Title: Petunia plant named ‘Sunsurfpitora’

Description:
Botanical designation:  Petunia×hybrida.    
     Cultivar denomination: ‘SUNSURFPITORA’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Petunia  plant, botanically known as  Petunia×hybrida  and hereinafter referred to by the name ‘Sunsurfpitora’. 
     The new  Petunia  plant is a product of a planned breeding program conducted by the Inventors in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new freely branching  Petunia  plants with mounding habit and attractive flower coloration. 
     The new  Petunia  plant originated from a cross-pollination made by the Inventors in April, 2004 in Higashiomi, Shiga, Japan of a proprietary selection of  Petunia×hybrida  identified as code name Px256-03, not patented, as the female, or seed, parent with a proprietary selection of  Petunia×hybrida  identified as code name FTSMP, not patented, as the male, or pollen, parent. The new  Petunia  plant was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Higashiomi, Shiga, Japan in September, 2008. 
     Asexual reproduction of the new  Petunia  plant by terminal cuttings in a controlled environment in Higashiomi, Shiga, Japan since October, 2008, 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 environmental conditions and cultural conditions. 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 ‘Sunsurfpitora’. These characteristics in combination distinguish ‘Sunsurfpitora’ as a new and distinct  Petunia  plant:
         1. Compact and mounding plant habit.   2. Vigorous growth habit.   3. Freely branching habit.   4. Early and freely flowering habit.   5. Long flowering period.   6. Medium-sized salmon pink-colored flowers.   7. Good garden performance.       

     Plants of the new  Petunia  can be compared to plants of the female parent selection. Plants of the new  Petunia  differ primarily from plants of the female parent selection in the following characteristics:
         1. Plants of the new  Petunia  have smaller flowers than plants of the female parent selection.   2. Plants of the new  Petunia  and the female parent selection differ in flower color as plants of the female parent selection have darker pink-colored flowers.       

     Plants of the new  Petunia  can be compared to plants of the male parent selection. Plants of the new  Petunia  differ primarily from plants of the male parent selection in flower size as plants of the new  Petunia  have larger flowers than plants of the male parent selection. 
     Plants of the new  Petunia  can also be compared to plants of the  Petunia  ‘Sunsurfcoparu’, disclosed in U.S. Plant Pat. No. 18,141. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new  Petunia  and ‘Sunsurfcoparu’ differed primarily in the following characteristics:
         1. Plants of the new  Petunia  had shorter internodes than plants of ‘Sunsurfcoparu’.   2. Plants of the new  Petunia  had smaller leaves with shorter petioles than plants of ‘Sunsurfcoparu’.   3. Plants of the new  Petunia  and ‘Sunsurfcoparu’ differed in flower color as plants of ‘Sunsurfcoparu’ had red purple-colored flowers.       

    
    
     
       BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
       The accompanying colored photographs illustrate 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 photographs 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 at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunsurfpitora’ grown in a container. 
       The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sunsurfpitora’. 
     
    
    
     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and early summer in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under commercial practices typical for  Petunia  production. During the production of the plants, day temperatures averaged 23° C. and night temperatures averaged 13° C. Plants were four months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
