Abstract
A new and distinct variety of miniature rose with long lasting, novel red flowers, and abundant dark green and attractive foliage. It exhibits compact, uniform growth and flowering under greenhouse conditions when grown as a potted floral plant. 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
Genus, species and Variety denomination: The botanical classification of the new rose plant is Rosa hybrida, ‘KORpolare’.
The new variety of miniature rose plant of the present invention originated from a controlled crossing in a breeding program between ‘KORkleiva’, a patented rose described and illustrated in U.S. Plant Pat. No. 11,232 issued on Feb. 22, 2000, and ‘Poulrac’ a patented rose described and illustrated in U.S. Plant Pat. No. 11,543 issued on Oct. 3, 2000.
The two parents were crossed and the resulting seeds were planted in a controlled greenhouse environment. The resulting seedlings exhibited distinctive physical and biological characteristics. The new rose plant was selected in as a single plant from the seedling beds due to its superior characteristics and asexually propagated for further evaluation. This new and distinctive miniature rose variety is named ‘KORpolare’.
The new rose plant may be distinguished from its seed parent, ‘KORkleiva’, by the following combination of characteristics:
-
- 1. ‘KORpolare’ has dark red flowers while ‘KORkleiva’ has cream white flowers,
- 2. ‘KORpolare’ has an average of 55 petals, white ‘KORkleiva’ has 25 to 30 petals.
The new rose plant may be distinguished from its pollen parent, ‘Poulrac’ by the following combination of characteristics:
-
- 1. ‘Poulrac’ has small flowers with few petals and ‘KORpolare’ has medium to large sized flowers with numerous (very double) petals.
- 2. ‘Poulrac’ has medium sized leaves of average abundance while ‘KORpolare’ has larger leaves with above average abundance.
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 under greenhouse conditions when grown as a potted floral plant;
- 2. Abundant, long lasting, and attractive flowers on upright stems;
- 3. Resistance to diseases encountered in greenhouse and nursery culture; and
- 4. Suitability for production from softwood cuttings in floral and nursery containers;
This combination of qualities is not present in prior rose cultivars. These objectives have been substantially achieved and in that distinguish ‘KORpolare’ from all other varieties of which we are aware.
As part of the rose development program, Tim-Hermann Kordes germinated the 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 ‘KORpolare’ was selected in May, 2000 from the seedling beds to be asexually propagated for further evaluation. The first asexual reproduction of ‘KORpolare’ was done by rooting softwood cuttings in July, 2000 at the Rosa-Danica Nursery in Odense, Denmark.
This initial and other subsequent propagations conducted in controlled environments show that the foregoing and all other characteristics of ‘KORpolare’ come true to form and are transmitted through succeeding generations.
The accompanying color illustration shows as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of flower buds, flowers, sepals, several stems and a leaf of ‘KORpolare’.
The following is a description of ‘KORpolare’, as observed in its growth in April, 2006 in a nursery in Jackson County, Oreg. on plants of 6 months 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 ‘Poulhappy’, a patented rose variety described and illustrated in U.S. Plant Pat. No. 9,483 and issued on Mar. 26, 1996 are compared to ‘KORpolare’ in Chart 1.
