Rose plant--Meinagre variety

Abstract

A new and distinct variety of Floribunda rose plant is provided which abundantly and continuously forms attractive long lasting currant red semi-double blossoms. The plant is bushy, low, compact, and well-balanced, and exhibits vigorous vegetation. 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 Meinececa variety (nonpatented in the United States). The male parent (i.e., the pollen parent) of the new variety was the Lilli Marlene variety U.S. Plant Pat. No. 1,986). The parentage of the new variety can be summarized as follows:

Meinececa.times.Lilli Marlene.

The seeds resulting from the above pollination were sown and 96 small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identificaiton 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.

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

(a) forms attractive long lasting semi-double blossoms which are currant red in coloration,

(b) forms vigorous vegetation,

(c) exhibits a bushy, low, compact and well-balanced growth habit, and

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

The new variety undergoes asexual propagation by various routes, including budding, grafting, cuttage, etc. Asexual reproduction by the above mentioned methods as performed in France shows that the characteristics of the new variety are strictly transmissable from one generation to another.

The new variety has been maned the Meinagre 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 observed during September while budded on Rosa froebelli understock and growing outdoors at LeCannet-des-Maures, Var, France.
