ABSTRACT:
BOTANICAL CLASSIFICATION
Rosa hybrida
‘POULra002’.
SUMMARY OF THE INVENTION
The present invention constitutes a new and distinct variety of miniature rose plant which originated from a controlled crossing between ‘POULhappy’ (U.S. Plant Pat. No. 9,483 dated Mar. 26, 1996) and ‘KORkleiva’ (U.S. Plant Pat. No. 11,232 dated Feb. 22, 2000). The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘POULra002’.
The new rose may be distinguished from its seed parent, ‘POULhappy’, by the following combination of characteristics:
1. The flower color of ‘POULhappy’ is red, whereas ‘POULra002’ is salmon orange.
2. The petalage of ‘POULhappy’ is semi-double whereas the petalage of ‘POULra002’ is double.
3. The size of the blooms of ‘POULhappy’ is smaller than ‘POULra002’.
The new variety may be distinguished from its pollen parent, ‘KORkleiva’ by the following combination of characteristics:
1. The color of ‘KORkleiva's’ blooms is creamy white, while the flower color of ‘POULra002’ is salmon.
2. The pollen parent has 1-3 blooms per flowering stem, whereas ‘POULra002’ has 3-5 blooms per flowering stem.
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 salmon 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 ‘POULra002’ 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 in winter 1997 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.
‘POULra002’ was selected by the inventors as a single plant from the progeny of the bybridization in spring 1998.
Asexual reproduction of ‘POULra002’ by cuttings and traditional budding was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in July, 1998. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULra002’ are true to type and are transmitted from one generation to the next.
