Online published on 8 April, 2015. Abstract Correlation and path analysis were studied in twenty four genotypes of vegetable type cluster bean for growth and yield contributing characters. Estimated yield per hectare exhibited highly significant and positive correlation with plant height, pods per plant, pod length, pod breadth, fresh weight of ten pods, yield per plant and yield per plot at genotypic level and with plant height, pod length, yield per plant and yield per plot at phenotypic level. The results of path analysis also highlighted positive and direct effect of number of leaves, days to first flowering, clusters per plant, pods per cluster, pod length, yield per plant and yield per plot on estimated yield per hectare. Number of branches exhibited positive indirect effect through number of leaves, days to first flowering, clusters per plant, yield per plant and estimated yield per hectare. Fresh weight of ten pods showed positive indirect through number of leaves, days to first flowering, pods per cluster, pod length, yield per plant and yield per plot. The negative direct effects were shown by plant height, number of branches, days to 50% flowering, pods per plant, pod breadth and fresh weight of ten pods.
