Abstract (en)

[origin: WO9710703A1] Fertility can be restored to certain male-sterile plants by exogenous jasmonate or a related compound. Methods are disclosed for identifying and producing "conditionally male-fertile" plants are produced by mutations that interfere with normal jasmonic acid metabolism. The ability to produce and/or identify conditionally male-fertile plants and to rescue the fertility of these plants by simple application of a chemical compound forms the basis for a conditional male-fertility system that is broadly applicable to hybrid breeding of crop and horticultural plants.
