Abstract:
A new and distinct variety of rose plant is provided which abundantly forms attractive double blossoms having a luminous yellow-orange coloration. The plant exhibits a climbing growth habit, dense medium green semi-glossy foliage, and good vigor. The attractive medium green foliage contrasts nicely with the light-colored blossoms. The new variety is particularly well suited for growing as attractive ornamentation in the landscape such as in parks and gardens.

     BOTANICAL/COMMERCIAL CLASSIFICATION  
       [0002]      Rosa hybrida /Climbing Rose Plant  
       VARIETAL DENOMINATION  
       [0003]     cv. ‘Meivaleir’ 
       SUMMARY OF THE INVENTION  
       [0004]     The new variety of  Rosa hybrida  Climbing 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 ‘Meipalsar’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the product of the pollination of the ‘Korwest’ variety (non-patented in the United States) and the ‘Circus’ variety (U.S. Plant Pat. No. 1,382). The parentage of the new variety can be summarized as follows: 
 
‘Meipalsar’×(‘Korwest’×‘Circus’). 
 
         [0005]     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.  
         [0006]     It was found that the new variety of rose plant of the present invention possesses the following combination of characteristics: 
        (a) exhibits a climbing growth habit,     (b) abundantly forms attractive double blossoms having a luminous yellow-orange coloration,     (c) forms dense medium green semi-glossy foliage that contrasts well with the light-colored blossoms,     (d) exhibits good vigor, and     (e) is particularly well suited for growing as attractive ornamentation in the landscape.        
 
         [0012]     The new variety well meets the needs of the horticultural industry and can be grown to advantage in parks and gardens.  
         [0013]     The new variety of the present invention can be readily distinguished from its ancestors. More specifically, the ‘Meipalsar’ variety displays copper-colored blossoms, the ‘Korwest’ is a Shrub rose plant with ovoid-shaped buds, and the ‘Circus’ variety is a Floribunda rose plant with urn-shaped buds. In contrast the buds of the new variety display a conical configuration.  
         [0014]     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.  
         [0015]     The new variety has been named the ‘Meivaleir’ variety. 
     
    
     BRIEF DESCRIPTION OF THE PHOTOGRAPH  
       [0016]     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 June while budded on  Rosa froebelli  understock and growing in outdoors at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph.

     DETAILED DESCRIPTION  
       [0033]     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 two year-old plants during June while budded on  Rosa froebelli  understock and growing outdoors at Le Cannet des Maures, Var, France. The coloration in more common terms precedes reference to the chart in some instances. Such terminology is to be accorded its ordinary dictionary significance.

The inflorescences               appear on both old and new wood.           bearing   Commonly a shoot will first bear               blooms at its terminus and upper               axils and subsequently may develop               axillary flowers below later in the               same season. In the subsequent year               flowers develop further down along               older portions of the stem.           pedicel   near Yellow-Green Group 146D and               suffused with near Greyed-Red               Group 178C in coloration, and               medium in size with aciculae and               prickles.

Anther color: near Yellow-Orange               Group 17C.               Pollen: present in a moderate               quantity and pale yellow in               coloration.               Pistil number: commonly               approximately 73 on average.               Style color: near Red Group 50A.               Stigma color: near Yellow Group               13A.               petal drop: The petals commonly               detach cleanly under dry growing               conditions, and may persist               somewhat under rainy growing               conditions.               fragrance: none.               lasting quality: long on the plant.               A typical blossom commonly lasts               approximately 7 to 10 days on the               plant depending upon the               environmental conditions. Since the               plant is primarily intended for               providing ornamentation outdoors,               the longevity of the blossoms when               cut and placed in a vase hasnot               been evaluated.               petal shape: the tip is rounded, the               base is obtuse, on the external petals               the margin is reflexed and               undulated, and on the internal petals               the margin is undulated.               receptacle: near Yellow-Green               Group 146D in coloration, and               funnel-shaped in longitudinal               section.           DEVELOPMENT           vegetation   very vigorous and strong.           blooming   abundant.           resistance to   very good with respect to Powdery           diseases   Mildew and Black Spot even late in               the growing season.
