USPP10650P - Hybrid Tea rose plant named `TANkalcig` - Google Patents

Abstract

Hybrid Tea rose having bright red flowers of good petal count on long, straight stems, with moderate thorns, the plant having glossy, dark green foliage and good cut flower production.

Description

The present invention relates to a new and distinct variety of rose plant of the Hybrid Tea class which was originated by me by crossing `TANorelav` (unpatented), with the variety `KORlimit` (unpatented).

The primary objective of this breeding was to produce a new rose variety having the dark, glossy foliage; good cut flower production; and high petal count of the female, combined with the very long stems, low number of thorns, and bright red color 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 I am aware:

1. Long, straight stems;

2. Clear, bright red flowers;

3. Glossy, dark green foliage;

4. Production of 24-26 stems per plant, per year under California greenhouse condtions;

5. Good petal count for a cut rose (30);

6. Moderate thorn production.

`TANkalcig` is a cut flower, greenhouse produced rose. Production is 24 -26 stems per plant per year with long stems, glossy, powdery mildew resistant foliage and very dark, but bright red flowers.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagation.

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 my new rose cultivar with color descriptions using terminology in accordance with The Royal Horitcultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.
