View the Complete Application at the US Patent & Trademark Office
A method is disclosed for producing a hybrid perennial plant system for plant breeding of co-sexual plants for increased yields and for having increased gene confinement capabilities. The method includes the steps of (a) contacting a first compatible perennial plant with a male vector, wherein the male vector comprises a SL expression cassette to create a plant line (A) with disrupted male development; (b) contacting a second compatible perennial plant with a female vector, wherein the female vector comprises a SL expression cassette to create a plant line (B) with disrupted female development; and (c) crossing plant line (A) with plant line (B) to produce the hybrid perennial plant having increased heterozygocity gene confinement.
