USPP15383P2 - Rose plant named ‘POULpm002’ - Google Patents

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: ‘POULpm002’.

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 female seed parent, an unnamed seedling, and the male pollen parent ‘Macrexy’, described and illustrated in U.S. Plant Pat. No. 6,713 dated Apr. 4, 1989. The two parents were crossed during the summer of 1989 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULpm002’.

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

1. The seed parent has near white flower petals, while ‘POULpm002’ has pink flower petals.

2. The seed parent has a taller growth habit than ‘Poulpm002’.

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

1. Flowers of ‘MACrexy’ have 39 to 51 petals while flowers of ‘Poulpm002’ have 26 to 30 petals.

2. While the outer surface of flower petals of ‘MAXrexy’ are Red 55A to Red 56D in color, the outer surface of petals for ‘Poulpm002’ is Red-Purple Group 63C.

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. Dense, uniform growth 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 ‘POULpm002’ 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 1989 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULpm002’ was selected in the spring 1990 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULpm002’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in July, 1990. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULpm002’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULpm002’, 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 ‘TANalapin’, described and illustrated in U.S. Plant Pat. No. 14,091 issued Aug. 26, 2003 are compared to ‘POULpm002’ in Chart 1.
