Miniature rose plant named `JACquest`

Abstract

A miniature rose plant having bright red, 11/2" flowers borne singly and in small cluster; high petal substance; upright pot rose habit; and long flower life.

Description

The present invention relates to a new and distinct variety of rose plant of the miniature class which was originated by me by crossing an unnamed seedling (whose parents are unnamed seedling×`RUImired` U.S. Plant Pat. No. 5,770), with the variety `POULvic`, U.S. Plant Pat. No. 8,012.

The primary objective of this breeding was to produce a new pot rose variety having red flowers with high petal substance (texture), flowers borne in small clusters, an upright plant habit suitable for potted plant production from softwood cuttings, grown in a greenhouse in 4-inch pots and possessing long flower life. 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. Bright red, 11/2 inch flowers, borne singly and in small clusters;

2. High petal substance;

3. Upright, pot rose habit; and

4. Long flower life (16 days).

The plant gives 18-21 days of shelf life, making it very suitable for use as a pot rose.

Asexual reproduction of this new variety by cuttings, as performed at Somis, 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.
