Reciprocal crosses of Upland cotton with a hybrid derived from ( Gossypium anomalum × G. thurberi ) × G. hirsutum produced progenies differing significantly in anther development and in the production of supernumerary ovules outside the ovary. Plants with G. anomalum cytoplasm produced fewer anthers than the reciprocal hybrids with G. hirsutum cytoplasm, had a higher percentage of sterile anthers, and were far more likely to form external ovules on an abnormally thickened tip of the staminal tube. The number of locules and ovules within the ovary was not significantly affected by cytoplasm.
