Abstract: The present investigation was carried out with a view to study the magnitude of variability, correlation and path analysis excluding reciprocals involving 27 genotypes in blackgram during Kharif - 2018. The experimental material was planted in randomized block design with three replications at the Field Experimentation Centre, Department of Genetics and Plant Breeding, SHUATS, Prayagraj, U.P. The analysis of variance for all the characters revealed that parents were significant for all the characters, indicating presence of considerable amount of genetic variability in the germplasm tested. Harvest index, Number of primary branches, Number of pods per plant, Number of seeds per pod exhibited high GCV, PCV and genetic parameters revealed that heritability (broad sense) and genetic advance as % of mean values were high for Number of primary branches, Number of seeds per pod, biological yield, harvest index, seed yield per plant indicating that selection would be fruitful for improvement of these traitsAmong 27 genotypes studied MU-06 X KPU-13-192 showed high mean performance for seed yield per plant followed by MU-06 X NDUK-13-6, PU-31 and NDUK-13-6 Correlation coefficient analysis revealed that seed yield per plant exhibited positive and significant correlation associated with Plant height, Number of pods per plant, Biological yield and harvest index at both genotypic and phenotypic levels. Path coefficient analysis revealed that characters plant height, number of primary branches, days to maturity, biological yield, and harvest index have positive direct effect on seed yield per plant at genotypic and phenotypic levels.
