The study was carried out at Agricultural Research Station, Tandur (PJTSAU) during Rabi, 2017-18 to determine genetic variability, heritability and genetic advance estimates in thirty genotypes of safflower. Analysis of variance involving a set of thirty genotypes of safflower for seven quantitative characters viz., days to 50% flowering, days to maturity, plant height, number of effective capitula/plant, number of seeds/capitulum, test weight (g) and seed yield (kg/ha) revealed highly significant mean sum of squares for all the characters indicating greater diversity among the genotypes. The genotypic coefficients of variation (GCV) for all the characters studied were lesser than the phenotypic coefficients of variation (PCV) indicating the effect of the environment. High GCV and PCV values were observed for seed yield, number of seeds per capitulum, number of effective capitula per plant and test weight. All the characters showed high estimates of heritability except plant height. High heritability coupled with high genetic advance as per cent of mean was observed for seed yield, number of seeds per capitulum, number of effective capitula per plant and test weight indicating the role of additive genes in governing the inheritance of these traits which could be improved through simple selection.
