Hybrid Tea Rose plant named ‘Meifaissel’

Abstract

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms on a nearly continuous basis attractive white high-pointed blossoms having a very strong fragrance. The plant exhibits a semi-erect growth habit, and dense dark green foliage with a semi-glossy aspect. Good tolerance to Oidium and Black Spot is displayed. The attractive dark green foliage contrasts nicely with the pure white blossom coloration. The new variety is particularly well suited for growing as attractive ornamentation in the landscape.

Description

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

Varietal denomination: cv. ‘Meifaissel’.

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 ‘Meban’ variety (non-patented in the United States). The ‘Meban’ variety sometimes is known as the ‘White Knight’ variety. The male parent (i.e., the pollen parent) was the product of the cross of the ‘Poulari’ variety (U.S. Plant Pat. No. 9,274) and the ‘Lady Sylvia’ variety (non-patented in the United States). The ‘Poulari’ variety sometimes is known as the ‘Karen Blixen’ variety. The parentage of the new variety can be summarized as follows:
‘Meban’×(‘Poulari’בLady Sylvia’).

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 the present invention

• • (a) exhibits a very vigorous semi-erect growth habit,
  • (b) abundantly forms on a nearly continuous basis attractive white high-centered blossoms having a very strong fragrance,
  • (c) forms dense dark green foliage having a semi-glossy aspect that contrasts well with the blossom coloration, and
  • (d) is particularly well suited for growing as attractive ornamentation in the landscape.

The tolerance to Oidium and Black Spot is good, and the white blossom coloration is stable. The very strong blossom fragrance is a combination of sweet rose and banana.

The new variety well meets the needs of the horticultural industry and can be grown to advantage in parks and gardens where attractive ornamentation is desired.

The new variety can be readily distinguished from its ancestors. For instance, the ‘Meban’ variety forms white blossoms having approximately 33 petals having no fragrance and light green foliage. The ‘Poulari’ variety forms blossoms in clusters having a very slight fragrance and medium green glossy foliage. The ‘Lady Sylvia’ variety forms light pink blossoms.

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 ‘Meifaissel’, and is being marketed under the QUEEN MARY 2 trademark.

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 18 months of age and were observed during September 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.

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 eighteen month-old plants during September while budded on Rosa froebelli understock and growing outdoors at Le Cannet des Maures, Var, France.
