Abstract
A new and distinct variety of rose with long lasting, novel yellow flowers with red edges, and attractive foliage with good disease resistance. It exhibits uniform 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 ‘KORgohowa’.
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 spring of 2001. The crossing was between an unnamed seedling, and another unnamed 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 ‘KORgohowa’.
The new rose plant may be distinguished from its seed parent, an unnamed seedling, by the following combination of characteristics:
-
- 1. Foliage on ‘KORgohowa’ is moderately glossy, while foliage on the unnamed seedling is very glossy.
- 2. ‘KORgohowa’ has on average 50-60 petals, while the unnamed seedling has, on average, 10-15 petals.
The new rose plant may be distinguished from its pollen parent, an unnamed seedling by the following combination of characteristics:
-
- 1. Flower diameter of ‘KORgohowa’ is 70 mm on average, while flower diameter of the unnamed seedling is 120 mm on average.
- 2. ‘KORgohowa’ has on average 50-60 petals, while the unnamed seedling has on average 30-40 petals.
The objective of the hybridization was to create a new and distinct rose plant with unique qualities, such as:
-
- 1. Uniform growth and flowering;
- 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 ‘KORgohowa’ 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 ‘KORgohowa’ was selected in May, 2002 from the seedling beds to be asexually propagated for further evaluation. The first asexual propagation of ‘KORgohowa’ was done by budding to seedling understocks in July, 2002 at the inventor's nursery in Offenseth-Sparrieshoop, Germany.
This initial and other subsequent propagations conducted in controlled environments demonstrate that ‘KORgohowa’ 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, flowers, leaves, and stems of ‘KORgohowa’.
The following is a description of ‘KORgohowa’, as observed growing in September, 2010 in a nursery in Jackson County, Oreg. on plants of 4 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 ‘KORresia’, a rose variety from the same inventor described and illustrated in U.S. Plant Pat. No. 3,509 and issued on Mar. 5, 1974 are compared to ‘KORgohowa’ in Chart 1.
