USPP17359P2 - Miniature rose plant named ‘Poulpah035’ - Google Patents

Abstract

A new miniature rose plant that has abundant, dark red 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: ‘Poulpah035’.

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, an unnamed seedling, and the male pollen parent an-unnamed seedling.

The two parents were crossed during the summer of 2002 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety, named ‘Poulpah035’, 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 is less compact in growth habit than ‘Poulpah035’.

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

• • 1. Flowers of the pollen parent have more than 50 flower petals, while flowers of ‘Poulpah035’ have 40 to 50 flower petals.
  • 2. Flowers of ‘Poulpah035’ are red, while flowers of the pollen parent are red to red-purple.

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 dark red flowers which retain their color as flowers mature;
  • 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 ‘Poulpah035’ 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. ‘Poulpah035’ was selected by the inventor as a single plant from the progeny of the hybridization in April 2003.

Asexual reproduction of ‘Poulpah035’ by cuttings and traditional budding was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in 2003. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpah035’ are true to type and are transmitted from one generation to the next.
