Hybrid tea rose plant 2105-F Strahle cultivar

Abstract

A vigorous rose plant of the hybrid tea class obtained as a seedling from a seed parent entitled "Volare" and a pollen parent entitled "Tonight" provides abundant long-lasting solid velvet red flowers which maintain their true color from flower opening through petal drop on a continuous basis when grown in a greenhouse.

Description

BACKGROUND AND SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of hybrid tea rose plant, a seedling resulting from a definite effort to produce an improvement of this class of rose. The object of the present invention is to provide a rose plant of the hybrid tea class which is capable of freely yielding quality-cut flowers under greenhouse conditions.

The primary features of this new variety which connotates its distinctive advance over previously existing types is its ability to produce an abundance of solid velvet red flowers which remain true after being cut from when they first open through petal drop from a plant which will continuously yield cut flowers under greenhouse conditions.

The variety of rose plant of the present invention was obtained at Carlton, Oreg. as a seedling from a seed parent entitled "Volare" and a pollen parent entitled "Tonight." The crossing was made in 1980, the first seed of the crossing was sewn in January 1981 and the first flower appeared from these seedlings in April 1981.

Asexual reproduction of this new variety shows that its unique characteristics come true to form and is established and transmitted through succeeding propagations through grafting and budding.

DETAILED DESCRIPTION OF THE DISCLOSURE

The following description was made during October 1987 of rose plants of the new and distinct variety growing in a greenhouse at Carlton, Oreg. Color designations are to The Royal Horticulture Society Color Chart.

Flower:

Flower borne.--Singly on normal strength, medium long stems.

Color: Outside: Red Group 53-C. Inside: Red Group 46-B. Opening: it opens up well.

Bloom.--Size when fully open: medium, 21/2" to 4". Petalage: double; from 23 to 25 petals; arranged regularly. Form: high centered at first, becoming open; petal tightly cupped inward; becoming later at maturity loosely rolled outward.

Petals.--Medium leatherly; with inside velvety; outside satiny. Shape: Outer: round; with flat base. Intermediate: round; with apex flat. Inner: round; with apex flat. Color: Color of newly opened flowers: Outer petal: Outer surface: Red Group 53-C. Inner surface: Red Group 45-B. Intermediate petal: Outside surface: Red Group 53-B. Inside surface: Red Group 45-A. Inner petal: Outside surface: Red Group 53-B.5. Inside surface: Red Group 46-A.5. Color of flower three days after opening: Outer petal: Outside surface: Red Purple Group 60-B. Inner petal: Outside surface: Red Purple Group 58-B. Inside surface: Red Group 45-C.

General color effect.--Newly open flower: an overall blending of red color. A little darker on the outside of flower with a satin and velvet mix of texture.

Flowers three days open.--Flower is a solid velvet red color once the stamens start to show.

Behavior.--Petals persist.

Flower longevity.--Cut flowers grown in greenhouse keep at livingroom temperature 9-11 days during October.

Reproductive organs:

Stamens.--Many: arranged regularly about pistils. Filaments: many; most with anthers; medium length. Color: red. Anthers: all open at once; small. Color: yellow. Pollen: abundant; yellow. Pistils: many. Styles: even; medium length; medium weight; bunched. Stigma: white. Ovaries: all enclosed in receptacle. Hips: pear-shaped; moderately smooth; walls medium thickness fleshy; russet. Sepals: permanent; medium length; pear-shaped. Seeds: many; medium size.

Plant:

Foliage.--Leaves: compound of five leaflets; moderately abundant; medium size; moderately leathery. Leaflets: ovate with apex acuminate, base round, margin simply serratedentate.

Claims

1. A new and distinct variety of rose plant of the hybrid tea class obtained as a seedling from a seed parent entitled "Volare" and a pollen parent entitled "Tonight," characterized by its solid velvet red color which is maintained from flower opening through petal drop, and its ability to yield flowers on a continuous basis when grown in a greenhouse, substantially as shown and described.
