| Abstract: |
A hybrid tea rose variety having nearly pure white buds and open flowers, long stems, few thorns and large disease 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 nearly pure white buds and open flowers, long stems, few thorns and large disease resistant foliage. |
| Description: |
This present invention relates to a new and distinct variety of rose plant of the hybridtea class which was originated by crossing the variety Coquette, U.S. Plant Pat. No. 4,019, with an unnamed variety.
The primary objective of this breeding was to produce a new rose variety suitable for use to produce cut blooms in greenhouses, of a white color, pointed bud form, attractive foliage. This objective was substantially achieved along with otherdesirable 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 of which I am aware:
1. Nearly pure white, pointed buds;
2. Long, rigid stems with few thorns;
3. Large, deep green, mildew resistant foliage;
4. Very slight 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:
