Rose plant JACapri

Abstract

A new rose variety is disclosed having an unusual yellow-orange flower color; vigorous, upright growth; abundant glands on upper rachises, stipules, axils, and peduncles; very large, long-lasting blooms; and moderate bloom fragrance. Each bloom, borne singly, has about thirty broad petals. The new variety was created by crossing the medium-red variety AROheddo with an unnamed deep yellow seedling.

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 the medium-red unpatented variety AROheddo with an unnamed deep yellow seedling.

The primary objective of this breeding was to produce a new yellow or orange hybrid tea rose variety having the petal count and flower size of AROheddo combined with the broad petals, vigor and glossy foliage of the unnamed seedling. The primary 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. Unusual, distinctive yellow-orange flower color;

2. Vigorous, upright growth;

3. Abundance of glands on upper rachises, stipules and leaf axils, as well as on peduncles;

4. Very large, long-lasting blooms; and

5. Moderate bloom fragrance.

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.

Parentage:

Seed parent.--Variety AROheddo.

The reverse sides of the petals are Orange Group 24D at the petal edges, changing to Orange Group 24C near the center of the petals and finally to Yellow Orange Group 15A near the petal bases. The major color on the upper side is Yellow Orange Group 19C.

Variegation.--None.

Discoloration.--No change in the general tonality at the end of the first day. Gradual fading is evident at the end of the third day as the flower opens, exhibiting more Yellow Orange Group 19C and less Yellow Orange Group 19A.

Fragrance.--Moderate.

Petals:

Texture.--Thick and leathery.

Shape.--Round.

Form.--Tips slightly recurved.

Arrangement.--Imbricated, with few petaloids in the center.

Persistence.--Drop off cleanly.

Lastingness.--On the plant: Long, 6-7 days. As a cut flower: Long, 7-8 days.

Reproductive parts:

Anthers.--Size: Large. Quantity: Many. Color: Yellow. Arrangement: Regular round styles mixed with occasional petaloids.

Filaments.--Color: Yellow.

Pollen.--Color: Gold Yellow.

Styles.--Color: Reddish.

Claims

1. A new and distinct variety of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its distinctive and unusual yellow-orange flower color, its moderate bloom fragrance, the profusion of glands on stipules, peduncles, leaf axils and upper rachises, vigorous upright habit growth, and large long-lasting blooms.
