| Abstract: |
A Grandiflora class rose plant having vigorous upright habit of growth, non-fading yellow flowers, resistance to rust, tolerance to blackspot, and high production of flowers suitable for cutting from the garden. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the Grandiflora class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination ofits vigorous, upright growth habit, bright, non-fading yellow flowers, resistance to rust, tolerance to blackspot, and high production of flowers suitable for cutting from the garden. |
| Description: |
Thepresent invention relates to a new and distinct variety of rose plant of the Grandiflora class which was originated by me by crossing the variety Sunbright, U.S. Plant Pat. No. 4,438, with the variety Sunflare, U.S. Plant Pat. No. 5,001.
The primary objective of this breeding was to produce a new rose variety having the excellent color stability and flower form of Sunbright combined with the very heavy flower production and disease resistance of Sunflare. The 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, upright habit of growth.
2. Non-fading yellow flower.
3. Resistance to rust and tolerance to blackspot.
4. High production of flowers suitable for cutting from the garden.
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 description using terminology in accordance with the Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of coloris indicated.
