%X Diallel cross method was used to study the inheritance of 3 shell colors (orange, brown and purple-brown) in Chlamys nobilis. The results showed that the shell colors of offspring for crosses orange ♂× brown ♀ and orange ♂× purple-brown ♀ were all orange; in the offspring from crosses brown ♂× orange ♀ and purple-brown ♂× orange ♀, separation ratio of the shell color were orange : brown = 1 : 1 and orange : purple-brown = 3 : 1 respectively, indicating that orange shell color was dominant over brown and purple-brown shell color, and no maternal inheritance occurred. In the two families from cross orange ♂× orange ♀, offspring of one family were all orange shell color, and for the offspring of the other family color separation ratio approximately orange : brown = 3 : 1. This showed that in the first family one parent was dominant homozygous, while in the other family two parents were all heterozygous. In the two families from crosses brown ♂× brown ♀ and purple-brown ♂× purple-brown ♀, the offspring all had the same shell color as their respective parents, indicating all parents with brown shell or purple-brown shell were recessive homogeneous. The fact that shell color of offspring for each family set up in the experiment had the same color as their parents suggested that the shell color was qualitative character. Selection of shell color was effective for the scallop.
