Abstract

A new and distinct variety of rose with long lasting, novel cream white flowers, with pale peach coloration in the center of the bloom, and attractive foliage with excellent disease resistance. It exhibits uniform, upright to bushy growth with abundant flowers. The new variety propagates well from cuttings and by grafting. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Description

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 ‘KORpriggos’.
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.
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 1997. 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 ‘KORpriggos’.
SUMMARY OF THE INVENTION
The new rose plant may be distinguished from its seed parent, an un-named seedling by the following combination of characteristics:
    • 1. ‘KORpriggos’ has cream white, very double flowers, while the seedling' un-named seedling has semi-double, pink flowers; and
    • 2. ‘KORpriggos’ has an upright to bushy habit while the seedling' un-named seedling has an upright habit.
The new rose plant may be distinguished from its pollen parent, an seedling' un-named seedling by the following combination of characteristics:
1. ‘KORpriggos’ has cream white, very double flowers, while the seedling' un-named seedling has semi-double, pink flowers; and
    • 2. Flowers of ‘KORpriggos’ have a light to moderate floral scent, while the seedling' un-named seedling lacks fragrance.
The objective of the hybridization was to create a new and distinct rose plant with unique qualities, such as:
    • 1. Compact and uniform growth and flowering; when grown as a plant from cuttings;
    • 2. Abundant attractive, recurrent flowers;
    • 3. Attractive and abundant foliage; and
    • 3. Resistance to diseases encountered in landscapes and gardens.
This combination of qualities is not present in prior rose cultivars known to the inventor. These objectives have been substantially achieved and in that distinguish ‘KORpriggos’ 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 ‘KORpriggos’ was selected in May, 1998 from the seedling beds to be asexually propagated for further evaluation. The first asexual propagation of ‘KORpriggos’ was done by budding to seedling understocks in July, 1998 at the inventor's nursery in Offenseth-Sparrieshoop, Germany.
This initial and other subsequent propagations conducted in controlled environments demonstrate that ‘KORpriggos’ reproduces true to type in successive generations of asexual reproduction.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying color illustration shows as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, flowers, leaves, and stems of ‘KORpriggos’.
DETAILED BOTANICAL DESCRIPTION
The following is a description of ‘KORpriggos’, as observed growing in July, 2007 in a nursery in Jackson County, Oreg. on plants of 3 years of age. 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 ‘KORgretaum’, a patented rose variety from the same inventor described and illustrated in U.S. Plant Pat. No. 16,937 and issued on Aug. 1, 2006 are compared to ‘KORpriggos’ in Chart 1.
