Abstract

A new and distinct variety of Hybrid Tea rose plant is provided that forms at mid-season abundantly and substantially continuously attractive highly fragrant Orient Pink blossoms. The buds are substantially conical-shaped. The vegetation is very strong and attractive glossy dark green foliage is formed. Excellent resistance to Marsonia is displayed. The plant is particularly well suited for providing attractive ornamentation in the landscape.

Description

Botanical/commercial classification: Rosa hybrida/Hybrid Tea Rose Plant.
Varietal denomination: cv. Meitroni.
SUMMARY OF THE INVENTION
The new variety of Rosa hybrida 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) was the product of the cross of the ‘Tanrowisa’ variety (non-patented in the United States) and the ‘Meimalyna’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the ‘Harkuly’ variety (non-patented in the United States). The ‘Harkuly’ variety sometimes is known as the ‘Margaret Merril’ variety.
(‘Tanrowisa’בMeimalyna’)בHarkuly’.
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 Hybrid Tea rose plant of the present invention:
    • (a) forms very strong vegetation,
    • (b) forms large substantially conical-shaped buds,
    • (c) forms at mid-season abundantly and substantially continuously attractive highly fragrant Orient Pink blossoms,
    • (d) displays attractive glossy dark green foliage,
    • (e) displays excellent resistance to Marsonia,
    • (f) is particularly well suited for providing attractive ornamentation in the landscape.
The new variety well meets the needs of the horticultural industry and can be grown to advantage in parks and gardens. The disease tolerance is good particularly with respect to Marsonia.
The new variety can be readily distinguished from its ancestors. For instance, the blossom coloration is considerably different from that of the ‘Tanrowisa’, ‘Meimalyna’, and ‘Harkuly’ varieties. More specifically, the ‘Tanrowisa’ variety forms blossoms that are pink on the upper surface and silver on the under surface, the ‘Meimalyna’ variety forms medium red blossoms, and the ‘Harkuly’ variety forms white blossoms.
The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and the use of cuttings. 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 ‘Meitroni’.
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 approximately one year of age and were observed during May while budded on Rosa laxa understock and growing outdoors at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph, as is a standard color comparison.

 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 one-year-old plants during May which were budded on Rosa laxa understock and growing outdoors at Le Cannet des Maures, Var, France.
