| 摘 要： | Abstract-Based on the research of juvenile (2, 3, 4 months) growth and survival of three popu-lations of two different geographic areas in Chlamys farreri from Russian and China and their F_1 hybridsderived from Chinese cultural population (CC)×Russian population (RW), Chinese wild popu-lation (CW)×Russian population (RW), Russian population (RW)×Chinese wild popula-tion (CW), the study of the medium-term (6, 8, 10, 12 months) growth and development ofChlamys farreri was carried out. The four determined results indicated that there existed different ex-tent heterosis (3%～52%) for the growth in three types of F_1 hybrids, and the offspring derived fromCC×R had a stronger heterosis among the crosses at the medium-term; the uptrend among traitsare wet weight>shell width>shell length>shell height, Chinese cultural population could be recog-nized as excellent parent, and seasonal variations influence very much on the daily increment and growthrate of each trait of Chlamys farreri and it is only able to

| Abstract: | Based on the research of juvenile (2, 3, 4 months) growth and survival of three populations of two different geographic areas in Chlamys farreri from Russian and China and their F1 hybrids Chlamys farreri was carried out. The four determined results indicated that there existed different extent heterosis (3% ～52% ) for the growth in three types of F1 hybrids, and the offspring derived from are wet weight ＞ shell width ＞ shell length ＞ shell height, Chinese cultural population could be recognized as excellent parent, and seasonal variations influence very much on the daily increment and growth rate of each trait of Chlamys farreri and it is only able to survive and could barely grow in winter (6～8 months), but grows fast in temperate season (10～12 months). |
