Studies on character association and path analysis in garden pea (Pisum sativum L. sub sp. hortense Asch.) Abstract Forty four genotypes of garden pea including checks were evaluated to estimate correlation and path coefficient for seventeen yield contributing traits and identification of superior recombinants for their utilization in crop improvement programme during Rabi, 2016-17, at Main Experimental Station, Department of Vegetable Science, Acharya Narendra Deva University of Agriculture

The most important trait pod yield per plant had exhibited highly significant positive phenotypic correlation with number of pods per plant (0.794) followed by number of nodes per plant (0.253), primary branches per plant (0.231), pod circumference (0.190), shelling percentage (0.184), and number of seeds per pod (0.166). Higher magnitude of positive direct effect on pod yield per plant was exerted by plant height (1.2567) followed by number of pod per plant (0.6431), days to 50% flowering (0.2599), number of seeds per 100g pod (0.1655), node to first flower appears (0.1249), T.S.S. (0.1055), primary branches per plant (0.0940) pod length (0.0439) and 100-seed weight (0.0360). Direct contribution of these traits indicates the scope of improvements through selection for number of pods per plant and number of seeds per pod in the available germplasms.
