Nineteen chickpea genotypes were evaluated to study genetic variability and phenotypic correlation between them for yield and yield components, at Shambat, the experimental farm, College of Agricultural studies, Sudan University of Science and Technology during two consecutive winter seasons of 2012/13 and 2013/14. A randomized complete block design with four replications was used in this study. Four characters were measured included Days to 50% flowering, number of pods/plant, 100 seed weight (gm) and seed yield/plant (Kg/ha). The estimates of phenotypic (PCV) and genotypic (GCV) Coefficients of variation, heritability (h2), genetic advance (GA%) were determined. The phenotypic correlation between yield and yield components was calculated. The results showed that there were highly significant differences between chick pea genotypes for all studied characters in both seasons. The highest values of phenotypic and genotypic coefficients of variation were scored by number pods per plant in both seasons. The highest values of heritability were scored by days to 50 % flowering and the lower values for 100- seed weight for both seasons. The highest value of heritability and genetic advance were observed for number of pods/plant in the second season. Seed yield /plant was positively and significantly correlated with number of pods per plant and hundred seed weight. Days to 50% flowering was negatively and significantly correlated with yield components. The chick pea genotype Salwa (released variety) obtained the most highest means of number of pods/plant, seed yield/plant and 100 seed weight in both seasons. The variation between chick pea genotypes observed in this study and the correlation results could of a great value in any chick pea breeding program in the Sudan.
