USPP9233P - Shrub climbing rose plant named `Meitosier` - Google Patents

Abstract

A new and distinct variety of Shrub Climbing rose plant is provided which forms attractive large lightly-fragrant light Mandarin Orange blossoms generally having the configuration of old roses. The blossoming is abundant and the plant reflowers well. The vegetation is vigorous and the plant possesses a climbing growth habit. The plant exhibits very good disease resistance particularly with respect to Marssonina and Black Spot.

Description

SUMMARY OF THE INVENTION

The new variety of Shrub Climbing rose plant of the present invention 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 pollination of the Meipalsar variety (non-patented in the United States) and the Golden Showers variety (U.S. Plant Pat. No. 1,557). The male parent (i.e., the pollen parent) of the new variety was the Light Konigin Lucia variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:

(Meipalsar×Golden Showers)×Licht Konigin Lucia.

The seeds resulting from the above pollination were sown and 116 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 is found that the new variety of Shrub Climbing rose plant possesses the following combination of characteristics:

(a) forms attractive large lightly-fragrant light Mandarin Orange blossoms having an old-rose configuration,

(b) exhibits a propensity for climbing,

(c) exhibits a good ability to reflower, and

(d) is particularly suited for growing as ornamentation in the landscape.

The new variety meets the needs of the horticultural industry. It can be grown to particular advantage as attractive ornamentation in parks, gardens, public areas, and residential landscapes.

The characteristics of the new variety have been found to be homogeneous and stable and are strictly transmissible by asexual propagation carried out in France (e.g., by budding, grafting, and cuttage) from one generation to another.

The new variety has been named the Meitosier 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 described herein were three years of age and were observed during September while budded on Rosa froebelii understock and growing outdoors at Le Cannet des Maures, Var, France.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The terminology preceding the numbered reference to the chart has been added to indicate the corresponding color in more common terms. The description is based on the observation of three year-old specimens of the new variety during June while growing outdoors when budded on Rosa froebelii understock at Le Cannet des Maures, Var, France.
