Abstract

A new climbing garden rose plant which has abundant, light pink and orange blend flowers and attractive foliage. 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: ‘POULyc005’.

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between a female parent ‘POULsint’, (unpatented), and the male parent, an unnamed plant. 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 was selected as a single plant from the controlled cross and is named ‘POULyc005’.

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

- 1. The female parent has very small flower size, less than 5 cm while ‘POULcy005’ has a flower size of 25-40 mm when open.
- 2. The female parent has narrow and bushy growth habit while ‘POULyc005’ has a broader climbing growth habit.

The new variety may be distinguished from its male parent, an unnamed plant, by the following combination of characteristics:

- 1. The male parent flower petal color, open flower, upper surface is White Group 155D. ‘POULyc005’ flower petal color, open flower, upper surface is Orange Group 27C with intonations of White Group 155B at basal zone.
- 2. The male parent has a wild rose scent; however, ‘POULyc005’ has a light floral scent.

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 light pink flowers.
- 2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots.
- 3. Disease resistance.
- 4. Improved flowering habit. Since the variety is less apically dominant than what is typical of climbing roses, flowers are produced evenly from the lower branches to the top.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguishes ‘POULyc005’ 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 during winter 1994 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULyc005’ was selected in the spring 1995 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULyc005’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in July, 1995. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULyc005’ 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 ‘POULyc005’. Specifically illustrated in THE DRAWING:

FIG. 1.1; Open flower and stem showing open flowers, the attachment of buds, and peduncles;

FIG. 1.2; Flower buds closed and partially open.

FIG. 1.3; Flower petals, detached;

FIG. 1.4; Sepals, receptacle, and pedicel;

FIG. 1.5; Mature leafs and juvenile leaf;

FIG. 1.6; Bare stem with thorns.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULyc005’, as observed in its growth in typical outdoor conditions in a field nursery in Jackson County, Oreg. Observed plants are 3 years of age. 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 ‘POULover’ (U.S. Plant patent application Ser. No. 10/341,890) are compared to ‘POULyc005’ in Chart 1.
