Hybrid tea rose plant named `Jacheir`

Abstract

A hybrid tea rose plant having deep red-purple flowers of good hybrid tea form, strong fragrance, glossy green foliage and excellent plant vigor.

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 an unnamed seedling with the variety "Heirloom" (U.S. Plant Pat. No. 3,234).

The primary objective of this breeding was to produce a new rose variety having the good bud form, vigor and disease resistance of the female unnamed, lavender pink, hybrid tea seedling combined with the deep lavender purple flower color and fragrance of the hybrid tea male parent "Heirloom." 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. Deep red-purple flowers of good form;

2. Strong fragrance;

3. Glossy green foliage; and

4. Excellent vigor.

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 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.
