Abstract

A new miniature rose plant which has abundant, red 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: ‘POULpar029’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of miniature pot rose plant which originated from a controlled crossing between the female parent ‘KORstoffein’, described and illustrated in U.S. Plant Pat. No. 11,242 dated Feb. 22, 2000, and the male parent, an unnamed seedling. The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘POULpar029’.

The new rose may be distinguished from its seed parent. ‘KORstoffein’, by the following combination of characteristics:

- 1. ‘KORstoffein’ petals which are Yellow-Orange Group 19D. The same of ‘POULpar029’ are Red Group 53A.
- 2. ‘KORstoffein’ has a petal count of 25 to 30. ‘PUOLpar029’ has 30 petals.

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

- 1. The parent has a white flower color, whereas ‘POULpar029’ has a red flower color.
- 2. The parent plant has a petal count of 13 to 15, whereas the same of ‘POULpar029’ is 30.

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 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, known to the inventors, and distinguish ‘POULpar029’ 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.

‘POULpar029’ was selected by the inventors as a single plant from the progeny of the hybridization in 2000.

Asexual reproduction of ‘POULpar029’ by cuttings and traditional budding was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in 2001. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULpar029’ 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 ‘POULpar029’. Specifically illustrated in the drawing:

FIG. 1.1; Stem showing branching and the attachment of leaves, buds, and peduncles;

FIG. 1.2; Flower bud closed, partially open, and open;

FIG. 1.3; Flower petals, detached;

FIG. 1.4; Sepals, receptacle, and pedicel;

FIG. 1.6; Juvenile leaves exhibiting anthocyanin and mature leaves.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘PUOLpar029’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 3 months of age, and were cultivated in 10 cm pots. 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 ‘POULpar019’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 15,573 issued Feb. 22, 2005 are compared to ‘POULpar029’ in Chart 1.
