Forty two divergent genotypes of French bean (Phaseolus vulgaris L.) were evaluated for yield and yield attributes during spring season of 2009-10. Genotypes differed significantly for all the characters. High genetic advance coupled with high heritability was observed for 100- seed weight, seed yield/plant, pod yield/plant and pod yield qt/ha, indicating there by the preponderance of additive gene action for these characters. Correlation analysis indicated that pod yield/plant was significant and positively associated with days taken to Ist flowering and Ist picking, pod length and seed yield/plant. Path co-efficient analysis revealed that days taken to Ist flowering, days to Ist picking, pod length, 100- seed weight and seed yield/ plant had positive direct effect on pod yield/ha. Hence, selection on these traits could be improving seed yield in French bean.
