Abstract

A new rose plant cultivar intended for greenhouse culture for the production of cut flowers, distinguished by its uniform growth and cane quality with less blind wood, the exceptional vase life of its relatively slow opening flowers, when ready to cut, which makes them easier to handle in periods of high production, the exceptional timing characteristic and opening flower form of its deep red flowers, and the good response of this plant to lower temperature rose growing conditions.

Description

BACKGROUND OF THE NEW PLANT

This new rose plant originated as a seedling resulting from my cross of "Forever Yours" (U.S. Plant Pat. No. 2,443) with "Love Affair" (U.S. Plant Pat. No. 3,287) at Richmond, Ind., in the spring of 1970 with the object of developing a rose that would combine the good qualities of both parents and also have good response to the lower temperature growing conditions necessitated by current energy problems.

My new plant produced its first flower in the spring of 1971 and because of the beautiful solid red coloring of its blooms, this plant was selected for reproduction and test. Asexual propagation of this new plant by budding was carried on at Richmond, Ind., under my direction and several years of observation of the progeny of this plant and succeeding propagations by grafting at Pleasanton, Calif., have demonstrated that this new rose variety has fulfilled my objectives and that its distinctive characteristics are firmly fixed and hold true from generation to generation.

DESCRIPTION OF THE DRAWING

This new variety of rose plant is illustrated by the accompanying full color photographic drawing which shows the form of the fully opened flower and three stages of the buds, typical leaves of this variety, a specimen of young wood with leaves and a specimen of old stem, and a side view showing the reproductive organs of a flower after the petals have been removed, the colors shown being as nearly true as can be reasonably done by conventional photographic procedures.

My new variety of rose plant is an improvement over its seed parent "Forever Yours" in that it has less blind wood, improved opening flower form and better vase life. The flowers of the new plant are also slower opening, when ready to cut, and are thus easier to handle than those of its parent during periods of high production.

This new variety is better than its pollen parent "Love Affair" in at least two major respects. It is uniform in growth and cane quality and it does not have the lack of uniformity of timing often exhibited by its pollen parent.

The uniform growing characteristic of this new rose together with its exceptional timing and vase life enhance its commercial value as a producer of cut flowers of superior character.

Claims (1)

I claim:

1. A new and distinct cultivar of rose plants "Forever Yours" × "Love Affair" substantially as herein shown and described, characterized by its uniform growth and cane quality with less occurrence of blind wood, its uniform timing and improved vase life, and the slower opening of its buds when ready to cut and its improved opening flower form.
