Floribunda rose plant named `Jaceve`

Abstract

A new and distinct variety of rose plant of the floribunda class, having very long stems; very good flower production in attractive clusters; long vase life; and attractive, pure light pink flower color.

Description

The present invention relates to a new and distinct variety of rose plant of the floribunda class which was originated by me by crossing an unnamed pink floribunda seedling, with the variety INTERlien, U.S. Plant Pat. No. 7,368.

The primary objective of this breeding was to produce a new rose variety having the high centered, light pink flowers presented in clusters on long stems of the female parent combined with the well-formed sprays, long vase life, and vigorous upright growth habit of the male parent. 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. Very long stems;

2. Very good flower production in attractive clusters;

3. Long vase life;

4. Attractive, pure light pink flower color.

Asexual reproduction of theis 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.

Parentage:

Seed parent.--Unnamed floribunda.

Pollen parent.--INTERlien (U.S. Plant Pat. No. 7,368).

Color.--The upper sides of the petals are Red Group 49D. The reverse sides of the petals are Red Group 49D. The base of each petal has a very small (1/64.times.1/64 inch) greenish white dot at the point of its attachment. The major color on the upper side is Red Group 49D.

Variegations.--Guard petals have greenish white midribs.

Discoloration.--The general tonality at the end of the first day: No change. At the end of the third day: No change. There is no color change through day seven on the plant when the petals shatter.

Fragrance.--Slight.

Petals:

Texture.--Thick.

Shape.--Deltoid to rounded.

Form.--Tips slightly recurved; edges slightly quilled.

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

Persistence.--Drop off cleanly.

Lastingness.--On the plant: Long (7 days). As a cut flower: Very long (13 days).

Reproductive parts:

Anthers.--Size: Medium. Quantity: Many. Color: Yellow. Arrangement: Regular around styles.

Filaments.--Color: Yellow.

Pollen.--Color: Lemon yellow.

Styles.--Color: Greenish white.

Stigmas.--Color: Greenish white.

Form: Bush.

Growth: Very vigirous; upright; branching. At one year, without pruning, JACeve will grow 7-8 feet tall and be 3-4 feet wide. Plant will produce 170-180 stems per square meter of greenhouse.

Foliage:

Number of leaflets on normal mid-stem leaves. --5 or 7.

Size.--Small (3.times.2 inches).

Quantity.--Abundant.

Color.--New foliage: Greyed-red Group 178B but very quickly becoming green. Old foliage: Green Group 136A on upper surface; Green Group 136C on lower surface.

Leaflets:

New wood.--Color: Green. Bark: Smooth.

Old wood.--Color: Green. Bark: Smooth.

Prickles:

Quantity.--On main canes from base: ordinary. On laterals from main canes: ordinary.
