Hybrid tea rose plant named ‘JACpinap’

Abstract

A hybrid tea rose plant having long stems bearing high centered fragrant flowers; dark green, glossy foliage; vigorous upright growth and resistance to mildew and rust.

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 an unnamed seedling, with the variety JACjubel (U.S. Plant Pat. No. 9,657).

The primary objective of this breeding was to produce a new rose variety having the long stems, high centered bud form and fragrance of the female parent combined with the dark, glossy foliage, excellent foliage health and vigor 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. Glossy, dark green foliage;

2. Vigorous, upright growth;

3. Long cutting stems;

4. High centered flower form;

5. Fragrance; and

6. Novel flower color.

Asexual reproduction of this 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 seedling (unnamed seedling×TANsenfrie (U.S. Plant Pat. No. 5,706)).

Pollen parent.—JACjubel (U.S. Plant Pat. No. 9,657).

Classification:

Botanical.—Rosa hybrida.

FLOWER

Observations made from specimens grown in a garden environment at Somis, Calif. from March 1998 to August 1999.

Blooming habit: Continuous.

Bud:

When half blown, the upper sides of the petals are Orange-Red Group 31B on their outer ⅔'s. The inner ⅓'s are Yellow Group 12C, and the lower sides of the petals are Orange-Red Group 31C on their outer ⅔'s and Yellow Group 12C on the inner ⅓ of a petal.

Sepals.—Color: Green Group 138B. Surface texture: Covered in fine hairs. There are three normally appendaged sepals. There are two unappendaged sepals with hairy edges.

Receptacle.—Color: Yellow-Green Group 147A. Shape: Funnel. Size: Medium (about ¼ inch×{fraction (3/16)} inch). Surface: Smooth.

Peduncle.—Length: Short (about 2 to 2½ inches). Surface: Smooth; with a few glands. Color: Yellow-Green Group 147B. Strength: Stiff; erect.

Bloom:

Size.—Large. Average open size is 4½ inches.

Borne.—Singly.

Stems.—Strength: Strong. Average length is about 16 to 20 inches.

Form.—When first open: High centered. Permanence: Retains its form to the end; outer petals curl back.

Petalage.—Number of petals under normal conditions: 25 to 30.

Color.—The upper sides of the petals are Orange-Red Group 31B on their outer ⅔'s with the inner ⅓ of a petal Yellow Group 12C. The reverse sides of the petals are Orange-Red Group 31C on their outer ⅔'s, with Yellow Group 12C on the inner ⅓ of a petal. The base of each petal has a small ⅛ inch×⅛ inch Yellow Group 13A half moon at the point of attachment on both surfaces. The major color on the upper side is Orange-Red Group 31B.

Variegations.—On the guard petals, along the midrib on the lower surface are occasional greenish-white streaks.

Discoloration.—The general tonality at the end of the first day: No change. At the end of the third day: No change. By day six, there is fading to Orange-Red Group 31D on the outer petal edges. This will extend to all petals by day seven or eight.

Fragrance.—Moderate; anise.

Petals:

Texture.—Thick.
