Correlation and Path Analysis Study in Dolichos Bean (Lablab purpureus L.)

Present investigation was carried out at Department of Horticulture, Sam Hingginbottom Institute of Agriculture, Technology and Sciences, Allahabad, U.P. during 2015-2016. The experimental material comprised of thirty genotypes of dolichos bean and the experiment was laid out in Randomized Block Design with three replications. Green pod yield per plant was significantly positive correlated with 100 seed weight, pod length, pod width, number of pods per inflorescence, number of seeds per pod, pod weight, vine length, number of green pod pickings and days to last green pod harvest. 100 seed weight showed highest direct positive effect on green pod yield per plant followed by number of pods per inflorescence, days to last green pod harvest, pod length, days to first flowering, vine length, pod width and number of seeds per pod. While other traits like YBMV incidence %, pod weight, number of green pod picking, days to first pod harvest, number of flowers per inflorescence, inflorescence length showed direct negative effect on green pod yield per plant at genotypic as well as phenotypic level.
