Abstract

Hybrid Tea rose adapted to greenhouse production on long stems of salmon pink flowers having long vase life, the foliage being dark green, glossy, and disease resistant.

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 two unnamed seedlings.

The primary objective of this breeding was to produce a new rose variety having long stems, pink blooms, high production and good vase life. The objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Large, clear salmon pink flowers;

2. Long, straight stems;

3. Good cut rose production (175-200 stems per m² of greenhouse);

4. Excellent vase life;

5. Dark green, glossy, disease-resistant foliage.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., 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 my 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.

Parentage:

Claims

I claim:

1. A new and distinct variety of rose plant of the Hybrid Tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its long, straight stems; its good production of cut flowers per m² of greenhouse; its excellent vase life; its large, clear salmon pink flowers, and its dark green, glossy, disease-resistant foliage.
