 Abstract. The study was carried out during 2014–15 on twelve elite pea genotypes. On the basis of obtained results, the following conclusion was drawn and can be used for further breeding program. The analysis of variance revealed the existence of significant differences among the genotypes for all the traits except seed yield per plant. The phenotypic coefficients of variation (PCV) were slightly higher than their corresponding genetic coefficients variation (GCV) due to the influence of environment on character expression. High heritability estimates for all characters except pod weight per plant and seed yield per plant. High heritability for these traits indicated that selection could be more effective for genetic improvement. The path coefficient analysis showed that 100–seed weight, chlorophyll content, pod length and number of seed per pod had maximum direct effect on grain yield per plant.
