Miniature rose variety ‘POULhi005’

Abstract

A new miniature rose which has abundant, 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

SUMMARY OF THE INVENTION

Botanical classification: Rosa hybrida.

Variety denomination: ‘POULhi005’.

Commercial classification: Miniature Rose Plant.

The present invention constitutes a new and distinct variety of miniature rose plant which originated from a controlled crossing between ‘POULsabel’, described and illustrated in U.S. Plant patent application Ser. No. 09/607,333 dated Jun. 30, 2000 and an unnamed, not patented seedling. The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘POULhi005’.

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

1. The general tonality of ‘POULsabel’ is Red Group 53A, while that of ‘POULhi005’ is Red Group 45B.

2. The blooms of ‘POULsabel’ are borne singly, while those of ‘POULhi005’ are borne 5 to 7 per flowering stem.

3. The shape of ‘POULsabel’'s petals is deltoid, while those of ‘POULhi005’ are obovate.

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

1. The general tonality of the unnamed pollen parent is darker than that of ‘POULhi005’.

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 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 and distinguish ‘POULhi005’ 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 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULhi005’ was selected by the inventors as a single plant from the progeny of the hybridization in May of 1999. Asexual reproduction of ‘POULhi005’ by cuttings and traditional budding was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in October 1999. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULhi005’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULhi005’, as observed in its growth in a field nursery in Jackson County, Oreg. The observed plants are 3 years of age. 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 ‘POULhappy’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 9,483 and issued on Mar. 26, 1996 are compared to ‘POULhi005’ in Chart 1.
