Cultivated cottons have small, pigment‐bearing glands in their embryonic tissues or seed meats. These glands contain gossypol, a polyphenolic substance toxic to various animals. The presence of glands in cottonseed is controlled by alleles at two loci. Substitution of mutant alleles for active alleles at both loci produce cottons that are devoid of glands and gossypol. Glandlessness is thus a character of great potential worth, and breeders seek to develop glandless varieties of cotton which give high yields of quality fiber. Although some success has been achieved, recent work shows that both glandless genes are linked to factors which reduce yield of fiber. Methods for ameliorating these difficulties are discussed.
