Floribunda rose plant named `Poulrek`

Abstract

A repeat flowering floribunda having a very even compact growth habit, glossy dark green foilage, rapid repeat flowering with new shoots forced behind the terminal flower to produce constant bloom, resistance to rose powdery mildew and rust, and readily propagated by budding or soft wood cuttings.

Description

The present invention relates to a new and distinct variety of rose plant of the floribunda class which was originated by out crossing the variety MACrexy, U.S. Plant Pat. No. 6713, with an unnamed seedling.

The primary objective of this breeding was to produce a new rose variety having the compact free flowering characteristic of the female parent combined with the compact plant habit, even growth, rapid repeat bloom and resistance against fungal diseases of the male parent. 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 we are aware:

1. A very even compact growth habit;

2. Glossy dark green foliage;

3. Rapid repeat flowering with new shoots forced behind the terminal flower to ensure constant bloom;

4. Ease of propagation by budding or soft wood cuttings; and

5. Resistance to rose powdery mildew and rust.

Asexual reproduction of this new variety by budding and by softwood cuttings, as performed at Wasco, Calif. and Fredensborg, Denmark, shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

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.

The following is a detailed description of our new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.

The major color on the upper side is Red Group 36D.

Claims

1. A new and distinct variety of rose plant of the floribunda class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its very even compact growth; its rapid repeat bloom; its resistance to powdery mildew and rust; its dark green glossy foliage; and its ease of propagation by budding and by softwood cuttings.
