Data from S 1 , F 1 , F 2 , and BC 1 populations treated with the defoliant, Def, indicated that resistance to chemical defoliation in Upland cotton, Gossypium hirsutum L., was controlled at a single locus. The symbol df was assigned to the gene in question. Two phenotypes were recognized in the F 2 in the ratio of 3 susceptible ( Df —): 1 resistant to chemical defoliation ( dfdf ).
