rose plant named ‘Meijecycka’

Abstract

A new and distinct Floribunda rose plant is provided which abundantly and nearly continuously forms attractive yellow cup-shaped blossoms commonly displaying approximately 5 to 7 petals. The growth habit is bushy and the adult plant commonly assumes a generally hemispherical configuration. The plant exhibits very strong vegetation, with green semi-glossy foliage that contrasts nicely with the yellow bossom coloration. The blossoms display no fragrance. The new variety is well suited for growing as attractive ornamentation in parks and gardens.

Description

Botanical/commercial classification: Rosa hybrida/Floribunda Rose Plant.

Varietal denomination: cv. Meijecycka.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda 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 a product of the cross of ‘The Fairy’ variety (non-patented in the United States) and an unnamed seedling (non-patented in the United States). The male parent (i.e., the pollen parent) was the product of the cross of the ‘Kortikel’ variety (non-patented in the United States) and the ‘Macshana’ variety (U.S. Plant Pat. No. 5,427). The parentage of the new variety can be summarized as follows:
(‘The Fairy’×Unnamed Seedling)×(‘Kortikel’×Macshana’).

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 Floribunda rose plant of the present invention:

• • (a) exhibits a bushy adult growth habit that commonly is generally hemispherical in configuration,
  • (b) abundantly and nearly continuously forms attractive yellow cup-shaped blossoms commonly displaying approximately 5 to 7 petals,
  • (c) forms very strong vegetation with attractive green semi-glossy foliage that contrasts nicely with the yellow blossom coloration, and
  • (d) is well suited for growing as ornamentation in parks and gardens.

The new variety well meets the needs of the horticultural industry and can be grown to advantage in the landscape where attractive ornamentation is desired. The attractive yellow blossoms commonly initiate blossoming early in the season.

The new variety can be readily distinguished from its ancestors. For instance, ‘The Fairy’ variety displays dissimilar light pink blossoms. The blossoms of the ‘Kortikel’ and ‘Macshana’ varieties commonly possess a substantially larger number of petals than the new variety. The product of the cross of ‘The Fairy’ and unnamed seedling (non-patented in the United States) displays very pale yellow blossoms and a slow repeat blooming characteristic. The product of the cross of the ‘Kortikel’ and ‘Machana’ varieties (non-patented in the United States) displays blossoms having a dissimilar very intense yellow coloration. The new variety also can be readily distinguished from the ‘Medresia’ variety (non-patented in the United States) and the ‘Meibaltaz’ variety (U.S. Plant Pat. No. 8,449). The ‘Medresia’ and ‘Meibaltaz’ varieties display blossoms having considerably more petals. Also, the blossom coloration of the ‘Meidresia’ variety is more intense, and the ‘Meibaltaz’ variety exhibits a more upright growth habit.

The new variety has been found to undergo asexual propagation in France at Le Cannet-des-Maures, 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. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘Meijecycka’.

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 growing on their own roots outdoors at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph together with comparative color information.
