Rose plant Jachad

Abstract

A hybrid tea rose variety having upright, vigorous growth, dark green foliage, orange and yellow blend flowers, powdery mildew resistance, profusion of small prickles on stems and large, sweet-tasting orange-colored hips.

Description

This present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by crossing an unnamed variety with the variety Sunshine, U.S. Plant Pat. No. 3,791.

The primary objective of this breeding was to produce a new rose variety of the hybrid tea class exhibiting a rich blend of yellow and orange combined with good growth habits. This 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. An unusual blend of yellow and orange color;

2. Upright vigorous growth;

3. Powdery mildew resistance;

4. Stems covered with small prickles;

5. Dark green foliage; and

6. Large orange-colored hips.

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 in terminology in accordance with The Royal Horticultural Society Colour Chart except where ordinary dictionary significance of color is indicated:
