USPP11748P2 - Floribunda rose plant named ‘Meilyzro’ - Google Patents

Abstract

A new and distinct variety of rose plant of the Floribunda Class is provided which abundantly forms attractive double geranium red blossoms in the form of a well-balanced spray. The petals are slightly glossy in appearance. The buds are conical in configuration and are borne on long stems. An erect growth habit is exhibited. The foliage is dark green and contrasts nicely with the geranium red blossoms. The plant is well suited for the production of cut floral sprays under greenhouse growing conditions.

Description

SUMMARY OF THE INVENTION

The new variety of (Rosa hybrida) 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 product of the pollination of the ‘Keinoumi’ variety (U.S. Plant Pat. No. 8,484) and the ‘Olijdum’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was the ‘Meikister’ variety (U.S. Plant Pat. No. 8,267). The parentage of the new variety can be summarized as follows:

(‘Keinoumi’בOlijdum’)בMeikister’.

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 conical buds on long stems in the form of a spray,

(b) forms in abundance attractive geranium red blossoms,

(c) exhibits an erect growth habit, and

(d) forms attractive semi-glossy dark green foliage.

The blossom petals are slightly glossy in appearance. Also, the spray inflorescence is well balanced, and its geranium red coloration contrasts nicely with the dark green foliage.

The new variety well meets the needs of the horticultural industry. It is particularly well-suited for use in the production of cut floral sprays under greenhouse growing conditions.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned methods as performed in France has shown that the characteristics of the new variety are strictly transmissible from one generation to another.

The new variety has been named the ‘Meilyzro’ variety.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). When more common color terms are utilized they are to be accorded customary dictionary significance. The description is based on two year-old specimens of the new variety which were observed during March while budded on Rosa indica understock and growing in greenhouses at LeCannet des Maures, Var, France. Dimensions in centimeters are provided at the bottom of the photograph. The new variety of the present invention has not been tested to date while growing outdoors.
