D no longer is necessary in the production of hybrid corn seed for crosses involving female parents into which has been incorporated cytoplasmic male sterility. The most commonly used male-sterile cytoplasm is the Texas (T) type. Pollen production in the hybrid progeny is insured by using a male parent that carries restorer genes capable of restoring pollen fertility in the presence of this male-sterile cytoplasm. Since most Corn Belt inbred lines do not have the restorer genes, it has been necessary to incorporate them from other lines by backcrossing.
