| Abstract: |
A new miniature rose plant which has abundant, yellow flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year round production in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation. |
| Claim: |
It is claimed:
1. A new and distinct variety of rose plant named `Poulmist` of the miniature rose class, illustrated and described herein as a distinct and novel rose variety due to its abundantYellow Group 11C flowers, vigorous and compact growth, year round flowering under glasshouse conditions, suitability for production from softwood cuttings in pots, and durable flowers and foliage with an extended period of bloom. |
| Description: |
Botanical classification: Rosa hybrid.
Variety denomination: `Poulmist`.
SUMMARY OF THE INVENTION
The present invention constitutes a new and distinct variety of miniature rose plant which originated from a controlled crossing between an unnamed seedling and `POULjol`. The two parents were crossed and the resulting seeds were planted in acontrolled environment. The new variety is named `Poulmist`.
The new rose may be distinguished from its seed parent, an unnamed seedling, by the following characteristic: 1. The unnamed seed parent is a miniature rose variety with bi-color red and yellow flowers.
The new variety may be distinguished from its pollen parent, `POULjol`, a non-patented rose created by the same inventors, by the following combination of characteristics: 1. The pollen parent has blooms which are a more muted yellow than thatof `Poulmist's blooms. 2. The flowers of `Poulmist` have significantly better longevity than `POULjol`.
The objective of the hybridization of this rose variety for commercial culture was to create a new and distinct variety with unique qualities, such as: 1. Uniform and abundant flowers; 2. Vigorous and compact growth; 3. Year-round floweringunder glasshouse conditions; 4. Suitability for production from softwood cuttings in pots; 5. Durable flowers and foliage which make a variety suitable for distribution in the floral industry.
The combination of qualities of this variety represents significant improvement over previously available commercial cultivars of this type and distinguishes `Poulmist` from all other varieties of which we are aware.
As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.
`Poulmist` was selected by the inventors as a single plant from the progeny of the hybridization in May of 1997. Asexual reproduction of `Poulmist` by cuttings and traditional budding was first done by Mogens N. Olesen in Fredensborg, Denmark,in August of 1997. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of `Poulmist` are true to type and are transmitted from one generation to the next.
BRIEFDESCRIPTION OF THE DRAWING
The accompanying color illustration shows as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, flowers, leaves, stems, and a plant of `Poulmist`.
Specifically illustrated in SHEET 1: 1. Flowering stem showing branching and the attachment of leaves, buds, and peduncles; 2. Flower bud, partially opened bud, and open bloom; 3. Flower petals, detached; 4. Calyx; sepals detached; 5. Barestem and bare stem with leaf and bud; 6. Leaves.
DETAILED DESCRIPTION OF THE VARIETY
The following is a description of `Poulmist`, as observed in its growth in glasshouses in; Half Moon Bay, Calif. The observed plants were 75 days of age. Color references are made using The Royal Horticultural Society (London, England) ColourChart, 1995, except where common terms of color are used.
For a comparison, several physical characteristics of the rose variety `POULgelb`, a miniature rose variety from the same inventor, described and illustrated in U.S. Plant Pat. No. 9,401, are compared to `Poulmist ` in Table 1.
