Groundcover Rose Plant Named ‘TAN04999’

Abstract

Groundcover rose plant having resistance to black spot, resistance to powdery mildew and prolific pink-red blooms.

Description

Genus and species: Rosa L.

Varietal denomination: ‘TAN04999’.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of ground cover rose plant named ‘TAN04999’, which was originated by me by crossing ‘TANotax’ (PP11,572, seed parent) with ‘Royal Bassino’ (unpatented, pollen parent).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new groundcover rose variety that is resistant to black spot and powdery mildew.

BRIEF SUMMARY OF THE INVENTION

The objective was substantially achieved, along with other desirable improvements, as evidenced by the unique combination of characteristics described hereinafter 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. Resistance to black spot.
  • 2. Resistance to powdery mildew.
  • 3. Prolific pink-red blooms.

Asexual reproduction of this new variety by grafting on Rosa canina rootstock at the facilities of Rosen Tantau, Uetersen, Germany, 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

‘TAN04999’ has flowers that are darker in color than the flowers of the seed parent and the plant height is taller (60-70 cm for ‘TAN04999’) than its pollen parent (50-60 cm for ‘Royal Bassino’).

COMPARISON WITH SIMILAR VARIETY

The variety that is most similar to ‘TAN04999’ is believed to be ‘TANotax’; as compared above.

BRIEF DESCRIPTION OF THE ILLUSTRATIONS

The accompanying illustrations show typical specimens of the flowers of this new variety depicted in color as nearly true as it is reasonably possible to make the same in color illustrations of this character.
