Title: Calibrachoa plant named ‘Sunbel 205’

Description:
Botanical designation:  Calibrachoa  sp. 
     Cultivar denomination: ‘SUNBEL 205’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Calibrachoa  plant, botanically known as  Calibrachoa  sp. and hereinafter referred to by the name ‘Sunbel 205’. 
     The new  Calibrachoa  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 develop new compact, mounding and freely branching  Calibrachoa  plants with numerous large and attractively colored flowers. 
     The new  Calibrachoa  plant originated from a cross-pollination conducted by the Inventors in Higashiomi, Shiga, Japan in September, 2009 of a proprietary selection of  Calibrachoa  sp. identified as code number T641-2, not patented, as the female, or seed, parent with a proprietary selection of  Calibrachoa  sp. identified as code number 8571-203, not patented, as the male, or pollen, parent. The new  Calibrachoa  plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in July, 2010. 
     Asexual reproduction of the new  Calibrachoa  plant by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since July, 2010 has shown that the unique features of this new  Calibrachoa  plant are stable and reproduced true to type in successive generations. 
     SUMMARY OF THE INVENTION 
     Plants of the new  Calibrachoa  have not been observed under all possible 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 ‘Sunbel 205’. These characteristics in combination distinguish ‘Sunbel 205’ as a new and distinct  Calibrachoa  plant:
         1. Compact and mounding plant habit.   2. Vigorous growth habit.   3. Freely branching habit.   4. Freely flowering habit.   5. Long flowering period.   6. Relatively large light yellow-colored flowers.   7. Good garden performance.       

     Plants of the new  Calibrachoa  can be compared to plants of the female parent selection. Plants of the new  Calibrachoa  differ primarily from plants of the female parent selection in the following characteristics:
         1. Plants of the new  Calibrachoa  are more compact than plants of the female parent selection.   2. Plants of the new  Calibrachoa  are more mounding than and not as upright as plants of the female parent selection.   3. Plants of the new  Calibrachoa  and the female parent selection differ in flower color as plants of the female parent selection have light orange-colored flowers.       

     Plants of the new  Calibrachoa  can be compared to plants of the male parent selection. Plants of the new  Calibrachoa  differ primarily from plants of the male parent selection in the following characteristics:
         1. Plants of the new  Calibrachoa  are more compact than plants of the male parent selection.   2. Plants of the new  Calibrachoa  are more mounding than and not as decumbent as plants of the male parent selection.   3. Plants of the new  Calibrachoa  and the male parent selection differ in flower color as plants of the male parent selection have darker yellow-colored flowers.       

     Plants of the new  Calibrachoa  can also be compared to plants of  Calibrachoa  ‘Sunbelki’, disclosed in U.S. Plant Pat. No. 11,558. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new  Calibrachoa  and ‘Sunbelki’ differed primarily in the following characteristics:
         1. Plants of the new  Calibrachoa  were more compact than plants of ‘Sunbelki’.   2. Plants of the new  Calibrachoa  were more mounding than and not as decumbent as plants of ‘Sunbelki’.   3. Plants of the new  Calibrachoa  had shorter internodes than plants of ‘Sunbelki’.   4. Plants of the new  Calibrachoa  had smaller leaves than plants of ‘Sunbelki’.   5. Plants of the new  Calibrachoa  and ‘Sunbelki’ differed slightly in flower color.

     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial  Calibrachoa  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 the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
