Title: Calibrachoa plant named ‘USCAL09301’

Description:
Botanical designation:  Calibrachoa  sp. 
     Cultivar denomination: ‘USCAL09301’. 
     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 ‘USCAL09301’. 
     The new  Calibrachoa  plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan and Bonsall, Calif. The objective of the breeding program is to create new uniform and freely-branching  Calibrachoa  plants with unique and attractive flower coloration and good garden performance. 
     The new  Calibrachoa  plant originated from a cross-pollination made by the Inventor on May 8, 2010 in Higashiomi, Shiga, Japan of a proprietary seedling selection of  Calibrachoa  sp. identified as code name 10CJ04-03, not patented, as the female, or seed, parent with a proprietary seedling selection of  Calibrachoa  sp. identified as code name 10CJ70-02, not patented, as the male, or pollen, parent. The new  Calibrachoa  plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Bonsall, Calif. on May 13, 2011. 
     Asexual reproduction of the new  Calibrachoa  plant by terminal cuttings in a controlled environment in Bonsall, Calif. since May 14, 2011 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 various 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 ‘USCAL09301’. These characteristics in combination distinguish ‘USCAL09301’ as a new and distinct  Calibrachoa  plant:
         1. Upright, outwardly spreading to trailing and mounding plant habit.   2. Freely branching habit; dense and bushy appearance.   3. Early and freely flowering habit.   4. Pale golden yellow-colored flowers with dark rusty red-colored venation and eye.   5. 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  are more mounding than and not as creeping as plants of the female parent selection.   2. Plants of the new  Calibrachoa  and the female parent selection differ in flower color.       

     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 more mounding than and not as upright as plants of the male parent selection.   2. Plants of the new  Calibrachoa  and the male parent selection differ in flower color.       

     Plants of the new  Calibrachoa  can be compared to plants of the  Calibrachoa  sp. ‘USCALI411-7’, disclosed in U.S. Plant Pat. No. 19,492. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new  Calibrachoa  differed primarily from plants of ‘USCALI411-7’ in flower color as plants of ‘USCALI411-7’ had orange-colored flowers. 
     Plants of the new  Calibrachoa  can be compared to plants of the  Calibrachoa  sp. ‘USCALI413-8’, disclosed in U.S. Plant Pat. No. 19,843. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new  Calibrachoa  differed primarily from plants of ‘USCALI413-8’ in flower color as plants of ‘USCALI413-8’ had orange-colored flowers with red-colored centers.

     DETAILED BOTANICAL DESCRIPTION 
     The aforementioned photographs and following observations, measurements and values describe plants grown during the late autumn in one-gallon containers in a polyethylene-covered greenhouse in Bonsall, Calif.
