Forty five cluster bean genotypes (Cyamopsis tetragonoloba (L.) Taub) were evaluated to find out the correlation and path analysis for vegetable pod yield and yield attributes during kharif 2018 at College of Horticulture, Anantharajupeta, Andhra Pradesh. Character association of the yield attributing traits revealed that fresh pod yield per plant had highly significant and positive association with pod length, number of pods per plant, number of pods per cluster, number of pod clusters per plant and number of branches per plant at maturity. Direct selection based on these traits could result in simultaneous improvement of afore said traits and marketable pod yield in cluster bean. From path analysis, it can be inferred that very high positive direct effect on fresh pod yield per plant was exerted by number of clusters per pod at genotypic levels while pod length, number of pod clusters per plant, number of pods per plant and number of clusters per plant exerted a positive and high direct effect on fresh pod yield per plant at both genotypic and phenotypic levels. High negative direct effect on fresh pod yield per plant was exerted by days to first flowering and days to 50 % flowering. High direct effect of these traits appeared to be the main factor for their strong association with pod yield per plant. Hence direct selection for these traits would be highly effective in improving the pod yield per plant.
