| Abstract: |
A hybrid tea rose plant characterized particularly as to novelty by the unique combination of its large, light yellow flowers; its vigorous, upright habit of growth; its good production of long, straight stems; its strong fragrance; and its dark green, powdery mildew resistant foliage. |
| 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 large, light yellow flowers; its vigorous, upright habit of growth; its good production of long, straight stems; its strong fragrance; and its dark green, powdery mildew resistant foliage. |
| Description: |
The present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by me by crossing the variety JACblem, U.S. Plant Pat. No. 4,847 with the variety JACliow, unpatented.
The primary objective of this breeding was to produce a new rose variety having the dark green glossy foliage and powdery mildew resistance, the high production and yellow color of the female parent combined with the good production and largeflower size of the male parent. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it fromits parents, as well as from all other varieties of which I am aware:
1. Large, light yellow flowers.
2. Strong, musky fragrance.
3. Vigorous, upright habit of growth.
4. Good production of long, strong stems.
5. Dark green, glossy, mildew resistant foliage.
Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.
The accompanying illustration 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.
