Three populations of two different geographic areas in Chlamys farreri from Russian and China and the Ft hybrids derived from Chinese wild population (CW)♀×Russian population (R)♂,Chinese cultural population (CC)♀×Russian population (R)♂,Russian population (R)♂Chinese wild population (CW)♂,from each group 40-50 individuals were selected for the research on the growth characteristics.The three determined results indicate that there existed different extent heterosis (or hybrid vigour) for growth of shell height, shell length, shell thickness and live weight, and that growth of hybrid in CW♀×R♂ has a stronger heterosis among the crosses at the end of send month, and no significant difference at the end of third month among the crosses, and growth of hybrid in R♀×CC♂ has a stronger heterosis among the crosses at the end of fourth month,.Russian population can be recognized as excellent parent in growth at the first 3 months and Chines culture population is better at the end of fourth month; Chines wild population has a better growth than Chinese culture population at the second month and no sienificant difference at the end of third month, and reverses at the fourth month.
