Abstract
In this study; the responses of 12 safflower genotypes to anther culture were determined in MS medium containing increasing doses of BAP (0, 0.5, 1, and 2 mg L-1) and NAA (0, 0.1, and 0.5 mg L-1). Donor plants were grown under field conditions and the main capitulas were collected in early or late uninucleate stage. A pre-treatment was applied to their capitules at +4 °C for 3-4 days. Only cvs. Balcı and Linas produced regenerable callus among these genotypes. Although regenerable callus rate was higher in Balcı than Linas, shoot regeneration was achieved only in Linas with 0.5 or 1 mg L-1 of BAP + 0.1 mg L-1 of NAA combinations. In total, 8 shoots of Linas were moved to ½ MS medium consisting of 0.1 mg L-1 of NAA, but rooting of them could not be performed. In sum, among the 12 safflower genotypes, cvs. Balcı and Linas have higher anther culture regeneration potential; however, it is necessary to focus on shoot development and rooting on these cultivars in further experiments.
