Novel indeterminate helianthus plant

Abstract

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.
