Thirty five divergent genotypes of greengram [Vigna radiata.(L.) Wilczek] were evaluated for yield and yield attributes during rabi, 2009–10. Genotypes differed significantly for all the characters studied. High genetic advance coupled with high heritability was observed for characters viz., plant height, number of pods/plant, shoot dry matter/plant and seed yield/plant, indicating there by the preponderance of additive gene action for these characters. Correlation analysis indicated that seed yield/plant was positive and significantly associated with days to maturity, plant height, number of pods/plant, number of seeds/pod, 100-seed weight, shoot nitrogen, seed protein and shoot dry matter/plant. Path co-efficient analysis revealed that days to flowering, days to maturity, number of pods/plant, seed protein, shoot dry matter/plant and 100-seed weight had positive direct effects on seed yield/plant. Hence, selection on these traits could be improving seed yield in greengram.
