SUMMARY
Correlation coefficient and path coefficient analysis was studied in the present study for seed yield with a set of 40 genotypes of clusterbean (Cyamopsis tetragonaloba (L.) Taub) at Instructional Farm, Department of Agronomy, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar using RBD with four replications. Based on the mean performance, five genotypes viz., GG 1, GG 2, IC 41057, IC 311444, and IC 113432 were found elite genotypes. The correlation coefficient at genotypic level was found to be higher than corresponding phenotypic level, indicating that there is a strong association between yield and yield related traits. Seed yield per plant showed highly significant and positive association with test weight followed by number of pods per plant,
number of clusters per plant, number of seeds per pod, pod length, number of branches per plant, gum content and protein content both at genotypic and phenotypic level. The association of days to flowering and maturity with seed yield per plant was positive, but non-significant whereas, plant height displayed negative and non-significant association with seed yield per plant at genotypic and phenotypic level. Path coefficient analysis revealed the positive direct effect on seed yield per plant by test weight, number of pods per plant and number of seeds per pod.
