Hybrid Cotton Planting Seed

Dick Crill


A technique has been developed for the production of F1 Hybrid cotton planting seed. This technique uses a system of facultative pollen self-incompatibility where two different types of cotton cross-pollinate each other. At anthesis self-pollination occurs, but fertilization from the self-pollination is delayed due to facultative self-incompatibility. This time delay allows for cross-pollination and cross fertilization to take place before self-fertilization can be achieved. In the absence of cross fertilization, self-fertilization takes place thirty-six to forty-eight hours after anthesis. Hybrid cotton planting seed can be produced by mixing together two different facultative self-incompatible cotton lines and producing the crop with a continuous and abundant supply of cotton pollinating insects. The seed resulting from the cross pollinations during this crop production is Fl hybrid cottonseed.
