Abstract

A new and distinct variety of Miniature Rose plant, herein referred to by its cultivar name, ‘MEIBENBINO’, is provided which forms very abundantly on a nearly continuous basis attractive, cup-shaped, red colored blossoms. Attractive, glossy, very dense foliage is formed, which contrasts beautifully with the blossoms. The disease tolerance is very good, particularly against Black Spot. The new variety is well suited for proving attractive ornamentation in the landscape.

Description

Botanical/commercial classification:

Latin name: Rosa hybrida.

Common name: Miniature Rose Plant.

Varietal denomination: ‘MEIBENBINO’.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Community Plant Variety Rights application number 2017/2341 filed on Sep. 21, 2017, which is incorporated herein by reference in its entirety for all purposes.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Miniature 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) was the product of a cross of the ‘MEIPAONIA’ variety (non-patented in the United States) and an ‘UNNAMED SEEDLING’ variety. The male parent (i.e., the pollen parent) was the ‘RADTKO’ variety (U.S. Plant Pat. No. 16,202).

The parentage of the new variety can be summarized as follows:
(‘MEIPAONIA’ x ‘UNNAMED SEEDLING’) x ‘RADTKO’

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 Miniature Rose plant of the present invention possesses the following combination of characteristics:

- (a) very abundantly and nearly continuously forms attractive, cup-shaped, red colored blossoms,
- (b) forms attractive, very dense, glossy foliage,
- (c) exhibits very good tolerance to diseases, particularly against Black Spot, and
- (d) is well suited for providing attractive ornamentation.

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 ‘RADTKO’ variety (i.e., the pollen parent) is a shrub rose plant/bedding rose plant, whereas the new variety is a miniature rose plant. The (‘MEIPAONIA’ x ‘UNNAMED SEEDLING’) variety (i.e., the seed parent) exhibits bigger flowers with more petals compared to the new variety and provides ocher colored blossoms, whereas the new variety exhibits red colored blossoms. The ‘MEIPAONIA’ variety (i.e., a parent of the seed parent) exhibits ocher colored blossoms, whereas the new variety exhibits red colored blossoms.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and the use of cuttings. Asexual propagation by the above-mentioned techniques in 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 ‘MEIBENBINO’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photographs show 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 approximately one year of age and were observed during July while budded on their own roots and growing outdoors at Le Cannet des Maures, Var, France. Standard color information and dimensions in centimeters are included at the bottom of the photograph.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Color Chart), 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 one-year-old specimens of the new variety during July while budded on their own roots and growing outdoors at Le Cannet des Maures, Var, France.
