Phenotypic and genotypic correlations among grain yield and components of yield, viz., clusters per plant, pod number, pod length and grains per pod were studied in 30 grain type varieties of cluster bean (Cyamopsis tetragonoloba (L.) Taub). The varieties showed significant differences for each of the characters studied. Grain yield exhibited positive association with clusters per plant, pod number, pod length and grains per pod. Path coefficient analysis revealed that of all the characters studied clusters per plant, and grains per pod had the maximum direct positive effect on grain yield. The positive association of pod number and pod length with grain yield was due to their indirect effects through clusters per plant and/or grains per pod. In fact the direct effect of pod length on grain yield was negative.
