Miniature rose plant named ‘KORpagbel’

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.

Description

Genus, species and variety denomination: The botanical classification of the new rose plant is Rosa hybrida, var. ‘KORpagbel’.

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 ‘KORnisecco’, a non-patented rose and ‘KORanalafi’ a non-patented rose.

The two parents were crossed and the resulting seeds were planted in a controlled greenhouse environment. The resulting seedlings 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 for further evaluation. This new and distinctive miniature rose variety is named ‘KORpagbel’.

SUMMARY OF THE INVENTION

The new rose plant may be distinguished from its seed parent, KORnisecco by the following combination of characteristics:

• • 1. KORpagbel has light salmon-pink flowers while KORnisecco has cream colored flowers,
  • 2. KORpagbel has very double flowers while KORnisecco has only double flowers; and
  • 3. KORpagbel as a shelf life of 21 days while KORnisecco has a shelf life of only 14 days.

The new rose plant may be distinguished from its pollen parent, KORanalafi by the following combination of characteristics:

• • 1. KORpagbel has light salmon-pink flowers while KORanalafi has salmon-orange flowers,
  • 2. The flowers of KORpagbel have a diameter of 40-50 mm while the flowers of KORanalafi have diameters of 30 mm,
  • 3. KORpagbel has a better branching while KORanalafi has fewer branches.

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 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 ‘KORpagbel’ 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 ‘KORpagbel’ was selected in May, 2001 from the seedling beds and asexually propagated for further evaluation. The first asexual reproduction of ‘KORpagbel’ by softwood cuttings was in July, 2001 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 ‘KORpagbel’ come true to form and are transmitted through succeeding generations.

DETAILED BOTANICAL DESCRIPTION

The following is a description of>KORpagbel, as observed in its growth in October, 2003 in a nursery in Jackson County, Oreg. on plants of 1 year 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 ‘KORstrunek’, a non-patented rose variety from the same inventor compared to ‘KORpagbel’ in Chart 1.
