Climber rose plant named ‘ADABARING’

Abstract

Climber rose plant having vigor; more numerous leaves than the ‘DELSIRE’ cultivar; dark red color; better climbing-up capability than the ‘DELSIRE’ cultivar; disease resistance; and strong fragrance.

Description

Genus and species: Rosa hybrida.

Variety denomination: ‘ADABARING’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a climber rose plant named ‘ADABARING’ which was originated by me by crossing the variety ‘DELSIRE’ (unpatented), with the variety ‘MEITULIMON’ (unpatented).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety having a large double red climbing rose, strong foliage with more vigor and energy, a better climbing-up activity and a dark red color.

BRIEF SUMMARY OF THE INVENTION

The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

• • 1. More vigor in comparison to the ‘DELSIRE’ cultivar.
  • 2. More leaves in comparison to the ‘DELSIRE’ cultivar.
  • 3. Dark red flowers.
  • 4. Better climbing-up capability in comparison to the ‘DELSIRE’ cultivar.
  • 5. Disease resistance to black spot and Sphaeroteca pannosa.
  • 6. Extremely fragrant in comparison to the ‘DELSIRE’ cultivar.

Asexual reproduction of this new variety by grafting onto Rosa multiflora (unpatented) rootstock, as performed at Liffre, France, shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

Comparison with Parents

The female parent ‘DELSIRE’ is less fragrant, has bigger leaves, is less vigorous, and in comparison to ‘ADABARING’. ‘DELSIRE’ has deep crimson red flowers. The male parent ‘MEITULIMON’ is less vigorous and has mauve-pink flowers in comparison to ‘ADABARING’.

Comparison with Similar Variety

With reference to the above comparison with the parent plants, ‘DELSIRE’ is believed to be the most similar cultivar to the new ‘ADABARING’ plant.

BRIEF DESCRIPTION OF THE ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart (2001), except where ordinary dictionary significance of color is indicated. It should be noted that color is difficult to determine precisely and can vary with growing conditions.
