| Abstract: |
A miniature rose variety characterized by the unique combination of its high production of light yellow buds on 12" to 14" stems, many of which are borne in clusters; its resistance to rose powdery mildew; its lack of fragrance. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the miniature class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of itshigh production of light yellow buds on 12" to 14" stems, many of which are borne in clusters; its resistance to rose powdery mildew; its lack of fragrance. |
| Description: |
This present invention relates toa new and distinct variety of rose plant of the miniature class which was originated by crossing the variety Rise 'n Shine, U.S. Plant Pat. No. 4,231, with an unnamed variety.
The primary objective of this breeding was to produce a new rose variety of the miniature class able to produce vigorous, dense growth, and an abundance of long-pointed yellow buds on stems suitable for cut flower use. This objective wassubstantially 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 as from all other varieties ofwhich I am aware:
1. Vigorous miniature plant up to 24" in height outside, approximately 48" to 60" in greenhouse;
2. Cutting stems mostly 12" to 14" in length;
3. Frequent production of clusters of 4 to 6 buds;
4. Light yellow buds and open blooms;
5. Strong resistance to rose powdery mildew;
6 Relatively long, but few prickles.
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:
