     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Petunia  plant, botanically known as  Petunia  X  hybrida  and hereinafter referred to by the name ‘Dopetsurye’. 
     The new  Petunia  plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new freely branching and early-flowering  Petunia  plants with numerous attractive flowers. 
     The new  Petunia  plant originated from a cross-pollination made by the Inventor in July, 2016 in Rheinberg, Germany of a proprietary selection of  Petunia  X  hybrida  identified as code number TT07-005643-044, not patented, as the female, or seed, parent with a proprietary selection of  Petunia  X  hybrida  identified as code number TT14-008365-024, not patented, as the male, or pollen, parent. The new  Petunia  plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2019. 
     Asexual reproduction of the new  Petunia  plant by terminal vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2019 has shown that the unique features of this new  Petunia  plant are stable and reproduced true to type in successive generations. 
     SUMMARY OF THE INVENTION 
     Plants of the new  Petunia  have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype. 
     The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dopetsurye’. These characteristics in combination distinguish ‘Dopetsurye’ as a new and distinct  Petunia  plant:
         1. Upright and mounding to spreading plant habit.   2. Moderately vigorous to vigorous growth habit.   3. Freely branching habit.   4. Early and freely flowering habit.   5. Large pale yellow green and greenish yellow-colored flowers.   6. Good garden performance.       

     Plants of the new  Petunia  can be compared to plants of the female parent selection. In side-by-side comparisons, plants of the new  Petunia  differ primarily from plants of the female parent selection in growth habit as plants of the new  Petunia  are more vigorous than and not as compact as plants of the female parent selection. In addition, flower color of plants of the new  Petunia  is more intense than and not as muted as flower color of plants of the female parent selection. 
     Plants of the new  Petunia  can be compared to plants of the male parent selection. In side-by-side comparisons, plants of the new  Petunia  differ primarily from plants of the male parent selection in growth habit as plants of the new  Petunia  are more vigorous than and not as compact as plants of the male parent selection. In addition, flower color of plants of the new  Petunia  is more intense than and not as muted as flower color of plants of the male parent selection. 
     Plants of the new  Petunia  can be compared to plants of  Petunia  X  hybrida  ‘Sunsurf Kitatsu’, disclosed in U.S. Plant Pat. No. 25,400. In side-by-side comparisons, plants of the new  Petunia  and ‘Sunsurf Kitatsu’ differ primarily in the following characteristics:
         1. Plants of the new  Petunia  are more compact than and not as vigorous as plants of ‘Sunsurf Kitatsu’.   2. Plants of the new  Petunia  are more freely flowering than plants of ‘Sunsurf Kitatsu’.   3. Plants of the new  Petunia  have larger flowers than plants of ‘Sunsurf Kitatsu’.       

    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPH 
       The accompanying colored photograph illustrates the overall appearance of the new  Petunia  plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new  Petunia  plant. 
       The photograph is a side perspective view of a typical flowering plant of ‘Dopetsurye’ grown in a container. 
     
    
    
     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photograph and following observations, measurements and values describe plants grown during the spring in 22-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typical of commercial  Petunia  production.
