USPP11514P - Miniature rose plant named `POULody`. - Google Patents

Abstract

A new miniature pot rose plant which has abundant, non-fading, lavender-pink 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.

Description

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 `POULpol`. The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named `POULody`.

The new rose may be distinguished from its seed parent, an unnamed seedling by the same inventors, by the following combination of characteristics:

1. `POULody` has lavender-pink flowers, while the unnamed seedling has bluish-red flowers.

2. The parents of the unnamed seedling are `Mainzer Fastnacht`, a lavender hybrid tea and RUImired, U.S. Plant Pat. No. 5,770, a red miniature rose variety.

The new variety may be distinguished from its pollen parent, `POULod` created by the same inventors, by the following combination of characteristics:

1. Flowers of `POULody` have better lastingness.

2. `POULody` has lavender-pink flowers while `POULpol` has soft pink flowers.

3. `POULodyl` has larger, but fewer flowers than `POULpol`.

4. `POULpol` is more compact.

The objective of the hybridization of this rose variety for commercial greenhouse 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 flowering under 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.

As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen germinated the seeds from the aforementioned hybridization and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

`POULody` was selected by the inventors as a single plant from the progeny of the hybridization in April, 1995.

Asexual reproduction of `POULody` by cuttings and traditional budding was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in September, 1995. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of `POULody` are true to type and are transmitted from one generation to the next.

BRIEF DESCRIPTION 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 `POULody`. Specifically illustrated in SHEET 1:

1. Stem or entire plant showing branching and the attachment of leaves, buds, and peduncles;

2. Flower bud, partially opened bud, and open bloom;

3. Flower petals, detached;

4. Sepals, receptacle, and pedicel;

5. Flowering stem as well as a bare stem exhibiting thorns;

6. Leaves.

DETAILED DESCRIPTION OF THE VARIETY

The following is a detailed description of `POULody`, as observed in its growth in glasshouses in Fredensborg, Denmark and Half Moon Bay, Calif. and in field nursery in Jackson County, Ore. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 1995, except where common terms of color are used.

For a comparison, the nearest existing rose variety is `POULprima`, a patented variety by the same inventors described and illustrated in U.S. Plant Pat. No. 9,482 and issued on Mar. 26, 1996. Chart 1 details several physical characteristics of `POULody` and `POULprima`.
