Inheritance of a Completely Branched Mutant in Safflower1

  1. G. H. Abel2

Abstract

Abstract

Inheritance of a completely branched (branches arise from 100% of the axial nodes) mutant was studied in safflower (Carthamus tinctorit L.). Data from F2 and F3 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.
