USPP9564P - Hybrid tea rose plant named `Meitoifar` - Google Patents

Abstract

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms attractive large double blossoms that are Bengal pink in coloration. Such blossoms are relatively stable in coloration, long-lasting, and commonly are borne in flushes. The petal drop characteristic is good. The plant exhibits a vigorous growth habit and exhibits very good disease resistance including a resistance to Marssonina disease. The new variety is particularly well suited for growing as attractive ornamentation in the landscape.

Description

SUMMARY OF THE INVENTION

The new variety of Hybrid Tea 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 product of the artificial pollination of the `Delset` variety (non-patented in the United States) and the `Eden Rose` variety (U.S. Plant Pat. No. 1,149). The `Delset` variety is marketed under the Versailles trademark. The male parent (i.e., the pollen parent) was the `Kimono` variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:

(`Delset`×`Eden Rose`)×`Kimono`.

The seeds resulting from the above pollination were sown and 120 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 Hybrid Tea rose plant of the present invention possesses the following combination of characteristics:

(a) forms in abundance attractive large long-lasting Bengal Pink blossoms that exhibit a strong fragrance,

(b) exhibits a vigorous growth habit,

(c) exhibits very good disease resistance, and

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

The pink blossoms coloration of the new variety is relatively stable upon the passage of time.

The new variety well meets the needs of the horticultural industry and is particularly well adapted for growing outdoors in parks and gardens.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned techniques in France has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another.

The new variety has been named the `Meitoifar` 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 were two years of age and were observed during June while budded on Rosa froebelii understock and growing outdoors at Le Cannet des Maures, Var, France.
