Miniature rose plant named ‘Poulpar030’

Abstract

A new miniature rose plant that has abundant, apricot 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: ‘Poulpar030’.

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, ‘KORkleiva’ described and illustrated in U.S. Plant Pat. No. 11,232, issued Feb. 22, 2000, and the male pollen parent, an unnamed seedling. The two parents were crossed, and the resulting seeds were planted in a controlled environment. The new variety is named ‘Poulpar030’.

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

• • 1. Petal count of ‘Poulpar030’ is 25 petals. The seed parent has 25 to 30 petals.
  • 2. ‘Poulpar030’ has apricot flowers, whereas the seed parent has light yellow flowers.

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

• • 1. Petal count of ‘Poulpar030’ is 25 petals. The pollen parent has 50 petals.
  • 2. ‘Poulpar030’ has apricot flowers, while the pollen parent has orange flowers.

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 apricot 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 inventors, and distinguish ‘Poulpar030’ 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.

‘Poulpar030’ was selected by the inventor as a single plant from the progeny of the hybridization in 2001.

Asexual reproduction of ‘Poulpar030’ 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 ‘Poulpar030’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpar030’, as observed in its growth in glasshouses in Burlington, Canada. 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 ‘Poulnil’, a rose variety from the same inventor described and illustrated in U.S. Plant Pat. No. 13,301 and issued on Dec. 3, 2002, are compared to ‘Poulpar030’ in Chart 1.
