Indeterminate
The present invention provides an interspecific Helianthus plant comprising a genetic determinant responsible for an indeterminate phenotype. Methods of making said plant are also provided.
1. An interspecific Helianthus plant designated SUO22=SUL1 representative seed deposited under NCIMB Accession No. 42200.
2. The interspecific Helianthus plant of claim 1 wherein said plant is made from H. annuus and H. argophyllus.
3. A method of producing hybrid Helianthus seed comprising crossing a first parent Helianthus plant with a second parent Helianthus plant and harvesting the resultant hybrid Helianthus seed, wherein the first parent Helianthus plant or the second parent Helianthus plant is the plant of claim 1 .
4. A hybrid Helianthus seed produced by the method of claim 3 , wherein the female parent is the interspecific Helianthus plant designated SUO22=SUL1.
5. A method of producing a hybrid Helianthus plant or its parts, said method comprising growing a hybrid seed produced by the method of claim 3 .
6. A viable Helianthus seed designated SUO22=SUL1 deposited under NCIMB Accession No. 42200.
