USPP13757P2 - Floribunda rose plant named ‘Meicinelle’ - Google Patents

Abstract

A new and distinct variety of Floribunda rose plant is provided which abundantly forms on a continuous basis semi-double blossoms that are red spotted with white in coloration. The plant exhibits a bushy and vigorous well-formed growth habit, and good resistance to Marsonia rosae and Phragmidium. The attractive very dense medium green foliage contrasts nicely with the blossom coloration. The new variety is particularly well suited for growing as attractive ornamentation in parks and gardens.

Description

BOTANICAL CLASSIFICATION

Rosa hybrida.

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) was the product of the cross at the ‘Meidanu’ variety (non-patented in the United States) and the ‘Macev’ variety (U.S. Plant Pat. No. 2,424). The ‘Macev’ variety sometimes is known as the ‘Evelyn Fison’ variety. The male parent (i.e., the pollen parent) was the ‘Tantide’ variety (non-patented in the United States). The ‘Tantide’ variety sometimes is known as the ‘Glad Tidings’ variety. The parentage of the new variety can be summarized as follows:

‘(Meidanu’בMacev’)בTantide’.

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 Floribunda rose variety of the present invention

(a) Exhibits a bushy and vigorous well-formed growth habit,

(b) Abundantly forms on continuous basis attractive semi-double blossoms that are red spotted with white in coloration,

(c) Forms very dense medium green foliage with a dull aspect that contrasts well with the blossom coloration, and

(d) Is particularly well suited for growing as ornamentation in parks and gardens.

The disease resistance is good with respect to Marsonia rosae and Phragmidium.

The new variety well meets the needs of the horticultural industry and can be used to advantage for growing in the landscape where attractive ornamentation is desired.

The new variety of the present invention can be readily distinguished from its ancestors. For instance, the flowers of the ‘Meidanu’ variety are of a darker and more uniform coloration, the flowers of the ‘Macev’ variety also lack bicoloration, and ‘Tantide’ variety exhibits darker foliage and a taller growth habit.

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 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.

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

BRIEF DESCRIPTION OF THE 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 approximately eighteen months of age and were observed during June while budded on Rosa froebelli understock and growing outdoor at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of eighteen month-old plants during October while budded on Rosa froebelli understock and growing outdoors at Le Cannet des Maures, Var, France.
