以珠江群体斑鳢为母本,分别与钱塘江群体、微山湖群体、洞庭湖群体、鄱阳湖群体乌鳢为父本进行杂交,在繁殖性能及杂交F1生长和形态方面进行比较分析。结果表明,繁殖性能上各杂交组合间的差异主要表现在催产率方面,斑鳢与洞庭湖群体乌鳢组合催产率最高,斑鳢与微山湖群体乌鳢组合及斑鳢与鄱阳湖群体乌鳢组合催产率较低;在F1生长方面,斑鳢与微山湖群体乌鳢群体组合优势显著,而斑鳢与钱塘江群体乌鳢组合、斑鳢与洞庭湖群体乌鳢组合、斑鳢与鄱阳湖群体乌鳢组合间差异不显著。 The populations of Cantonie macularua from the Pearl River Group were used as the female parent for the crosses with Qiantang River, Weishan Lake, Dongting Lake and Poyang Lake as the male parent, and their reproductive performance and F1 growth and morphology were compared. The results showed that the differences in reproductive performance among the hybrid combinations mainly manifested in the rate of oxytocin, cantharidin and Dongting Lake group Wuhu combination of oxytocin rate was the highest, macular cluster and Weishanhu population Wuhu combination and cantharidin and Poyang Lake group Wuhu combination oxytocin In the aspect of F1 growth, there was a significant advantage in the combination of macrophylla and Weishanhu population, while the combination of macrophylla with Qiantang River population, the combination of macrophylla and Dongting Lake population, the combination of macrophylla and Poyang Lake population, The difference was not significant.
