Abstract

A rose plant of the hybrid tea class, characterized by the unique combination of its novel flower color; its dark green, glossy, powdery mildew resistant foliage; its long, strong stems; its excellent petal substance, and its heavily appendaged sepals.

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 the variety MERko, U.S. Plant Pat. No. 3,724, with the variety JACblem, U.S. Plant Pat. No. 4,847.
The primary objective of this breeding was to produce a new rose variety having the excellent petal substance, long vase life, and good cut-flower production of MERko combined with the longer stems, dark, glossy foliage, and powdery mildew resistance of JACblem. It was hoped flower color would fall between orange and yellow, the colors of the two parents. This 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. Excellent petal substance;
2. Long, strong stems;
3. Good mildew resistance;
4. Novel flower color;
5. Glossy, dark green foliage; and
6. Heavily bearded sepals.
Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristics and all other features 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 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.
