Climbing rose plant named ‘POULyc008’

Abstract

A new garden rose plant of the climber class which Has abundant, yellow-orange 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: ‘POULyc008’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant of the climber class, which originated from a controlled crossing between the female seed parent, an un-named seedling, and the male pollen parent ‘POULurt’, described and illustrated in U.S. Plant Pat. No. 9,637 dated Sep. 3, 1996. The two parents were crossed during the summer of 1992 and the resulting seeds were planted in a controlled environment in Fedensborg, Denmark. The new variety is named ‘POULyc008’.

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

• • 1. Flowers of the seed parent are more orange in color than flowers of ‘POULyc008’.
  • 2. The seed parent has larger leaves and leaflets than ‘POULyc008’.

The new variety may be distinguished from its male pollen parent, ‘POULurt’ by the following combination of characteristics:

• • 1. As the sepals divide, flower petals of ‘POULurt’ are Yellow-Orange Group 15A. Petals of ‘POULyc008’ are Orange-Red Group 32c to 34B.
  • 2. While the pollen parent ‘POULurt’ has a petal color, upon opening, of Yellow-Orange 15A at top ½ of petal with petal fading to Yellow-Orange Group 15C at base; the same of ‘POULyc008’ is Orange Group 24C with intonations of Yellow Group 11B.
  • 3. While the pollen parent ‘POULurt’ has a flower diameter of about 45 mm; the same characteristic of ‘POULyc008’ is 35 mm.

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 yellow-orange 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 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 ‘POULyc008’ 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 of 1991 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULyc008’ was selected in the spring of 1992 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULyc008’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in July, 1992. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULyc008’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULyc008’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 3 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 ‘POULhult’, a rose variety from the same inventors described and illustrated in U.S. Appl. No. 10/267,547 dated Oct. 8, 2002, are compared to ‘POULyc008’ in Chart 1.
