In order to explore the heredity of leaf veins of Cyclamen Hederifolium and to breed excellent varieties,selfing measurement for six types of different leaf veins were carried out and the genetic constitutions of leaf veins were studied according to the separation conditions of their progenies. The results showed that the inbred progenies of B or M types were B or M types with a percentage of 100% while the progenies of F,H,X and L types had character segregations. The separation law illustrated that leaf veins of Cyclamen Hederifolium were controlled by minor multiple genes and each locus was consisted of a pair of alleles,RLof RB. RL was responsible for the green phenotype of leaves and RBwas responsible for the silvery white phenotype of leaves. Leaves were deep green when the genotype of the locus was RLRL; leaves were green when the genotype was RLRB; leaves were silvery white when the genotype was RBRB. The aggregative pattern of each locus formed different leaf vein types. The gene control modes of leaf vein variations were the basis for the breeding of excellent varieties of Cyclamen Hederifolium.
