Floribunda rose plant named `POULsail`

Abstract

A new floribunda rose plant which has abundant, non-fading, salmon-orange 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 floribunda rose plant which originated from a controlled crossing between an unnamed seedling and an unnamed seedling. The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named `POULsail`.

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

1. The parents of the unnamed seedling are `POULgav` Gavno and RUImired, U.S. Plant Pat. No. 5,770.

2. The unnamed seedling has bronze colored flowers, while `POULsail` has salmon-orange flowers.

3. The unnamed seedling is slightly taller in height than `POULsail`.

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

1. The parents of the unnamed seedling are Crimson Midinette, RUImired, U.S. Plant Pat. No. 5,770 dated Jul. 22, 1986 and POULrouge, U.S. Plant Pat. No. 9,687 dated Nov. 12, 1996.

2. The unnamed seedling is a red miniature rose and `POULsail` is a salmon-orange floribunda.

3. The unnamed seedling has more compact growth and smaller foliage.

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 curttings in pots;

5. Durable flowers and foliage which make a variety suitable for distribution in the floral industry.

This combination of qualities was not present in previously available commercial cultivars in this market class and distinguish `POULsail` from all other varieties of which we are aware.

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.

`POULsail` was selected by the inventors as a single plant from the progeny of the hybridization in May, 1994.

Asexual reproduction of `POULsail` by cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in April, 1995. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of `POULsail` 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 `POULsail`. 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 description of `POULsail`, as observed in its growth in glasshouses in Fredensborg, Denmark and Half Moon Bay, Calif., and in a field nursery in Jackson County, Oreg. 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, several physical characteristics of the rose variety `POULrouge`, a patented rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 9,687 and issued on Nov. 12, 1996 are compared to `POULsail` in Chart 1.
