ABSTRACT:
A process is described for producing fertile hybrid seed or hybrid seed comprising fertile and sterile seed using male-sterile plants created by employing molecular techniques to manipulate genes that are capable of controlling the production of fertile pollen in plants. Hybrid seed production is simplified and improved by this approach, which can be extended to plant crop species for which commercially acceptable hybrid seed production methods have not been available.
