| Abstract: |
A hybrid tea rose variety having yellow blooms on long, straight stems, with glossy, mildew resistant foliage, and mild 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 long straight stems, glossy foliage, yellow buds and blooms with a moderate fragrance. |
| Description: |
This present invention relates to a new and distinct variety of rose plant of the hybrid tea classwhich was originated by me by crossing an unnamed variety, with the variety Sunshine, U.S. Plant Pat. No. 3,791.
The primary objective of this breeding was to produce a new rose variety suitable for the production of cut blooms when grown in a greenhouse, producing yellow blooms. This objective was substantially achieved along with other desirableimprovements 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 as from all other varieties of which I am aware:
1. A vigorous, upright plant producing straight stems of 18" to 24" length.
2. Pointed yellow buds opening to high centered blooms, fading only slightly in three or four days.
3. Glossy, mildew resistant foliage.
4. Mild fragrance.
Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.
Theaccompanying 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 color illustration of thischaracter.
The following is a detailed description of my new rose cultivar with color in terminology in accordance with the Royal Horticultural Society Colour Chart except where ordinary dictionary significance of color is indicated.
