Abstract

A new and distinct variety of Hybrid Tea rose plant which have attractive magenta-purple colored flowers and attractive dark green and glossy foliage. The buds are large and well turbinated. This new variety is having high production of long stems with a long vase life, vigorous, upright growth, and good tolerance to powdery mildew. The variety successfully propagates from softwood cuttings and is well suitable for year round production of cut flowers in commercial glass houses as a flowering cut rose. This and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Description

Latin name of genus and species: Rosa hybrid ‘KORjafir’.
Variety denomination: The new variety is named ‘KORjafir’.
BACKGROUND OF THE INVENTION
The present invention constitutes a new and distinct variety of Hybrid Tea rose plant, which was developed by artificially pollinating an unnamed seedling(not patent in the United States) with an unnamed seedling (not patent in the United States). The two parents were crossed in the summer of 1999 and the resulting seed was sown in December 1999, in a controlled glasshouse environment. Out of these seedlings one seedling was selected, as the new variety and named ‘KORjafir’. The new rose may be distinguished from its seed parent, an unnamed seedling, by the following combination of characteristics:
1. The unnamed seedlings has a breeding background in unnamed seedlings.
2. ‘KORjafir’ has big double flowers, while the unnamed seedling has medium-doubled flowers.
3. ‘KORjafir’ has dark pink colored petals, while the unnamed seedling has dark red petals.
The new variety may distinguished from its pollen parent, an unnamed seedling created by the same inventor, by the following combination of characteristics:
1. The unnamed seedling has a breeding background in unnamed seedlings.
2. ‘KORjafir’ has bigger flowers and foliage as compared to the unnamed seedling.
3. ‘KORjafir’ has dark pink colored petals, while the unnamed seedling has light pink petals.
BRIEF SUMMARY OF THE INVENTION
Initial asexual reproduction of ‘KORjafir’ by cuttings was first done in Klein Offenseth-Sparrieshoop, Germany. The reproduction was conducted in controlled greenhouse environments. Have here proven to be stabile by propagation with cuttings in several generations.
‘KORjafir’ is a high productive Hybrid Tea rose with a vaselife of approximately 14 days. ‘KORjafir’ under conventional greenhouse production ( 18 degree Celcius nights, and 26 Celcius day's) in Germany will produce 170-240 stems per year, averaging 70 cm long.
The objective of the hybridization of this rose variety for commercial greenhouse culture was to create a new and distinct variety with:
1. Uniform and abundant flowers with good vaselife.
2. Attractive long lasting foliage and strong growth.
3. Year round flowering under glasshouse conditions.
4. Suitability for production from softwood cuttings.
5. Durable flowers and foliage which make the variety suitable for distribution in the floral industry.
This combination of qualities was not present in previously available commercial cultivars of this type and distinguish ‘KORjafir’ from all other varieties of which we are aware.
The seeds from hybridization were planted in a controlled environment and evaluations were conducted on the resulting plants. ‘KORjafir’ was selected by Wilhelm Kordes in his development program in Klein Offenseth-Sparrieshoop, Germany.

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY
The following is a detailed description of the Hybrid Tea Rose: Rosa hybrid ‘KORjafir’.
The following observations, measurements, values and comparisons describe plants grown in glass houses in Klein Offenseth-Sparrieshoop, Germany. The age of the observed plants where 11 to 13 months after propagation by cuttings, and produced as flowering cut-rose plants.
Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 1995, except where common terms of color are used. For a comparison, the nearest existing rose variety is ‘Magic Beauty’, a rose variety described and illustrated in U.S. Plant Pat. No. 12,655.
Chart 1 details several physical characteristics of ‘Korjafir’ and ‘Magic Beauty’.
