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 anti-sense gene and other genes that are capable of controlling the production of fertile pollen in plants. Said plants are functionally male-sterile plants with pollen from male-fertile plants. Hybrid seed production is simplified and improved by this invention and can be extended to plant crop species for which commercially acceptable hybrid seed production methods are not currently available.
Claims16
An isolated recombinant DNA molecule comprising:
- (a) a DNA sequence which encodes an antisense RNA which is antisense to a sense gene essential to pollen formation or function;
- and
- (b) a promoter capable of causing the transcription of said DNA sequence.
