ABSTRACT

An experiment was conducted in the year 2009 to estimate genotypic and phenotypic correlations in all possible combinations for seventy five accessions of black gram with the object to get the information on relative importance of various yield contributing characters and thus increase the efficiency of selection for higher yield based on yield components. The characters, plant height, number of primary branches per plant, number of pods per plant, number of seeds per plant, number of seeds per pod and 1000-seed weight showed positive correlation with seed yield both at phenotypic and genotypic level. The magnitude of genotypic correlation was higher than phenotypic correlation indicating that the association of traits with seed yield controlled by genetic factors like linkage and/ or pleiotropism. Path coefficient analysis indicated that characters namely number of seeds per plant and 1000-seed weight had high magnitude and positive direct effect on seed yield.
