DEFINITION

Classification: 800/303

Male-sterile:

(under subclass 298) Subject matter wherein the higher plant, seedling, plant seed, or plant part is male-sterile.

(1) Note. A male sterile plant is one which produces no viable pollen. Male sterility prevents self pollination and the pollination of neighboring plants. These male sterile plants are therefore useful in hybrid plant production. The male sterile plant may still produce ova capable of being fertilized.
