Abstract

A new and distinct Hybrid Tea rose plant is provided that commonly commences blooming early in the season and forms abundantly and substantially continuously attractive pure white very double blossoms which display a very strong fragrance. The growth habit is semi-erect, and very strong vegetation is formed. The vegetation is decorative and very dense and bears a glossy aspect on the upper surface. No particular disease problem has been observed. The plant is particularly well suited for providing attractive ornamentation in parks and gardens.

Description

Botanical/commercial classification: Rosa hybrida/Hybrid Tea Rose Plant.
Varietal denomination: cv. Meicalanq.
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 ‘Typhoon’ variety (non-patented in the United States) and ‘Meivildo’ variety (U.S. Plant Pat. No. 6,895). The male parent (i.e., the pollen parent) was the ‘Meimagarmic’ variety (U.S. Plant Pat. No. 5,067).
The parentage of the new variety can be summarized as follows:
(‘Typhoon’בMeivildo’)בMeimagarmic’.
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) displays a semi-erect growth habit with strong vegetation,
    • (b) forms in abundance on a substantially continuous basis attractive pure white very double blossoms which display a very strong fragrance,
    • (c) exhibits decorative very dense glossy dark green foliage, and
    • (d) is particularly well suited for providing attractive ornamentation in parks and gardens.
The blooming tends to commence early in the season, during observations to date.
The new variety well meets the needs of the horticultural industry and can be grown to advantage where attractive ornamentation is to be provided.
The new variety can be readily distinguished from its ancestors. For instance, the blossom coloration is considerably different from that of the ‘Typhoon’ and ‘Meivildo’ varieties. More specifically, the ‘Typhoon’ variety forms yellow blossoms and the ‘Meivildo’ variety forms neyron pink blossoms. Also, the blossoms of the ‘Meimagarmic’ variety are of a dissimilar empire yellow coloration and are suffused and edged with an amaranth red flush.
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 at Le Gannet des Maures, Var, 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. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.
The new variety has been named ‘Meicalanq’.

The rose plants of the new variety were approximately two years of age and were observed during October while budded on Rosa froebelli understock and growing outdoors at Le Cannet 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 description is based on the observation of two-year-old plants during October which were budded on Rosa froebelli understock and growing outdoors at Le Cannet des Maures, Var, France.
