Variation and character association studies in clusterbean (Cyamopsis tetragonoloba (L.) taub.)

Analysis of variance for ten quantitative characters in 81 genotypes of c1usterbean showed significant variability for all the traits. Branches plant⁻¹, pods plant⁻¹, pods c1uster⁻¹ and seed yield plant⁻¹ had high genotypic coefficient of variability, high heritability and high genetic advance (% of mean). Seed yield per plant showed significant and positive correlation with pods per plant, clusters per plant and pods per cluster at genotypic and phenotypic levels, while it had significant and positive phenotypic association with plant height and branches per plant. 80th genotypic and phenotypic correlations of pods p1ant⁻¹ with clusters p1ant⁻¹ and pods c1uster⁻¹ were significant and positive.
