Abstract

A new miniature rose plant which has abundant, creamy white 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

Botanical classification: Rosa hybrida.
Variety denomination: ‘POULra017’.
SUMMARY OF THE INVENTION
The present discovery constitutes a new and distinct variety of a miniature pot rose plant which was discovered in a cultivated area. The mutation resulted from ‘POULra002’, a miniature pot rose hybridized by the same inventors. ‘POULra002’ is described and illustrated in U.S. Plant Pat. No. 13,275, and issued on Nov. 26, 2002. The new rose variety resulted from a naturally occurring mutation of unknown causation on a branch of ‘POULra002’.
The new variety may be distinguished from its parent variety ‘Poulra002’ by the following combination of characteristics:
1. While flowers of the parent variety have 35 to 45 petals, ‘Poulra017’ has an average of 50 flower petals.
2. While the open flowers of the parent variety have a general tonality of Red Group 43C, ‘Poulra017’ is Yellow-Orange Group 19D.
3. While the styles, on reproductive flower parts of the parent variety are Yellow-Green Group 145B in color, ‘Poulra017’ is Red-Purple Group 196C.
The rose plant of the present discovery has a unique combination of characteristics which are outstanding in the new variety and which distinguish it from the original rose ‘POULra002’, as well as all other varieties which we are aware of. For example, the new variety has:
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.
This combination of qualities is not present in previously available commercial cultivars of this type and distinguish ‘POULra017’ from all other varieties of which we are aware.
The resulting mutation was selected and evaluations were conducted on the resulting rose plants in a controlled environment. Asexual reproduction of ‘POULra017’ by cuttings and traditional budding was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in 1977. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULra017’ 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, and stems of ‘POULra017’. Specifically illustrated in FIG. 1:
FIG. 1.1; Stem showing branching and the attachment of leaves, buds, and peduncles;
FIG. 1.2; Flower bud, partially opened bud, and open bloom;
FIG. 1.3; Flower petals, detached;
FIG. 1.4; Sepals, receptacle, and pedicel;
FIG. 1.5; Stem as well as a bare stem exhibiting thorns;
FIG. 1.6; Leaves.
DETAILED DESCRIPTION OF THE VARIETY
The following is a description of ‘POULra017’, as observed in its growth in a field nursery in Jackson County, Oreg. in February of 2003. 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 ‘POULra015’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 14,309, issued on Nov. 18, 2003 are compared to ‘POULra017’ in Chart 1.
