Miniature rose plant named Meimagul

Abstract

A new and distinct variety of rose plant of the Miniature Class is provided which abundantly forms attractive bicolored double blossoms which exhibit a generally velvet red appearance with some yellow coloration when viewed from above. The plant is bushy, and forms very vigorous vegetation that is dense and semi-dull in appearance. The blossoms possess no fragrance. The plant is well adapted to pot forcing under light, and grows well on its own roots. The foliage is medium green in coloration and tends to be well-pointed.

Description

SUMMARY OF THE INVENTION

The new variety of Miniature 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 pollination of the Bonfire Night variety (non-patented in the United States) by the Meialfi variety (U.S. Plant Pat. No. 2,140). The Meialfi variety sometimes is known as the Zambra variety. The male parent (i.e., the pollen parent) of the new variety was the RUGUL variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:

(BONFIRE NIGHT.times.MEIALFI).times.RUGUL.

The seeds resulting from the above pollination were sown and 301 plantlets 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 Miniature rose plant of the present invention possesses the following combination of characteristics:

(a) forms in abundance attractive double bicolored blossoms which exhibit a generally velvet red appearance with some yellow coloration when viewed from above,

(b) forms medium-green pointed foliage,

(c) exhibits a bushy growth habit,

(d) is well adapted to pot forcing under light, and

(e) grows well on its own roots.

The new variety well meets the needs of the horticultural industry. It is particularly well-suited for use as attractive ornamentation in the landscape.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, cuttage. Asexual propagation by cuttings as performed in France has shown that the characteristics of the new variety are strictly transmissible from one generation to another.

The new variety has been named the Meimagul 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 two years of age and were observed during September while growing on their own roots indoors at LeCannet 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 which precedes reference to the chart has been added to indicate the corresponding colors in more common terms. The description is based on two year-old specimens of the new variety which were observed during September while growing on their own roots indoors at LeCannet des Maures, Var, France.
