Title: Calibrachoa plant named ‘INCALTRSUN’

Description:
Botanical designation:  Calibrachoa  sp. 
     Cultivar denomination: ‘INCALTRSUN’. 
     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 ‘INCALTRSUN’. 
     The new  Calibrachoa  plant is a product of a planned breeding program conducted by the Inventor in Heidesheim, Germany. The objective of the breeding program is to create new uniform, vigorous, freely-branching and early-flowering  Calibrachoa  plants with large attractive flowers and good garden performance. 
     The new  Calibrachoa  plant originated from a cross-pollination conducted by the Inventor in Heidesheim, Germany in December, 2013 of a proprietary selection of  Calibrachoa  sp. identified as code number Ca12-3602-64, not patented, as the female, or seed, parent with a proprietary selection of  Calibrachoa  sp. identified as code number Ca12-3606-90, not patented, as the male, or pollen, parent. The new  Calibrachoa  plant was discovered and first selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Heidesheim, Germany in June, 2014. 
     Asexual reproduction of the new  Calibrachoa  plant by vegetative terminal cuttings in a controlled greenhouse environment in Heidesheim, Germany since June, 2014 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 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 ‘INCALTRSUN’. These characteristics in combination distinguish ‘INCALTRSUN’ as a new and distinct  Calibrachoa  plant:
         1. Upright to outwardly spreading and low mounding to eventually trailing plant habit.   2. Vigorous growth habit.   3. Freely branching habit; dense and bushy appearance.   4. Early and freely flowering habit.   5. Large pale yellow-colored petals with cherry red-colored stripes, streaks and flecks.   6. Good garden performance.       

     The new  Calibrachoa  plant 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  have darker green-colored leaves than plants of the female parent selection.   2. Plants of the new  Calibrachoa  have larger flowers than 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 pink-colored flowers.       

     The new  Calibrachoa  plant 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 not as compact as plants of the male parent selection.   2. Plants of the new  Calibrachoa  are more freely flowering than plants of the male parent selection.   3. Plants of the new  Calibrachoa  have larger flowers than plants of the male parent selection.   4. Plants of the new  Calibrachoa  and the male parent selection differ in flower color as plants of the male parent selection have cherry red-colored flowers.       

     Plants of the new  Calibrachoa  can be compared to plants of the  Calibrachoa  sp. ‘USCAL88203’, disclosed in U.S. Plant Pat. No. 23,229. In side-by-side comparisons, plants of the new  Calibrachoa  differ primarily from plants of ‘USCAL88203’ in the following characteristics:
         1. Plants of the new  Calibrachoa  have larger flowers than plants of ‘USCAL88203’.   2. Flowers of plants of the new  Calibrachoa  have a more stable color pattern than flowers of plants of ‘USCAL88203’.   3. Plants of the new  Calibrachoa  and ‘USCAL88203’ differ in flower color as plants of ‘USCAL88203’ have yellow orange-colored flowers with random red-colored flecks and streaks.       

     Plants of the new  Calibrachoa  can also be compared to plants of the  Calibrachoa  sp. ‘USCALI413-4’, disclosed in U.S. Plant Pat. No. 19,493. In side-by-side comparisons, plants of the new  Calibrachoa  differ primarily from plants of ‘USCALI413-4’ in the following characteristics:
         1. Plants of the new  Calibrachoa  are more vigorous and denser than plants of ‘USCALI413-4’.   2. Plants of the new  Calibrachoa  have larger flowers than plants of ‘USCALI413-4’.   3. Plants of the new  Calibrachoa  and ‘USCALI413-4’ differ in flower color as plants of ‘USCALI413-4’ have yellow-colored flowers with red-colored centers and venation.

     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photographs and following observations and measurements describe plants grown during the late winter in 10-cm containers in an acrylic-covered greenhouse in Carleton, Mich. and under cultural practices typical of commercial  Calibrachoa  production. During the production of the plants, day and night temperatures ranged from 18° C. to 30° C. and light levels averaged 1,500 foot-candles. Plants were seven weeks from planting rooted cuttings when the photographs and description were taken.
