Abstract
The present study was conducted during the rabi season of 2021-22 at Crop Cafeteria farm of Shoolini University, Solan (H.P.). The experiment consisted of 245 genotypes of pea with three check varieties viz., PB-89, PP and Arkel. The present investigation was carried out in order to find yield and its contributing traits in pea germplasm. As per correlation analysis and path analysis, the results indicated that seed yield/plant (g) exhibited positive and high significant correlations with 100-seed weight (g), biological yield/plant (g), harvest index (%) and number of pods/plant. Path analysis identified biological yield per plant (g) and harvest index (%) as important direct components for seed yield per plant. High yielding genotypes are- SHP 21, SHP73, JCR/JV-29, JCR/JV-39, IC 107452, 6363/P-3342, IC-629738, P-2236, P-2380, SHP 19, SHP17, SHP 51.
