Abstract

A new and distinct variety of rose with abundant, novel pink flowers, and attractive foliage with very good disease resistance. It exhibits vigorous growth and an upright climbing habit. The new variety propagates well from traditional methods. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

CROSS REFERENCES AND FEDERAL R&D STATEMENT

There are no cross referenced or related applications. This variety was developed without the aid of any research grant.

Latin name of genus and species: The botanical classification of the new rose plant is Rosa hybrida.

Variety denomination: The denomination of the new variety is ‘KORadigel’.

BACKGROUND OF THE INVENTION

The new variety of rose plant of the present invention originated from a controlled crossing in a breeding program of two distinct parents during the summer of 1994. The crossing was between an un-named seedling and an un-named seedling.

The resulting seeds were planted during the following winter. The resulting seedlings were evaluated and exhibited distinctive physical and biological characteristics. The new rose plant was selected as a single plant from the seedling beds due to its superior characteristics and asexually propagated for further evaluation. This new and distinctive rose variety is named ‘KORadigel’.

SUMMARY OF THE INVENTION

The new rose plant may be distinguished from its seed parent, an un-named seedling whose parents were La Sevillana and Sympathie, by the following combination of characteristics:

- 1. ‘KORadigel’ has pink flowers while the seed parent has red flowers, and
- 2. the flowers of ‘KORadigel’ have more petals and stronger fragrance.

The new rose plant may be distinguished from its pollen parent, an un-named seedling by the following combination of characteristics:

- 1. ‘KORadigel’ has pink flowers while the pollen parent has yellow flowers, and
- 2. the flowers of ‘KORadigel’ have more petals and stronger fragrance.

The objective of the hybridization was to create a new and distinct rose plant with unique qualities, such as:

- 1. Vigorous, upright growth with long arching canes;
- 2. Abundant attractive, recurrent flowers;
- 3. Attractive and abundant foliage, and;
- 4. Resistance to diseases encountered in landscapes and gardens.

This combination of qualities is not present in prior rose varieties. These objectives have been substantially achieved and in that distinguish ‘KORadigel’ from all other varieties of which we are aware.

As part of a rose development program, Tim-Hermann Kordes germinated seeds from the aforementioned hybridization and conducted evaluations and observations on the resulting seedlings in a controlled environment in Offenseth-Sparrieshoop, Germany. The resulting seedlings exhibited distinctive physical and biological characteristics. The new rose plant ‘KORadigel’ was selected in May, 1995 from the seedling beds to be asexually propagated for further evaluation. The first asexual propagation of ‘KORadigel’ was done by budding to seedling understocks in July, 1995 at the W. Kordes Söhne Nursery in Offenseth-Sparrieshoop, Germany.

This initial and other subsequent propagations conducted in controlled environments show that the foregoing and all other characteristics of ‘KORadigel’ come true to form and are transmitted through succeeding generations.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color illustration, labeled as SHEET 1, shows as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of open flowers of ‘KORadigel’.

DETAILED BOTANICAL DESCRIPTION
