NOVEL INDETERMINATE HELIANTHUS PLANT
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 comprising a genetic determinant responsible for an indeterminate phenotype.
2 . The interspecific Helianthus plant of claim 1 , obtainable by crossing a Helianthus plant with another Helianthus plant comprising a genetic determinant responsible for an indeterminate phenotype, wherein a sample of representative seed of said plant comprising a genetic determinant responsible for an indeterminate phenotype is deposited under NCIMB Accession No. 42200.
3 . The interspecific Helianthus plant of claim 1 , wherein said genetic determinant responsible for an indeterminate phenotype can be found in a plant grown from seed deposited under NCIMB Accession No. 42200.
4 . The interspecific Helianthus plant of claim 1 wherein said plant is made from H. annuus and H. argophyllus.
5 . Helianthus seed comprising a genetic determinant responsible for an indeterminate phenotype, wherein said seed is obtainable from a plant according to claim 1 .
6 . A Helianthus plant produced by growing the seed of claim 5 .
7 . A method of producing hybrid Helianthus seed according to claim 5 comprising crossing a first parent Helianthus plant with a second parent Helianthus plant and harvesting the resultant F 1 hybrid Helianthus seed.
8 . Hybrid seed produced by the method of claim 7 .
9 . A hybrid plant or its parts produced by growing the hybrid seed of claim 8 .
10 . Seed comprising a genetic determinant responsible for an indeterminate phenotype produced from the hybrid plant of claim 9 .
11 . Viable Helianthus seed deposited under NCIMB Accession No. 42200 and plants grown from said deposited seed or the progeny thereof, wherein the progeny contain a genetic determinant for the indeterminate phenotype.
