Hybrid tea rose plant named ‘Poulren013’

Abstract

A new garden rose plant of the hybrid tea class 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 hybrid.

Variety denomination: ‘Poulren013’.

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between the female parent plant, a variety by the same inventors named ‘Poulsyng’, described and illustrated in U.S. Plant patent application Ser. No. 09/268,299 dated Mar. 16, 1999 (now abandoned), and the male parent, an unnamed seedling. The two parents were crossed during the summer of 1996 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘Poulren013’.

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

• • 1. Flower petal color of ‘Poulsyng’ is Red Group 36D, while ‘Poulren013’ is Red-Purple Group 65A to 65B.
  • 2. ‘Poulsyng’ has 34 to 40 petals ‘Poulren013’ normally has 50 petals.

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

• • 1. ‘Poulren013’ has Yellow basal petal spots, while the pollen parent has no distinctive coloration at the base of the petal.
  • 2. Flowers of the new variety have a much stronger fragrance than those of 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 pink flowers;
  • 2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;
  • 3. Disease resistance;
  • 4. Exceptional flower fragrance;
  • 5. Attractive, dark green foliage.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘Poulren013’ 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.

‘Poulren013’ was selected in the spring 1997 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulren013’ 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 ‘Poulren013’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulren013’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 3 years of age. Plants 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 characteristics of a Patented rose variety named ‘Wekuz’, described and illustrated in U.S. Plant Pat. No. 8,183 issued Mar. 23, 1993 are compared to ‘Poulren013’ in Chart 1.
