ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Poinsettia plant, botanically known as
Euphorbia pulcherrima
Willd., and hereinafter referred to by the name ‘Jacabia’.
The new Poinsettia is a product of a mutation induction breeding program conducted in Skibby, Denmark. The objective of the program is to create new Poinsettia cultivars having interesting bract and leaf display, desirable bract and foliage color and form, strong and freely branching stems and good post-production longevity.
The new Poinsettia originated by exposign unrooted cuttings of the commercial
Euphorbia pulcherrima
Willd. cultivar 490, disclosed in U.S. Plant Pat. No. 7,825, to gamma-ray radiation. The new Poinsettia was discovered and selected in December, 1995 in Encinitas, Calif. The selection of this plant was based on its unique bract shape.
Asexual reproduction of the new Poinsettia by terminal cuttings taken at Encinitas, Calif., has shown that the unique features of this new Poinsettia are stable and reproduced true to type in successive generations of asexual reproduction.
BRIEF SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Jacabia’. These characteristics in combination distinguish ‘Jacabia’ as a new and distinct cultivar:
1. Unique narrowly ovate red-colored bracts that are held somewhat upright.
2. Unique narrowly ovate dark green leaves.
3. Compact plant habit and short internodes.
4. Late flowering, response time about 10 weeks.
5. Excellent postproduction longevity.
In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of the parent cultivar, 490, in the following characteristics:
1. Plants of the new Poinsettia are shorter, more compact and less vigorous than plants of ‘490’.
2. Plants of the new Poinsettia are not as freely branching as plans of ‘490’.
3. Leaves of the new Poinsettia are smaller, narrower, more acuminate and lighter green than leaves of ‘490’.
4. Petioles of the new Poinsettia are shorter than petioles of ‘490’.
5. Plants of the new Poinsettia have much smaller inflorescences than plants of ‘490’.
6. Bracts of the new Poinsettia are more upright, smaller, narrower and more acuminate than bracts of ‘490’.
7. Bract color of the new Poinsettia is more crimson than bract color ‘490’.
8. Plants of the new Poinsettia flower about 10 to 14 days later than plants of ‘490’.
