Abstract
Twenty-one chickpea genotypes were tested to evaluate genetic variation in some agronomic traits, heritability and genetic advance. The experiment was conducted in field crops during the 2018 -2019 growing season. A Randomized Complete Block Design (CRD) with three replications was used; data were collected for days to 50% flowering, plant height, number of primary branches per plant, number of secondary branches per plant, the height of the first pod from the ground, number of pods per plant, number of seeds per pod, biological yield per plant, seed yield per plant, harvest index and 100-seed weight. Analysis of variance showed a highly significant mean square difference for all traits except the number of pods per plant, harvest index and 100-seed weight. Genotypes (7,18) were more distinctive than the other genotypes in most characteristics. The high value of the genotypic coefficient of variation was found for biological yield per plant (29. 772), seed yield per plant (24.757) and the number of primary branches (24.849). High heritability was recorded for the first pod height from the ground (67.8) and plant height (60.8). High expected genetic advance as a percentage of the mean was estimated for biological yield per plant (41.144), seed yield per plant (39.61), and the number of primary branches per plant (38.382).
