| Abstract: |
A new and distinct variety of miniature rose with long lasting, novel pink 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. |
| Claim: |
I claim:
1. A new and distinct variety of miniature rose plant characterized by the following combination of characteristics: (a) forms abundant, attractive long lasting pink flowers; (b)exhibits a compact and bushy growth habit; (c) is suited for growing in greenhouse in pots from softwood cuttings, and; (d) exhibits durable flowers and foliage suitable for distribution in the floral industry; substantially as herein illustrated anddescribed. |
| 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 `KORbalrom`.
BACKGROUND OF THE INVENTION
The new variety of rose plant of the present invention originated from a controlled crossing during the summer of 2002 in a breeding program between `Poulsabel` (U.S. Plant patent application Ser. No. 10/683,876-now abandoned) and an `un-namedseedling`.
The resulting seeds were planted in a glasshouse during the following winter, subsequently germinated and grew. The resulting seedlings exhibited distinctive physical and biological characteristics. The new rose plant was selected in as asingle plant from the seedling beds due to its superior characteristics and asexually propagated for further evaluation. This new and distinctive rose variety is named `KORbalrom`.
SUMMARY OF THE INVENTION
GENUS, SPECIES AND VARIETY DENOMINATION
The botanical classification of the new rose plant is Rosa hybrida, `KORbalrom`.
BACKGROUND OF THE INVENTION
The new variety of miniature rose plant of the present invention originated from a controlled crossing in a breeding program between the non patented rose variety `Poulsabel` and an `un-named seedling`, which was developed by the same inventor.
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 itssuperior characteristics and asexually propagated for further evaluation. This new and distinctive miniature rose variety is named `KORbalrom`.
SUMMARY OF THE INVENTION
The new rose plant may be distinguished from its seed parent, `Poulsabel`, by the following combination of characteristics: 1. `KORbalrom` has hot pink colored flowers while the seed parent has dark red flowers; and 2. `KORbalrom` is compactand suitable for 10.5 cm pot production while the seed parent is significantly larger and suitable for 15 cm production.
The new rose plant may be distinguished from its pollen parent, an `un-named seedling` by the following combination of characteristics: 1. `KORbalrom` has hot pink colored flowers while the seed parent has medium red flowers; and 2. `KORbalrom`is compact and suitable for 10.5 cm pot production while the pollen parent is significantly larger and suitable for 15 cm production.
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, longlasting, 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 `KORbalrom` 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 `KORbalrom` was selected in May, 2003 from the seedling beds to be asexually propagated for further evaluation. The first asexualreproduction of `KORbalrom` was done by rooting softwood cuttings in July, 2003 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 `KORbalrom` come true to form and are transmitted through succeeding generations.
BRIEFDESCRIPTION OF THE DRAWING
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 `KORbalrom`. Specifically illustrated in SHEET ONEare flower buds, an open bloom, detached petals, detached sepals, stems, and several leaves.
DETAILED BOTANICAL DESCRIPTION
