Hybrid tea rose plant named `JACchry`

Abstract

Hybrid tea rose plant having distinctive large, well shaped flowers, strong stable deep pink flower color, vigorous upright growth habit, dark green glossy foliage and sweet smelling fragrance.

Description

The present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by the inventor by crossing an unnamed seedling with the variety Chrysler Imperial, U.S. Plant Pat. No. 1,167.

The primary objective of this breeding was to produce a new rose variety having the large glossy foliage of the female white flowered parent combined with the very large flower size and fragrance of the male parent. 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. Very large well shaped hybrid tea buds and flowers;

2. Vigorous, upright habit of growth;

3. Glossy, dark green foliage;

4. Pleasant, sweet fragrance;

5. Strong, stable, deep pink flower color.

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 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.
