Abstract: The experimental material comprised 22 greengram genotypes. The Observations were recorded on five randomly selected plants of each treatment and replication for 12 quantitative characters viz., days to 50% flowering, plant height (cm), number of branches per plant, number of clusters per plant, number of pods per plant, pod length (cm), number of seeds per pod, days to maturity, biological yield (g), harvest index, seed index (g), seed yield per plant (g) to estimate the genetic variability, heritability and correlations among yield and its related traits. Maximum GCV and PCV were recorded for no of branches/plant, pod length and harvest index. High heritability coupled with high genetic advance was registered for harvest index, pod length and seeds/pod. Correlation coefficient analysis revealed that seed yield per plant exhibited significant and positive correlation both at genotypic and phenotypic level with harvest index and biological yield/plant, Based on the results, KM 11-583XKM11-587 cross showed high mean performance for seed yield per plant. Heritability, genetic advance and correlation coefficient analysis indicated that these traits may be used for the development of higher grain yielding chickpea genotypes to improve yield of greengram. Hence, direct selection for these traits could be helpful in the improvement of greengram breeding.
