通过对俄罗斯和中国两个不同地理区域的栉孔扇贝幼虫期(2、3、4个月)和中期(6、8、10、12个月)生长和存活的研究，以及中国文化群体(CC)♀×俄罗斯野生群体(RW)♂和中国野生群体(CW)♀×俄罗斯野生群体F_(1)杂交体的F_(1)′生长和存活情况的研究。群体(RW)♂,对栉孔扇贝后期(12、14、16、19、21、24月)生长发育进行了研究。四项测定结果表明,F_(1)杂种和F_(1)′杂种生长均存在不同程度的杂种优势(3.16%～37.18%),前者杂种优势较强,杂交性较好。综合来看，湿重大于壳宽大于壳长大于壳高为上升趋势，中国文化群体可被认定为优良亲本，生长速度（日增量）在16月（11月）达到高峰，是栉孔扇贝收获的好时机。
On the basis of the research of juvenile(2,3,4 months) and medium-term(6,8,10,12 months) growth and survival of three populationof twodifferentgeographic areas inChlamys farrerifrom Russia and China and their F_(1)hybrids derived from Chinese cultural population(CC)♀×Russian wild population(RW)♂andF_(1)′ hybridsderived fromChinese wild population(CW)♀×Russian wild population(RW)♂,the study of the later period(12,14,16,19,21,24months)growth and development of Chlamys farreri was carried out.The fourdeterminedresults indicated that there existeddifferent extent heterosis(3.16%～37.18%) for growth in F_(1)hybrids andF_(1)′ hybrids,the former had a stronger heterosisand it was abetter cross combination,the uptrendamong traits were wetweight being greater than shell width being greater than shell length being greater than shell height,Chinese cultural population could berecognized as excellent parent,andthe growth rate(the daily increment) had reached a peak at 16months(November),it was a good time for harvestofChlamys farreri.
