Flower color of hairy vetch (Vicia villosa Roth) was observed individually in F2 of crosses among violet, white, pink flower varieties, and between pale pink and pink flower varieties for providing information of useful gene as source of colored flower. F2 segregation mode of flower color between cross of white/violet was fitted to 3 violet : 1 white, and same segregation ratio of 3 violet : 1 pink was found in F2 of cross of violet/pink flower variety. Also, F2 segregation of flower color between cross of pale pink/pink flower variety was fitted to 3 violet : 1 white. When white flower was crossed with pink flower, flower color in F2 population segregated into 9 violet : 3 pink : 4 white. Based on the results, this study indicated that flower color of parental varieties was controlled by recessive epistatic interactions of two genes, and pale pink flower color was recessive to the pink color of the parental variety. This flower color inheritance may be used for practical application in breeding of hairy vetch variety
