Abstract

A new and distinct Hybrid Tea rose plant is provided that forms abundantly and substantially continuously attractive very double blossoms which display a strong fragrance. The growth habit is bushy, and very strong vegetation is formed. The vegetation is dense and bears a semi-glossy aspect on the upper surface and contrasts nicely with the red blossom coloration. The disease tolerance is very good particularly with respect to black spot. The plant is well suited for providing attractive ornamentation in parks and gardens.

Description

Botanical/commercial classification: Rosa hybrida/Hybrid Tea Rose Plant.
Varietal denomination: cv. Meiceazar.
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 ‘Meivilese’ variety (non-patented in the United States) and ‘Duc de Windsor’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the ‘Deep Secret’ variety (non-patented in the United States).
The parentage of the new variety can be summarized as follows:
(‘Meivilese’בDuc de Windsor’)בDeep Secret’.
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 bushy growth habit with very strong vegetation,
    • (b) forms in abundance on a substantially continuous basis attractive very double pure red blossoms which display a strong fragrance,
    • (c) exhibits very dense semi-glossy dark green foliage that contrasts nicely with the red blossom coloration,
    • (d) displays good disease tolerance particularly with respect to black spot, and
    • (e) is well suited for providing attractive ornamentation in parks and gardens.
The blooming tends to commence medium in the season, during observations to date.
The new variety well meets the needs of the horticultural industry and can be grown to advantage in the landscape where attractive ornamentation is to be provided.
The new variety can be readily distinguished from its ancestors. More specifically, the ‘Meivilese’ variety displays smaller foliage. When compared to the ‘Duc de Windsor’ and ‘Deep Secret’ varieties, the blossoms of the new variety display more petals. The female parent (‘Meivilese’בDuc de Windsor’) has fewer petals than the new variety and is dark pink in coloration.
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 Cannet 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 ‘Meiceazar’.
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 July while budded on Rosa coriifolia var. froebelii understock at Le Cannet des Maures, Var, France.

 DETAILED BOTANICAL DESCRIPTION
