USPP15482P2 - Climbing rose plant named ‘POULyc007’ - Google Patents

Abstract

A new climbing garden rose plant which has abundant, pink 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: ‘POULyc007’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between a female parent ‘POULsint’, an unpatented variety, 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 is named ‘POULyc007’.

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

• • 1. The female parent has a flower diameter when open of less than 5 cm. ‘POULcy007’ has flowers which are 75 mm in diameter when open.
  • 2. While the seed parent has a narrow and bushy growth habit, ‘POULcy007’ has a climbing habit.

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

• • 1. The male parent has a flower petal color, on open flowers, upper surface of White Group 155D. ‘POULyc007’ has a flower petal color on open flowers, upper surface of Red Group 55C.
  • 2. General tonality of the pollen parent is opening are White Group 155B, while ‘POULyc007’ has a general tonality of Red Group 55D.

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, 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 distinguish ‘POULyc007’ 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.

‘POULyc007’ was selected in the spring 1995 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULyc007’ 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 ‘POULyc007’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULyc007’, as observed in its growth 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’, a rose variety from the same inventors described and illustrated in U.S. Plant patent application Ser. No. 10/341,890 and dated Jan. 13 , 2003, are compared to ‘POULyc007’ in Chart 1.
