Abstract:
The experiment was carried out during late Rabi season, 2019-20 with twenty seven blackgram genotypes at Bagusala Farm, M. S. Swaminathan School of Agriculture, Centurion University of Technology and Management, Paralakhemundi, Odisha to study the inter-relationship and cause effect for yield and its attributes of Blackgram in randomized complete block design with three replications. The results highlighted that the yield per plant had significant to highly significant positive correlation at phenotypic level with plant height, number of clusters per plant, number of pods per cluster, number of pods per plant, pod length, pod weight, and seeds per pod. The magnitude of genotypic correlations was found to be higher than phenotypic correlations for all the quantitative characters under studied indicating the prominence of additive x additive gene action and less effect of environment. Path coefficient analysis showed highest positive direct effect on the dependent character like yield per plot by 100-seed weight followed by number of clusters per plant, days to 50% flowering, protein content, number of secondary branches, pod weight per plant at phenotypic level. Henceforth, these traits would be given an importance during selection procedures to improve yield and scope for simultaneous improvement of these traits.
