Seedling rose plant

Abstract

A new and distinct bi-colored rose plant for greenhouse culture and cut flower production, distinguished by the Talisman coloration of its medium sized blooms which is intense and brilliant both in the bud stage and as an open flower, and by its above average vase life and keeping qualities as a cut flower. This rose plant has a vigorous growth habit with a continuous and abundant production of flowers, borne singly on stems of medium length, and an abundance of dark green, glossy foliage.

Description

BACKGROUND OF THE NEW PLANT

This new rose plant originated as a seedling resulting from a cross of Cotillion (U.S. Plant Pat. No. 2,978) by Hoosier Gold (U.S. Plant Pat. No. 3,544) made at Richmond, Ind., in March 1973, with the object of producing a more vivid bi-colored flower than its seed parent while maintaining the vigorous growth of the pollen parent and the disease resistant characteristic of both parents. This rose was discovered by me in October 1974 and was reproduced by me, by budding, at Richmond, Ind., to determine and test its true characteristics, and propagation in a like manner through successive generations has demonstrated that the objectives of the original crossing have been accomplished and appear to be firmly fixed, holding true from generation to generation.

This plant is now being commercially propagated, by budding, at Hamilton City, Calif.

DESCRIPTION OF THE DRAWING

My new variety of rose plant is illustrated by the accompanying full color photographic drawing which shows several stages of its buds, a newly opened flower, and a full face view of a fully opened, three day bloom. The drawing also shows specimens of young wood and typical leaves of the blooming plant. At the bottom left of the drawing, the outside (top row) and inside surfaces of the outside, intermediate, and inner petals of a newly opened flower are shown, and similarly, at the bottom right of the drawing, the outside (bottom row) and inside petal surfaces of a three-day opened bloom are shown. The colors shown are as nearly true as can be reasonably expected to be reproduced by conventional photographic procedures.

B. This description was made from observations of a rose that was opened for three days in greenhouse in the month of June 1980:

Outside petals.--Outer surface -- Indian Yellow 6/1 (W) at the base gradually changing to 6/2 (W) toward the top and slightly tinted with Brick Red 016/2 (W) at the tip. Inside surface -- Indian Yellow 6/1 (W) at the base gradually changing to Brick Red 016/1 (W) at the top.

Inner petals.--Outside surface -- Indian Yellow 6/1 (W) at the base gradually changing to Indian Yellow 6/2 (W) at the top. Inside surface -- Indian Yellow 6/1 (W) at the base gradually changing to Brick Red 016/1 (W).

General color effect of open bloom:

Newly opened flower.--Predominantly Brick Red 016 (W).

Three days opened bloom.--The predominant coloration is Brick Red 016/1 (W).

Persistence: The petals hang on and dry.

Lasting quality: Five to seven days in February for cut roses grown in greenhouse and kept at living room temperatures.

REPRODUCTIVE ORGANS

Stamens: Many in number and regularly arranged about the pistils.

Filaments.--Some are short and some are of medium length, most with anthers. Color: Indian Yellow 6/3 (W).

Anthers.--Medium in size and all open at once. Color: Indian Yellow 6/2 (W) with outside edge Indian Yellow 6 (W).

Pollen.--Abundant in quantity. Color: Straw Yellow 604/2 (W).

Pistils: Medium in number.

Styles.--Of medium length and very uneven, thin in size and bunched. Color: Empire Yellow 603/3 (W).

Stigmas.--Color -- Creamy White Plate 2 (K).

Ovaries: No hips observed.

Seeds: None.

The most distinctive and novel feature of this seedling rose is the intense and brilliant bi-color of the bloom both in the bud stage and as an open flower. This seedling also distinguishes itself further by exhibiting very good vase life and keeping qualities as a cut flower.

This new plant is considered to be a material improvement over its seed parent, Cotillion, in that the flower color is more vivid and brilliant and the abundance of dark green, glossy foliage further accentuates and enhances the brilliance of the flower color. Also, the growing habits of this plant are more responsive and vigorous than those of the seed parent even under the poor light conditions of winter months.

With respect to the pollen parent, Hoosier Gold, this new plant has been found to have better bud formation and longer stems as a cut flower. Also, this new seedling would be classed categorically as of Talisman coloration, whereas Hoosier Gold is a solid yellow color flower.

Claims

1. A new and distinct variety of rose plant substantially as herein shown and described, characterized by its abundant and continuous production of medium sized flowers of Talisman coloration borne on medium strong stems of medium length, and by its vigorous and responsive growth habits under the poor light conditions of winter months.
