Abstract: Practically no molecular tools have been developed so far for safflower (Carthamus tinctorius L.) breeding. The objective of the present research was to develop molecular markers for the closely linked genes Li, controlling very high linoleic acid content, and Ms, controlling nuclear male sterility (NMS). A mapping population of 162 individuals was developed from the NMS line CL1 (64–79% linoleic acid) and the line CR-142 (84–90%), and phenotyped in the F2 and F3 generations. Bulked segregant analysis with random amplified polymorphic (RAPD) markers revealed linkage of five RAPD bands to the Li and Ms genes. RAPD fragments were converted into sequence-characterized amplified region (SCAR) markers. A linkage map including the five SCAR markers and the Li and Ms genes was constructed. SCAR markers flanked both loci at minimum distances of 15.7 cM from the Li locus and 3.7 cM from the Ms locus. These are the first molecular markers developed for trait selection in safflower.
