Floricultural plant breeding is necessary to select simultaneously several superior traits. Therefore, the improvement for specific trait of ornamental plant is required both time and cost. Because flower color was important as a breeding objective, we analyzed floral anthocyanin biosynthesis genes using commercial petunias, which were one of model plant of floral color gene, and developed PCR based marker. In this study, the biosynthesis mechanism of white and yellow color in the corolla was analyzed to develop gene marker for white and yellow flower color selection.
