Abstract

A new and distinct variety of rose plant of the Hybrid Tea Class is provided which abundantly forms on a nearly continuous basis attractive highly fragrant blossoms that are near white suffused with orange-pink in coloration. The growth habit is vigorous and erect. Very decorative dark green and semi-glossy foliage is formed that contrasts nicely with the blossom coloration. The fragrance of the blossoms is strong. The new variety is particularly well suited for forming attractive ornamentation in the landscape.

Description

Botanical/commercial classification: Rosa hybrida/Hybrid Tea Rose Plant.

Varietal denomination: cv. Meigroupy.

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 product of the cross of the ‘Meilivar’ variety (U.S. Plant Pat. No. 7,541) and the ‘Sunbelt’ variety (non-patented in the United States. The male parent (i.e., the pollen parent) was the ‘Meivildo’ variety (U.S. Plant Pat. No. 6,895). The parentage of the new variety can be summarized as follows:
(‘Meilivar’×‘Sunbelt’)×‘Meivildo’.

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 Hybrid Tea rose plant of the present invention possesses the following combination of characteristics:

- (a) exhibits a vigorous erect growth habit,
- (b) abundantly forms on a nearly continuous basis attractive highly fragrant blossoms that are near white suffused with orange-pink in coloration,
- (c) forms attractive dark green decorative semi-glossy foliage that contrasts well with the blossom coloration, and
- (d) is particularly well suited for growing as attractive ornamentation in the landscape.

The tolerance to diseases of the new variety is good.

The new variety of the present invention can be readily distinguished from its parental varieties. The ‘Meilivar’ variety forms blossoms that are intense yellow in coloration. The blossoms of the ‘Sunbelt’ variety also are yellow in coloration. The ‘Meivildo’ male parent forms pink blossoms having serration on the edges of the petals.

Also, the new variety can be distinguished from the ‘Meidiaphaz’ variety (non-patented in the United States) and the ‘Meifassel’ variety (U.S. Plant Pat. No. 16,951, granted Aug. 8, 2006). More specifically, the ‘Meidiaphaz’ variety displays dissimilar high-pointed buds, and the ‘Meifassel’ variety forms dissimilar high-centered blossoms.

The new variety well meets the needs of the horticultural industry and can be grown to advantage 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 ‘Meigroupy’ 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 one and one-half years of age and were observed during November while budded on Rosa froebelli understock and growing outdoors at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph.
