Inheritance of a completely branched (branches arise from 100% of the axial nodes) mutant was studied in safflower ( Carthamus tinctorit L.). Data from F 2 and F 3 progeny of a cross between a mutant and a tall‐branching cultivar (branches arise from 5 to 25% of the nodes) support the hypothesis that one completely dominant gene determines the incompletely branched habit; this gene is designated Cb . The double recessive cbcb determines the completely branched mutant. For the incompletely branched progeny, results suggest the presence of additional genetic variation for distribution of percentage of branching.
