with three replications during the year 2016-17 at Bundelkhand University, Jhansi, U.P. Five competitive plants from each plot were randomly selected for recording observation for all the quantitative traits. The analysis of variance was found highly significant for all characters. High heritability and high genetic advance percent of mean plant height followed by harvest index, days to 50 % flowering and biological yield per plant. The genotype showed moderate high level of genotypic coefficient of variance (GCV) and phenotypic coefficient of variance (PCV). The magnitude of phenotypic coefficient of variance(PCV) for all the characters were slightly higher than their corresponding genotypic coefficient of variance(GCV) which indicates very less environmental influence on the expression of the traits. Higher estimate of GCV was recorded for plant height followed by number of secondary branch per plant. Correlation analysis indicates that seed yield per plant exhibited highly significant and positive correlation with harvest index, 100 seed weight and Number of secondary branches per plant. Path analysis indicates that the highest positive and direct effect on seed yield per plant was exerted by biological yield per plant and harvest index. Highly positive indirect effect on seed yield per plant was exerted by number of pods per plant via days to maturity, biological yield per plant and harvest index. The characters identified above as important direct and indirect yield component can be used in formulation of selection strategies in field pea for selection of high yielding genotypes.
