Numerous cotton hybrids–offspring of a cross between two individuals of dissimilar genetic constitution–have been produced in limited quantities for a plant breeding program at the Shafter Cotton Experiment Station.

Frank M. Eaton, Research Chemist in Soils and Plant Nutrition, University of California, Riverside, conducted the greenhouse experiments in 1955 at College Station, Texas.

R. J. Miravalle, Geneticist, and V. T. Walhood, Plant Physiologist, U.S.D.A. Cotton Field Station, Shafter, and Marvin Hoover, Extension Cotton Specialist, University of California, Shafter, participate in the continuing Hybrid Cotton Breeding Program.
