Miniature rose plant named ‘Poulpah038’

Abstract

A new miniature rose plant that has abundant, red striped flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year-round production in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Description

Botanical designation: Rosa hybrid.

Variety denomination: ‘Poulpah038’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of miniature rose plant which originated from a controlled crossing between the female seed parent, ‘Poulgrad’ U.S. Plant Pat. No. 11,610, and the male pollen parent an unnamed seedling.

The two parents were crossed during the summer of 1998 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety, named ‘Poulpah038’, originated as a single seedling from the stated cross.

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

• • 1. The seed parent has a petal count of 25 to 30 petals. ‘Poupah038’ has 17 to 18 petals, 1 to 2 of which are petaloids.
  • 2. Flowers of the seed parent have a general tonality of Red Group 53A to Red Group 46A. Flowers of ‘Poulpah038’ are Red Group 42A to 43A with streaks of Red Group 38B to 38C.

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

• • 1. The pollen parent has flowers which are 35 to 40 mm in diameter. Flowers of ‘Poulpah038’ are normally 45 mm in diameter.
  • 2. Flowers of the pollen parent are generally colored Red with white and yellow color streaks. Flowers of ‘Poulpah038’ are Red Group 42A to 43A with streaks of Red Group 38B to 38C.

The objective of the hybridization of this rose variety for commercial culture was to create a new and distinct variety with unique qualities, such as:

• • 1. Uniform and abundant red striped flowers;
  • 2. Vigorous and compact growth;
  • 3. Durable flowers and foliage which make a variety suitable for distribution in the floral industry;
  • 4. Excellent disease resistance.

This combination of qualities is not present is previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulpah038’ 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 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark. ‘Poulpah038’ was selected by the inventor as a single plant from the progeny of the hybridization in 1998.

Asexual reproduction of ‘Poulpah038’ by cuttings and traditional budding was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in 1999. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpah038’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpah038’, as observed in its growth in Jackson County, Oreg. Observed plants are 2 years of age and were cultivated in an open field grown on Rosa multiflora understock. Color references are made using the Royal Horticultural Society (London, England) Colour Chart, 2003, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘Poulcub’, described in U.S. Plant patent application Ser. No. 10/647,010 dated Aug. 21, 2003, now abandoned, are compared to ‘Poulpah038’ in Chart 1.
