Safflower ( Carthamus tinctorius L.) with appressed branches (angle with main stem is 20° or less and genotype apap ) was crossed to a type having decumbent branches (angle with main stem is 80 to 90° and genotype decdec ) to determine the association of the genes in inheritance and their combined effects on the phenotype. F 1 , F 2 , and F 3 populations were studied. The genes ap and dec were inherited independently. Because the genes had opposite effects on branching, the genotype apapdecdec had normal branching (angle with main stem is 40 to 70°).
