ABSTRACT:
Varietal Denomination: ‘KORlobea’
BACKGROUND OF THE NEW PLANT
The present invention constitutes a new and distinct variety of miniature rose plant which was developed by artificially pollinating an unnamed seedling (unpatented) with an unnamed seedling (unpatented).
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 keepability;
2. Attractive long lasting foliage and compact growth;
3. Year round flowering under glasshouse conditions;
4. Suitability for production from softwood cuttings in pots; and
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 ‘KORlobea’ from other varieties.
The two parents were crossed in the summer of 2000 and the resulting seed was sown in December 2000 in a controlled glasshouse environment. The seeds from the hybridization were planted in a controlled environment in Klein Offenseth, Sparrieshoop, Germany and evaluations were conducted on the resulting plants. The instant cultivar originated as a single plant from the stated cross.
Asexual reproduction of ‘KORlobea’ by cuttings was first done in Denmark and later in California in controlled greenhouse environments. The characteristics of the new variety remain true to type through successive propagations.
The new rose variety may be distinguished from its seed parent, an unnamed breeding seedling, by the following combination of characteristics:
1. ‘KORlobea’ has big double flowers, while the seed parent has medium sized single flowers.
2. ‘KORlobea’ has pink colored petals, while the seed parent has light orange-red colored petals.
The new variety may be distinguished from its pollen parent, an unnamed breeding seedling, by the following combination of characteristics:
1. ‘KORlobea’ has bigger flowers and foliage as compared to the pollen parent.
2. ‘KORlobea’ has light pink colored petals, while the pollen parent has dark pink colored petals.
The new variety differs from ‘KORfrauma’, U.S. Plant Pat. No. 11,363, as set forth in Table 1:
