Free branching poinsettia
Free branching poinsettia plants are provided which comprise a heritable lateral branching trait. In certain aspects, poinsettia plants comprising a lateral branching trait are not pinched, are not grafted and/or are free of phytoplasma infection. Methods for growth and breeding such free branching poinsettias are also provided.
1. A free branching poinsettia plant comprising a lateral branching trait wherein the plant is free of phytoplasma infection and any other branching agent, wherein the poinsettia plant is obtained by introgression of the lateral branching trait from a plant grown from the seed deposited at NCIMB under the accession no. NCIMB 41844, said plant having been selected for lateral branching.
2. The poinsettia plant of claim 1 , wherein the plant comprises 20 to 25 first branches.
3. The poinsettia plant of claim 1 , wherein said lateral branching trait confers at least one first branch and at least one second branch that extends from one of said at least one first branch.
4. The poinsettia plant of claim 3 , wherein said lateral branching trait confers one or more further branch(es), which extends from one of said one or more second branch or from another of said at least one further branch.
5. The poinsettia plant of claim 1 , further comprising at least one horticultural elite trait.
6. The poinsettia plant according to claim 5 , wherein said horticultural elite trait is selected from the group consisting of short stature, upright growth, strong branches, large blooms, large bracts, large inflorescences, vigorous growth, disease resistance, insect resistance, herbicide tolerance, increased longevity, midseason flowering, increased period of flowering, uniform plant habit, a desired leaf color or morphology, flower bracts with desirable colors and brilliant bract color.
7. A tissue culture of regenerable cells of the poinsettia plant of claim 1 , wherein said tissue culture of regenerable cells comprises said lateral branching trait.
8. A method of producing a free branching poinsettia plant comprising crossing a plant of claim 1 with a second poinsettia plant and selecting a progeny plant comprising the lateral branching trait.
9. A method for obtaining a the poinsettia plant according to claim 1 comprising the step of introgression of the lateral branching trait from a plant grown from the seed deposited at NCIMB under the accession no. NCIMB 41844.
