chickpea genotypes, Genetic variability, Uttar Pradesh.

The present studies were conducted to the estimation of correlation for quantitative traits in chickpea (Cicer arietinum L.) in the field of the department of Genetics and Plant Breeding, Janta Vedic College, Baraut Baghput (U.P.) during the crop season 2003 to 2004 under rainfed condition. The present investigation revealed that the maximum days to maturity (151) were recorded in BG 1107 and Pusa 1063, whereas three genotypes (Pusa 209, BG 2002 and Pusa 1090) took minimum days (136) to mature. There was a great variation in biological yield among genotypes that ranged from 19.43 g to 36.83 g. Number of branches ranged from 9.37 to 15.33. Number of pods plant-1 varied from 45.53 to 68 and BG 1105 exhibited maximum number of pods (68). The variation for 100-seed weight ranged from 17.05 g to 32.31 g. The highest seed yield plant-1 was recorded for genotype BG 2002 (12.68 g), Pusa 362 (12.73g) and AT-2-1184 showed minimum seed yield (7.83 g). High heritability estimates were observed for number of branches (88.12), protein content (78.65), number of pods per plants, harvest index plant height and biological yield. High heritability coupled with high genetic advance for number of branches per plant, harvest index, pods per plant, 100-seed weight and biological yield. High heritability with low genetic advance was observed for protein content plant height. Seed yield per plant showed positive and significant phenotypic correlation with number of branches, number of pods per plant, biological yield per plant, 100-seed weight and harvest index. Cluster I, VII, III and VI, respectively possessed 12, 10, 6 and 5 genotypes. Means of various traits for each character showed that genotypes with maximum number of branches, pods per plant, 100-seed weight biological yield and seed yield per plant were placed together in cluster II. Genotypes with maximum harvest index were placed in cluster VI and genotypes with maximum days to maturity were placed in cluster VII.
