Abstract

A new garden rose plant of the hybrid tea class which has abundant, light 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: ‘POULpm001’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between the unnamed female parent plant and the male parent ‘POULdrik’, described and illustrated in U.S. Plant Pat. No. 12,557 issued Apr. 23, 2002. The two parents were crossed during the summer of 1991 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULpm001’.

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

- 1. While the seed parent has dark pink flowers. ‘POULpm001’ is light pink.
- 2. While the seed parent has a short growth height, less than 60 cm in height, ‘POULpm001’ is 60 to 100 cm in height.
- 3. While the seed parent develops single flower buds per flowering stem, ‘POULpm001’ will develop 1 to 3 flower buds per flowering stem.

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

- 1. While the pollen parent ‘POULdrik’ has a petal color, as the sepals unfold, of Red Group 46D, the same of ‘POULpm001’ is Yellow-Green Group 145C.
- 2. While the pollen parent ‘POULdrik’ has a sepal size of 15 mm long and 10 mm wide the same of ‘POULpm001’ are larger, measuring 30 mm long and 12 mm wide.
- 3. While the pollen parent ‘POULdrik’ has a general tonality of Red Group 64D. ‘POULpm001’ has a general tonality of Red Group 36A to 36D.

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;
- 4. Good branching habit;
- 3. Disease resistance.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘POULpm001’ 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.

‘POULpm001’ was selected in the spring 1992 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULpm001’ 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 ‘POULpm001’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULpm001’, 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 root stock. 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 ‘POULasor’, a rose variety from the same inventors described and illustrated in U.S. Plant patent application Ser. No. 10/339,871 dated Jan. 10, 2003 are compared to ‘POULpm001’ in Chart 1.
