Abstract:
A new and distinct variety of rose plant of the Miniature Class is provided which abundantly forms attractive double yellow blossoms of good color stability. The growth habit is low compact and bushy. Decorative dense dark green semi-glossy foliage is formed that contrasts nicely with the yellow blossoms.

Description:
Botanical/commercial classification:  Rosa hybrida /Miniature Rose Plant. 
     Varietal denomination: cv. Meivoufal. 
     SUMMARY OF THE INVENTION 
     The new variety of Miniature 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) of the new variety was the ‘Savaje’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the product of the pollination of the ‘Playboy’ variety (non-patented in the United States) and the ‘Lavglo’ variety (U.S. Plant Pat. No. 7,136). The parentage of the new variety can be summarized as follows:
 
‘Savaje’×(‘Playboy’×‘Lavglo’).
 
     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 Miniature rose plant of the present invention possesses the following combination of characteristics:
         (a) exhibits a low compact and bushy growth habit,   (b) forms in abundance attractive double yellow blossoms of good color stability, and   (c) forms decorative dense dark green semi-glossy foliage.       

     The bearing is very floriferous. The profusion of yellow blossoms contrast nicely with the dense dark green foliage. 
     The new variety of the present invention can be readily distinguished from its ancestors. For instance, the ‘Savaje’ variety forms larger flowers, the ‘Playboy’ variety forms flowers that are single to semi-double unlike the new variety, and the ‘Lavglo’ variety displays more petals per bloom. The flowers of the ‘Poulgelb’ variety (U.S. Plant Pat. No. 9,401) tend to be smaller and of a slightly lighter yellow coloration. 
     The new variety well meets the needs of the horticultural industry. It is particularly well-suited for pot forcing under greenhouse growing conditions to form an attractive gift plant. 
     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 methods as performed in the South of France has shown that the characteristics of the new variety are strictly transmissible from one generation to another. 
     The new variety has been named the ‘Meivoufal’ variety. 
    
    
     
       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 two years of age and were observed during November while growing on their own roots in greenhouses at LeCannet des Maures, Var, France. Dimensions in centimeters are shown 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 terminology which precedes reference to the chart has been added in some instances to indicate the corresponding colors in more common terms. The description is based on the observation of nine months old specimens of the new variety which were observed during March while growing on their own roots in greenhouses at LeCannet des Maures, Var, France.
