Abstract
The present invention relates to intergeneric hybrid plants of Zinnia elegans and Tagetes erecta and methods for making the same. The invention further relates to methods for producing intergeneric hybrid plants of Z. elegans and T. erecta containing in their genetic material one or more transgenes and the intergeneric hybrid plants produced by that method. The invention also relates to transferring desirable characteristics from one genera to the other, as well as creation of new unique characteristics not found in either of the parent genera alone. The invention further relates to methods for producing intergeneric hybrid plants of Z. elegans and T. erecta derived from intergeneric hybrid plants of Z. elegans and T. erecta and to the plants produced by the method.
Claims10
An intergeneric hybrid plant of Zinnia elegans and Tagetes erecta having a powdery mildew expression rating of at least 3.5 on a scale of 1 to 5 where 5 is the least mildew and that flowers 1-2 weeks earlier than the Z. elegans parent plant and the T. erecta parent plant.
A method of producing an intergeneric hybrid plant of Z. elegans and T. erecta having a powdery mildew expression rating of at least 3.5 on a scale of 1 to 5 where 5 is the least mildew and that flowers 1-2 weeks earlier than the Z. elegans parent plant and the T. erecta parent plant comprising:
- (a) selecting a first plant of Z. elegans or T. erecta to use as the female parent and a second plant of the other genera to use as the male parent;
- (b) collecting pollen from open flowers on the male parent;
- (c) applying the pollen to receptive female flowers on the female parent indicated in the cross to produce intergeneric hybrid seed;
- (d) harvesting intergeneric hybrid seed of Z. elegans and T. erecta;
- and
- (e) growing and selecting said intergeneric hybrid seed of Z. elegans and T. erecta to produce an intergeneric hybrid plant of Z. elegans and T. erecta having a powdery mildew expression rating of at least 3.5 on a scale of 1 to 5 where 5 is the least mildew and that flowers 1-2 weeks earlier than the Z. elegans parent plant and the T. erecta parent plant.
A method of producing an intergeneric hybrid plant of Z. elegans and T. erecta having a powdery mildew expression rating of at least 3.5 on a scale of 1 to 5 where 5 is the least mildew and that flowers 1-2 weeks earlier than the Z. elegans parent plant and the T. erecta parent plant comprising:
- (a) selecting a plant of Z. elegans or T. erecta to use as the female parent and a plant of the other genera to use as the male parent in a cross;
- (b) collecting pollen from open flowers on the male parent;
- (c) applying the pollen to receptive female flowers on the female parent indicated in the cross;
- (d) isolating an embryo resulting from the cross by embryo rescue;
- and
- (e) growing and selecting said embryo to obtain an intergeneric hybrid plant of Z. elegans and T. erecta having a powdery mildew expression rating of at least 3.5 on a scale of 1 to 5 where 5 is the least mildew and that flowers 1-2 weeks earlier than the Z. elegans parent plant and the T. erecta parent plant.
