Abstract

A new garden rose plant of the climbing rose class which has abundant, red flowers and attractive, dark, glossy foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Description

Botanical classification: Rosa hybrid.

Variety denomination: ‘Poulcy012’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant that originated from a controlled crossing between the female seed parent ‘Kormixal’, an unpatented variety, and the male pollen parent, an un-named seedling from the same inventors.

The two parents were crossed during the summer of 1994 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘Poulcy012’.

The new variety may be distinguished from its female seed parent, ‘Kormixal’ by the following combination of characteristics:

- 1. ‘Poulcy012’ is taller than the seed parent.
- 2. ‘Kormixal’ has fewer flower petals than ‘Poulcy012’.
- 3. ‘Kormixal’ has smaller flowers than ‘Poulcy012’.

The new variety may be distinguished from the male pollen parent by the following combination of characteristics:

- 1. The pollen parent has light pink flowers while ‘Poulcy012’ has medium red flowers.
- 2. ‘Poulcy012’ produces a greater quantity of flowers than the pollen parent.

The objective of the hybridization of this rose variety was to create a new and distinct variety for garden use with unique qualities, such as:

- 1. Uniform and abundant medium red flowers;
- 2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;
- 3. Disease resistance.
- 4. Reduced apical dominance in flowering habit. The new variety consistently produces flowers evenly from the lower branches to the top of the plant.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘Poulcy012’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 1996 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘Poulcy012’ was selected in the spring of 1997 by the inventor as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulcy012’ by traditional budding and rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July 1997. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulcy012’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulcy012’, as observed in its growth in in a field nursery in Jackson County, Oreg. Observed plants are 2 years of age, and were grown on Rosa multiflora understock. 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 ‘Poulyc009’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 15,411 issued on 7 Dec. 2004, are compared to ‘Poulcy012’ in Chart 1.
