USPP9777P - Floribunda rose plant named `Meipopul` - Google Patents

Abstract

A new and distinct variety of Floribunda rose plant is provided which abundantly forms attractive single scarlet red blossoms on a substantially continuous basis. The plant exhibits a bushy growth habit. Attractive very dense semi-glossy foliage is formed. The new variety is particularly well suited for growing as ornamentation in the landscape. Very good disease resistance also is exhibited.

Description

SUMMARY OF THE INVENTION

The new variety of 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 of the `Korimo` variety (non-patented in the United States) and the `Lenwich` variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was the product of the cross of the `Temple Bells` variety (non-patented in the United States) and the `Moorcap` variety (also known as `Red Cascade`, U.S. Plant Pat. No. 3,962). The parentage of the new variety can be summarized as follows:

(`Korimo`×`Lenwich`) ×(`Temple Bells`×`Moorcap`).

The seeds resulting from the above pollination were sown and 78 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 in abundance attractive single scarlet red blossoms on a substantially continuous basis,

(b) exhibits a bushy growth habit,

(c) forms attractive very dense semi-glossy vegetation, and

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

The new variety has undergone asexual propagation by a number of routes in France, including budding, grafting, and cuttage. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagation from one generation to another in France.

The new variety has been named the `Meipopul` variety.

BRIEF DESCRIPTION OF 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 two years of age and were observed during June while growing on their own roots outdoors at Le Cannet des Maures, Var, France.
