Abstract:
The field experiment was carried out at All India Co-ordinated Research Project on Safflower, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during Rabi-2019-20 to evaluate the genetic variability, heritability and genetic advance estimates in sixty two genotypes along with two local checks PBNS-12 and A-1 of safflower. Analysis of Variance involving 64 genotypes of safflower for eleven quantitative characters viz., days to 50% flowering, days to maturity, plant height (cm), number of primary branches per plant, number of secondary branches per plant, number of effective capitula/plant, number of seeds per capitulum,100-seed weight (g), seed yield per plant (g), hull content (%) and oil content (%) revealed highly significant mean sum of squares for all the characters indicating greater diversity among the genotypes. Phenotypic coefficient of variation was higher in magnitude than the genotypic coefficient of variation in respect of all the characters indicating the effect of the environment. Number of secondary branches per plant, seed yield per plant, number of primary branches per plant, number of effective capitula per plant, number of seeds per capitulum shown high phenotypic and genotypic coefficient of variation. Heritability in broad sense were higher for almost all the characters except hull content and oil content. High heritability coupled with high genetic advance as percent of mean was observed for number of secondary branches per plant followed by seed yield per plant, number of seeds per capitula, number of primary branches/plant, number of effective capitula per plant, plant height, 100-seed weight indicating the role of additive genes in governing the inheritance of these traits which could be improved through simple selection.
