Abstract:
A new and distinct Floribunda rose plant is provided which forms attractive red-purple blossoms having a yellow eye. The plant exhibits strong vegetation, a compact bushy growth habit, and dark green foliage with a semi-glossy aspect. The disease resistance is excellent particularly with respect to Oidium and Black Spot. The attractive dark green foliage contrasts nicely with the red-purple blossom coloration. 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. Meizerbil. 
   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 ‘The Fairy’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the product of the cross of the ‘Meikrotal’ variety (U.S. Plant Pat. No. 6,087) and the ‘Kormax’ variety (non-patented in the United States. The parentage of the new variety can be summarized as follows:
 
‘The Fairy’×(‘Meikrotal’×‘Kormax’).
 
   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 compact bushy growth habit,   (b) forms attractive red-purple blossoms having a yellow eye,   (c) forms attractive dark green semi-glossy foliage,   (d) displays excellent resistance to disease, and   (e) is well suited for growing as ornamentation in parks and gardens.       

   The disease resistance is particularly good with respect to Oidium and Black Spot. The dark green foliage coloration contrasts nicely with the red-purple blossom coloration. 
   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 new variety can be readily distinguished from its ancestors. For instance, the ‘The Fairy’ variety displays light pink blossoms. The ‘Meikrotal’ variety displays a more bushy growth habit with greater vigor and forms red blossoms with a white eye. The ‘Kormax’ variety forms medium red single 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. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner. 
   The new variety has been named ‘Meizerbil’. 

   
     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 froebelli  understock and growing outdoors at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph together with comparative color information.
