| Abstract: |
Hybrid tea rose plant having exceptionally rich apricot blooms; compact well-branched hybrid tea plant habit; ability to grow vigorously on its own roots; resistance to powdery mildew and rust; large open flowers; and glossy, dark green 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 by its exceptionally rich apricot blooms; compact well-branched hybrid tea plant habit; ability to grow vigorously on its own roots; resistance to powdery mildew and rust; large open flowers; and glossy, dark green foliage. |
| Description: |
Genusand species: Rosa hybrida.
Variety denomination: `JACurnam`.
ORIGIN OF THE INVENTION
The present invention relates to a new and distinct variety of a hybrid tea rose plant named `JACurnam` which was originated by me by crossing the variety `JACient` (U.S. Plant Pat. No. 6,725), with an unnamed seedling (not patented).
BACKGROUND OF THE INVENTION
The primary objective of this breeding was to produce a new rose variety having the profuse flowering, excellent high disease resistant foliage, and vigorous growth of the female parent combined with the strong growth and disease resistance ofthe unnamed yellow hybrid tea male parent.
BRIEF SUMMARY OF THE INVENTION
The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well asfrom all other varieties of which I am aware: 1. Exceptionally rich apricot blooms. 2. Compact, well branched hybrid tea plant. 3. Ability to grow vigorously on its own roots. 4. Resistance to powdery mildew and rust. 5. Large open flower. 6. Glossy, dark green foliage.
Asexual reproduction of this new variety by cuttings, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.
COMPARISON WITH PARENTS
The subject variety differs in that the female parent has a pink flower coloring versus the rich apricot, clustering ability of `JACurnam` (grandiflora versus hybrid tea). The male parent differs in flower color (yellow versus rich apricot) andflower size (9 cm versus 13 cm).
COMPARISON WITH SIMILAR VARIETY
The subject variety differs from Medallion in having a deeper apricot flower color, much shorter plant (150 cm versus 180 cm) than Medallion and a smaller flower size than Medallion (13 cm versus 15 cm).
BRIEF DESCRIPTION OF THEILLUSTRATION
The accompanying 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 colorillustration of this character.
DETAILED BOTANICAL DESCRIPTION
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 (2001), except where ordinary dictionary significance of color isindicated. Parentage: Seed parent.--`JACient` (U.S. Plant Pat. No. 6,725). Pollen parent.--Unnamed seedling, (Not patented) (unnamed seeding.times.unnamed seedling).
Observations made from plants commencing at two years of age grown in a garden environment at Somis, Calif.
FLOWER Blooming habit: Continuous. Bud: Size.--About 4 cm long and 3.5 cm in diameter when the petals start to unfurl. Form.--The bud form is long, pointed ovoid.
