Correlation and path analysis studies were conducted to determine the association among various seed yield and its component traits, and the direct and indirect contribution towards seed yield in 80 elite diverse fababean genotypes collected from different geographical areas among them 31 are exotic types and 49 are indigenous types. Seed yield per plant had a positive and highly significant genotypic and phenotypic correlations with days to 50% flowering(41.67 and 96.33), days to maturity(142 and 195.33), plant height, number of branches per plant, number of pods per plant, number of seeds per pod and 100 seed weight. Path coefficient analysis indicated that 100 seed weight had the highest direct and positive effect on seed yield per plant followed by number of pods per plant, number of seeds per pod, days to 50% flowering, number of branches per plant, plant height. So, from the combined results of correlation coefficient and path analysis, it may be concluded that 100 seed weight, branches per plant and number of pods per plant are the major yield contributing traits to be given selection pressure for improving yield.
