Rose plant--Meikiji variety

Abstract

A new and distinct variety of Floribunda rose plant is provided which abundantly and continuously forms attractive long-lasting fully double bicolored blossoms. The blossoms are French Rose edged and suffused with Rose Bengal. The plant exhibits vigorous vegetation, is well-balanced, is semi-erect, and exhibits a relatively quick blooming cycle. The new variety is particularly well suited for the decoration of parks and gardens. Good resistance to cryptogamic diseases 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) of the new variety was the Meicadol variety (nonpatented in the United States). The male parent (i.e., the pollen parent) of the new variety was the Magic Carrousel variety (U.S. Plant Pat. No. 3,601). The parentage of the new variety can be summarized as follows:

Meicadol.times.Magic Carrousel.

The seeds resulting from the above pollination were sown and 38 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.

The new variety meets well the needs of the horticultural industry for all uses, and is particularly well suited for growing in parks and gardens. Well-balanced plants are formed which are semi-erect and bloom profusely and continuously in relatively quick cycles.

It was found that the new variety of Floribunda rose plant of the present invention possesses the following combination of characteristics:

(a) forms abundantly and continuously attractive long-lasting bicolored double blossoms which are French Rose edged and suffused with Rose Bengal,

(b) forms medium green adult wood,

(c) forms vigorous vegetation,

(d) is particularly well suited for the decoration of parks and gardens, and

(e) is not particularly affected by cryptogamic diseases.

The new variety has been found to undergo asexual propagation by a number of conventional routes, including budding, grafting, and cuttage. Asexual reproduction by the above mentioned methods as performed in France shows that the characteristics of the new variety are strictly transmissible from one generation to another and appear to be firmly fixed.

The new variety has been named the Meikiji 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 three years of age and were observed during June while budded on Rose froebelli understock and growing outdoors at LeCannet-des-Maures, Var, France.
