| Abstract: |
A hybrid tea rose created by crossing an unnamed seedling with the variety JACjel, U.S. Plant Pat. No. 4,438, is characterized by the change in its abundant flowers from bright yellow to red as the flower matures, the presence of glands on the peduncles, sepal and stipules and its pleasant, moderate fragrance. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination ofits dramatic flower color change from yellow to red, the presence of glands on peduncles, sepals and stipules, its abundance of flowers and its pleasant fragrance. |
| Description: |
The present invention relatesto a new and distinct variety of rose plant of the hybrid tea class which was originated by me by crossing the variety an unnamed seedling, with the variety JACjel, U.S. Plant Pat. No. 4,438.
The primary objective of this breeding was to produce a new rose variety having the strong upright growth and orange and yellow flower color of the unnamed seedling combined with the large flowers and heavy flowering of the yellow hybrid teaJACjel. The objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well asfrom all other varieties of which I am aware:
1. Bright yellow changing to red as the flower matures;
2. Presence of glands on peduncles, sepals and stipules;
3. Pleasant, moderate fragrance;
4. Abundance of flowers.
Asexual reproduction of this new variety by budding, as performed at Wasco and Somis, Calif. shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.
The accompanying photograph shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a colorillustration of this character.
The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionarysignificance of color is indicated.
