摘　　要：采用不同颜色荧光标记方法对罗氏沼虾Macrobrachium rosenbergii选育新品种──"南太湖2号"与非选育群体的生长性能进行了比较,试验共进行103 d。结果表明:"南太湖2号"两个选育群体间的生长性能及相对成活率差异不显著(P>0.05);"南太湖2号"选育群体的特定生长率、肥满度和肌肉中RNA/DNA值(3.86%/d、3.08、2.98)均显著高于非选育群体(3.55%/d、2.51、1.58)(P<0.05);选育群体的相对增重率比非选育群体快36.87%;选育群体的相对成活率比非选育群提高7.76%。研究表明,应用数量遗传学方法选育的罗氏沼虾"南太湖2号"的生长性能要明显优于非选育群体。A comparative study of the growth performance was carried out between the new selected strain of giant freshwater prawn Macrobrachium rosenbergii,＂South Tailake No.2＂ and the non-selected population tagged with a unique family code by injection of ＂Visible Implant Fluorescent Elastomers＂（VIE） with different colours.The results showed that there were no significant differences in growth performance and relative survival rate between the two population of the new selected strain of ＂South Tailake No.2＂（P0.05）.The ＂South Tailake No.2＂had significantly（P0.05） higher specific growth rate（3.86 %/d）,condition factor（3.08）and RNA/DNA ratio（2.98） than the non-selected population（3.55 %/d,2.51 and 1.58） did.There were 36.87% higher relative growth rate and 7.76% higher relative survival rate in ＂South Tailake No.2＂ population than those in the non-selected population.The results indicate that the growth performance of ＂South Tailake No.2＂ selected by quantitative genetics means are better than non-selected population.
