Floribunda rose plant named `Olytel`

Abstract

A new and distinct variety of Floribunda rose plant is provided which abundantly forms attractive double bicolored blossoms which are long lasting when cut and placed in a vase. The blossoms are light Cardinal Pink suffused with Turk Red on the upper side and light Cream Yellow more or less edged and suffused with light Cardinal Pink on the under side. The plant exhibits vigorous vegetation and exhibits a bushy growth habit. The new variety is well adapted for greenhouse forcing and is particularly well suited for cut flower production. Good resistance to cryptogamic diseases also is exhibited.

Description

SUMMARY OF THE INVENTION

The new variety of Floribunda rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new variety was the Fantasia variety (U.S. Plant Pat. No. 590). The male parent (i.e., the pollen parent) of the new variety was the Vivaldi variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:

FANTASIA.times.VIVALDI.

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new variety of Floribunda rose plant of the present invention possesses the following combination of characteristics:

(a) forms in abundance attractive long-lasting bicolored double blossoms which are light Cardinal Pink suffused with Turk Red on the upper side and light Cream Yellow more or less suffused with light Cardinal Pink on the under side,

(b) forms bronze green adult wood,

(c) forms vigorous vegetation,

(d) exhibits a bushy growth habit,

(e) is particularly well suited for forcing and cut flower production in a greenhouse, and

(f) is not particularly affected by cryptogamic diseases.

The new variety undergoes asexual propagation by a number of routes, including budding, grafting, cuttage, etc. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagation from one generation to another in France and in the United States.

The new variety has been named the Olytel variety.

BRIEF DESCRIPTION OF PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were one year of age and were observed during February while budded on Rosa indica understock and growing in greenhouses at Cap d'Antibes, France.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of the Royal Horticultural Society (R.H.S. Colour Chart). The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The description is based on one year old specimens of the new variety during February while budded on Rosa indica understock and growing in greenhouses at Cap d'Antibes, France.

Class: Floribunda (Sweetheart).
