Abstract
A new and distinct variety of miniature rose with long lasting, novel yellow flowers, and 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
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 ‘KORfrosdra’.
The new variety of miniature rose plant of the present invention originated from a controlled crossing in a breeding program between an ‘un-named seedling’ and ‘KORmutric’.
The hybridization, seed production, seed germination, seedling selection, and subsequent propagations were conducted in controlled greenhouse environments. 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 miniature rose variety is named ‘KORfrosdra’.
The new rose plant may be distinguished from its seed parent, an ‘un-named seedling’, by the following combination of characteristics:
-
- 1. The flower size of the ‘un-named seedling’ is large while the flower size of ‘KORfrosdra’ is medium, and
- 2. The flower color of the ‘un-named seedling’ is light yellow while the flower color of ‘KORfrosdra’ is yellow.
The new rose plant may be distinguished from its pollen parent, ‘KORmutric’ by the following combination of characteristics:
-
- 1. The flower size of ‘KORmutric’ is small while the flower size of ‘KORfrosdra’ is medium, and
- 2. The flower color of the ‘KORmutric’ is copper yellow while the flower color of ‘KORfrosdra’ is yellow.
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 ‘KORfrosdra’ 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 ‘KORfrosdra’ was selected in May, 2004 from the seedling beds to be asexually propagated for further evaluation. The first asexual reproduction of ‘KORfrosdra’ was done by rooting softwood cuttings in July, 2004 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 ‘KORfrosdra’ 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 the buds, flowers, leaves, and stems of ‘KORfrosdra’. Specifically illustrated is: a flower bud, partially opened bloom, open bloom, floral parts, sepals, juvenile foliage, a stem exhibiting thorns, and leaves.
The following is a description of ‘KORfrosdra’, as observed in its growth in April, 2008 in a greenhouse in Jackson County, Oregon on plants of 4 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 ‘KORspunty’, a rose variety from the same inventor described and illustrated in U.S. Plant Pat. No. 17,402 and issued on Feb. 6, 2007 are compared to ‘KORfrosdra’ in Chart 1. ART 1
