Abstract

A new and distinct variety of bedding rose plant, herein referred to by its cultivar name, ‘MEIDYCEUS’, is provided which forms on a nearly continuous basis attractive, cup shaped, very pure white double flowers. Attractive, glossy foliage is formed, which contrasts beautifully with the blossoms. A bushy growth habit is displayed. The disease tolerance is very good, particularly against black spot and Oidium. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

Botanical/commercial classification:
Latin name: Rosa hybrida.
Varietal denomination: ‘MEIDYCEUS’.
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority to Plant Breeders' Right Application Number 2019/2397, which was filed at Community Plant Variety Office in the European Union on Sep. 24, 2019, the contents of which are hereby incorporated by reference for all purposes.
SUMMARY OF THE INVENTION
The new variety of Rosa hybrida 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) was the ‘THE FAIRY’ variety (non-patented). The male parent (i.e., the pollen parent) was the ‘AUSMAS’ variety (non-patented).
The parentage of the new variety can be summarized as follows:
‘THE FAIRY’ x ‘AUSMAS’
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 rose plant of the present invention possesses the following combination of characteristics:
    • (a) forms attractive, cup shaped, very pure white double flowers,
    • (b) forms attractive, glossy foliage, and
    • (c) exhibits good resistance to diseases, particularly against black spot and Oidium.
The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.
The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the ‘THE FAIRY’ variety (i.e., the seed parent) displays pink colored blossoms and the ‘AUSMAS’ variety (i.e., the pollen parent) displays yellow colored blossoms, whereas the new variety displays very pure white colored flowers. Moreover, the new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘Meiradena’ variety (U.S. Plant Pat. No. 26,790) displays less petals and a less pure white flower color compared to the new variety.
The new variety has been found to undergo asexual propagation in Le Cannet des Maures, Var, France by a number of routes, including softwood cuttings and grafting t-bud. Asexual propagation by the above-mentioned techniques in Le Cannet des Maures, Var, France has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.
The new variety has been named ‘MEIDYCEUS’.
The first offer for sale of the new variety was Mar. 31, 2019 in France by the inventor or another who obtained the new variety directly or indirectly from the inventor.

 DETAILED BOTANICAL DESCRIPTION
The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart, 2001 edition), London, England. 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 the observation of two-year-old specimens of the new variety during July while budded on Rosa Laxa and growing outdoors at Le Cannet des Maures, Var, France.
