Abstract
A new and distinct variety of rose with long lasting, novel dark red flowers, and attractive foliage with good disease resistance. It exhibits 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 ‘KORpot028’.
There are no cross referenced or related applications. This variety was developed without the aid of any research grant.
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 2009. The crossing was between an ‘un-named seedling’, the seed parent, and another ‘un-named seedling’, the pollen parent by the same inventor.
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 ‘KORpot028’.
The new rose plant may be distinguished from its seed parent, an ‘un-named seedling’, by the following combination of characteristics:
-
- 1. ‘KORpot028’ has a very good shelf life, whereas the ‘un-named seedling’ had a good shelf life.
- 2. ‘KORpot028’ has a moderately large sized flower, whereas the ‘un-named seedling’ has a medium sized flower.
The new rose plant may be distinguished from its pollen parent, an ‘un-named seedling’, by the following combination of characteristics:
-
- 1. ‘KORpot028’ has a dark red flower, whereas the ‘un-named seedling’ has an orange-red flower.
- 2. ‘KORpot028’ has a double petal count, whereas the ‘un-named seedling’ has a very double petal count.
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 and foliage;
- 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 known to the inventor. These objectives have been substantially achieved and in that distinguish ‘KORpot028’ from all other varieties of which I am 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 ‘KORpot028’ was selected in April 2010 from the seedling beds to be asexually propagated for further evaluation. The first asexual propagation of ‘KORpot028’ was done by rooting softwood cuttings in June 2010 at the inventor's nursery in Offenseth-Sparrieshoop, Germany.
These initial and other subsequent propagations conducted in controlled environments demonstrate that ‘KORpot028’ reproduces true to type in successive generations of asexual reproduction.
The accompanying color drawing shows as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, sepals, reproductive organs, a flower, leaves, prickles, and stems of ‘KORpot028’.
The following is a description of ‘KORpot028’, as observed growing in April 2013 in a nursery in Jackson County, Oreg. on plants of 12 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 ‘KORpot003’, a rose variety from the same inventor described and illustrated in U.S. Plant Pat. No. 23,795 and filed on Feb. 14, 2012 are compared to ‘KORpot028’ in Chart 1.
