To identify the theoretic foundation for maintaining and improving high quality varieties and breeding new Fl hybrids, flower color segregation occurred in the offspring in both serf-pollination and cross-pollination of varieties of different colors were investigated. The main results indicate that the heredity of Cyclamen persicum color follows both quantitative and qualitative hereditary regularity. All genes can be classified as two groups of the throat-gene and coronal-gene occupying different spots on the chromosome. The colored gene is the dominant gene, while the white gene is (Jie recessive one. The gene groups and their quantity determine the color of cyclamen persicum. And sometimes the throat- gene and the coronal-gene take a recombination, forming a new type of flower.
