| Abstract: |
Minature rose with yellow-orange blossom petals having red stripes which spread as blossom ages. Plant is resistant to rust and powdery mildew. Rose is cross of variety AROgobi with the variety MORprints. |
| 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 itsnovel striping and color change in the flower, the presence of glands on the stipules, peduncle, petiole and rachis, its resistance to powdery mildew and rust, its upright but dwarf growth habit and its dark green glossy foliage. |
| Description: |
The present invention relates to a new and distinct variety of rose plant of the miniature class which was originated by me by crossing the variety AROgobi, U.S. Plant Pat. No. 5,702, with the varietyMORprints.
The primary objective of this breeding was to produce a new rose variety having the gold yellow colour and dark green foliage of the variety AROgobi combined with the compact habit and flower striping of the variety MORpints. 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. Unusual striping in the flower and a gradual spread of the red color in the flower as it ages.
2. Resistance to powdery mildew and rust
3. Dark green glossy foliage
4. Upright but dwarf habit of growth
5. Abundance of glands on stipules, sepals, peduncle and petiole.
Asexual reproduction of this new variety by budding and by softwood cuttings, as performed at Wasco and Somis, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted throughsucceeding propagations.
The accompanying photograph 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 thesame in a color illustration 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 whereordinary dictionary significance of color is indicated.
Parentage:
Seed parent.--AROgobi.
Pollen parent.--MORpints.
