Floribunda rose plant names `Olysko`

- The Conard-Pyle Company

A new and distinct variety of Floribunda rose plant is provided which abundantly forms attractive double intense yellow blossoms which are long-lasting when cut and placed in a vase. The foliage is dark green and exhibits a glossy upper surface that contrasts well with the light blossom coloration. The plant exhibits vigorous vegetation and exhibits an erect growth habit. The new variety is well suited for cut flower production under greenhouse growing conditions.

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 Korflapei variety (U.S. Plant Pat. No. 6,695). The male parent (i.e., the pollen parent) of the new variety was the Ruidriko variety (U.S. Plant Pat. No. 7,362). The parentage of the new variety can be summarized as follows:

Korflapei.times.Ruidriko.

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 double blossoms having an intense yellow coloration,

(b) forms attractive vigorous dark green foliage having a glossy upper surface.

(c) exhibits an erect growth habit, and

(d) is well suited for cut flower production in a greenhouse.

As demonstrated in France, the new variety undergoes asexual propagation of 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.

The new variety has been named the Olysko 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 two years of age and were observed during November while budded on Rosa indica understock and growing in greenhouses at Le Cannet des Maures, Var, France.
