SCIENTISTS at the Texas Agricultural Experiment Station have conducted extensive studies leading to the discovery of cytoplasmic-genetic male sterility in com (8) and sorghum (9, 10) and the development of methods and materials for using this type of sterility in commercial hybrid-seed programs. Researchers in cotton also have been interested in male sterility and have observed and analyzed a number of male-sterile stocks, none of which have proved to be of the cytoplasmic-genetic type. In 1940 Beasley (1, 2) observed that synthesized tetraploids of Gossypium arboreumy^G. thurberi were female fertile but usually male sterile. The early records, both published and unpublished, fail to establish which species contributed the cytoplasm. However, the synthesized amphi-
