Rose plant Jactred

Abstract

A hybrid tea rose variety having continuous production of large red flowers, upright and vigorously growing bush, 7 leaflet leaves and bright yellow anthers with red centers.

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 American Pride, U.S. Plant Pat. No. 4,139.

The primary objective of this breeding was to produce a new rose variety of the hybrid tea class with large red blossoms, excellent vigor and full season flower production. 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. Large (5") bright red flowers;

2. Vigorous upright growing bush;

3. Heavy and continuous flower production;

4. Frequent 7 leaflet leaves;

5. A slight flower fragrance; and

6. Anthers of bright yellow with reddish centers.

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:
