Miniature rose plant named ‘Poulpar033’

Abstract

A new miniature rose plant that has abundant, pink and white 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 classification: Rosa hybrid.

Variety denomination: ‘Poulpar033’.

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 parent ‘KORstoffein’ described and illustrated in U.S. Plant Pat. No. 11,242 issued February 22, 2000, and the male pollen parent plant, an unnamed seedling. The two parents were crossed, and the resulting seeds were planted in a controlled environment. The new variety is named ‘Poulpar033’.

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

• • 1. ‘Poulpar033’ has a flower color of Red-Purple Group 67B as sepals unfold while ‘KORstoffein’ has a flower color of Red Group 52D with the veins, especially the mid rib, being Orange-White group 159D as sepals unfold.
  • 2. ‘Poulpar033’ has a receptacle color of Yellow-Green Group 144A to 144B while ‘KORstoffein’ has a receptacle color of Yellow-Green Group 146C.
  • 3. ‘Poulpar033’ has a petal count of 40 to 45 petals while ‘KORstoffein’ exhibits 25 to 30 petals.

The new variety may be distinguished from its pollen parent, created by the same inventors, by the following combination of characteristics:

• • 1. The pollen parent achieves an overall height of 40 cm, while ‘Poulpar033’ is normally 20 to 30 cm in height.
  • 2. ‘Poulpar033’ has small flowers between 45-55 mm while the unnamed pollen parent has larger flowers between 10 and 15 cm.

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 pink and white striped flowers;
  • 2. Vigorous and compact growth;
  • 3. Year-round flowering under glasshouse conditions;
  • 4. Suitability for production from softwood cuttings in pots;
  • 5. Durable flowers and foliage which make a variety suitable for distribution in the floral industry.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulpar033’ 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.

‘Poulpar033’ was selected by the inventor as a single plant from the progeny of the hybridization in June 2002.

Asexual reproduction of ‘Poulpar033’ by cuttings and traditional budding was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in April 2002. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpar033’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpar033’, as observed in its growth in glasshouses in Odense, Denmark. Observed plants are 4 months of age, and were cultivated in 10.5 cm pots. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘Poulra021’, a rose variety from the same inventor, described and illustrated in U.S. Plant Pat. No. 15,506 on Feb. 1, 2005, are compared to ‘Poulpar033’ in Chart 1.
