USPP10477P - Rose plant named `Meiparnin` - Google Patents

Abstract

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms attractive very large blossoms that are Cream Yellow and bordered and suffused with light Carmine Rose. Such blossoms additionally exhibit a subtle peach-like fragrance. The plant exhibits medium green and bright foliage, as well as good disease resistance. The new variety is particularly well suited for growing as attractive ornamentation in the landscape or for use when forming cut flowers.

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 cross of the `Meicapula` variety (non-patented in the United States) and the `Korav` variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the `Delboip` variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:

(`Meicapula`×`Korav`)×`Delboip`.

The seeds resulting from the above pollination were sown and 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 very large Cream Yellow blossoms that are bordered and suffused with light Carmine Rose and possess a subtle peach-like fragrance,

(b) exhibits a semi-erect growth habit,

(c) forms attractive medium green and glossy foliage, and

(d) exhibits good disease resistance.

The new variety well meets the needs of the horticultural industry and is particularly well adapted for use as an attractive ornamental plant in an outdoors environment or for cut flower production.

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 `Meiparnin` 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. Dimensions in centimeters are indicated at the bottom of the photograph.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of two year-old plants during June while budded on Rosa froebelii understock and growing outdoors at Le Cannet des Maures, Var, France. The coloration in common terms precedes reference to the chart in some instances.
