| Abstract: |
Miniature rose plant having high petal count of flowers of stable, red color; long shelf life as a pot rose; absence of pollen; and its ability to grow well on its own roots. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the miniature class, substantially as herein shown and described, characterized particularly by high petal count of flowers of stable, redcolor; long shelf life as a pot rose; absence of pollen; and its ability to grow well on its own roots. |
| Description: |
Genus and species: Rosa hybrida.
Variety denomination: `JACrepor`.
SUMMARY OF THE INVENTION
The present invention relates to a new and distinct variety of miniature rose plant named `JACrepor` which was originated by me by crossing the variety `KORstoffein`, U.S. Plant Pat. No. 11,242, with an unnamed seedling.
BACKGROUND OF THE INVENTION
The primary objective of this breeding was to produce a new rose variety having the high petal count, hard petals, and long shelf life of the female parent with the compact plant and red flower color of the 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. High petal count; 2. Stable red color; 3. Very long shelf life as pot rose; 4. Absence of pollen; 5. Ability to grow well on its own roots; and 6. Highly adaptability to grow in 10 cm pots.
Asexual reproduction of this new variety by rooting cuttings, as performed at Somis, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeedingpropagations.
Comparison with Parents
The female parent `KORstoffein` is a light pink pot rose with 2.5 cm flowers, the plant having a shelf life of about twenty-one days. The male parent has red, 6.5 cm flowers, the plant having a shelf life of about seven days.
Comparison with Similar Variety
`KORhomapo` (U.S. Plant Pat. No. 11,148) is a similar variety but possess dark red flowers of larger size but fewer petals and also bears longer leaves.
BRIEF DESCRIPTION OF THE ILLUSTRATION
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 (1966), except where ordinary dictionary significance of color isindicated. Parentage: Seed parent.--`KORstoffein` (U.S. Plant Pat. No. 11,242). Pollen parent.--Unnamed seedling. (Unpatented).
