Abstract
Methods are disclosed for rendering cotton plants male sterile through application of isothiazole plant growth regulators without causing substantial female sterility or loss of reproductive vigor. Processes for effecting the hybridization of cotton employing monitoring of the degree of burning of cotton bracts are presented. More particularly, male sterility is attained by the application of potassium 3,4-dichloroisothiazole-5-carboxylate to cotton plants in an amount sufficient to cause finger burning of the bracts without causing excess burning thereof. Hybridization is attained by exposing male sterile plants in accordance with the foregoing processes to pollen from plants of differing varieties of cotton.
