摘要： 以埃及品系尼罗罗非鱼家系的雌鱼作为母本,美国品系奥利亚罗非鱼家系的雄鱼作为父本进行杂交配对。通过耐寒与生长性能评价及低温选育,筛选获得亲本后,以巢式配对的方法(雌雄比例3∶1)配对尼奥罗非鱼杂交家系,获得F1代家系36个。耐寒和生长性能结果表明,F1代31个尼奥家系平均半致死温度为7.45 °C,比自然种群降低8.81％,平均相对存活率提高17.6％,平均生长速度提高13.2％。获得综合性能优秀的F1代耐寒型尼奥罗非鱼杂交配套系组合2个(F1CT0401、F1CT0203),其平均半致死温度分别为7.02和7.24 °C,低温死亡率分别为40.50％和49.5％,比自然种群杂交尼奥罗非鱼降低17.4％和11.35％,相对死亡率降低30.0％和26.9％,产量分别提高12.9％和38.7％。示范养殖F1代耐寒型尼奥罗非鱼成活率为(84.39±6.65)%,平均产量(1 220.20±94.77) kg/667 m2,平均规格(723.0±101.2) g;与对照组相比,示范池塘的耐寒型尼奥罗非鱼越冬死亡率降低了19.11%(P＜0.05),平均每667 m2产量提高了36.59%(P＜0.05)。耐寒和生长性能比自然种群有了大幅提高。

Abstract: To study the cold tolerance and growth performance ofO.mossambicus×O.niloticus hybrid lines,low-temperature stress test and growth comparison test were used to select the excellent pedigree of cold-tolerant Egyptian strainof Nile tilapia (female) and the America strains of Blue tilapia (male).Through the cold tolerance and growth performance evaluation and the low temperature breeding,breeding,parents Nile and Blue tilapia were obtained to crossbreeding.36 of F1 generation O.mossambicus×O.niloticus hybrid families were mated through nested paired method (the proportion of male and female was 3∶1).The results showed that,the mean Semi-lethal temperature of 31 families of O.mossambicus×O.niloticus hybrid F1 generation was 7.45 °C,and 8.81% lower thanin natural populations,the average relative survival rate and average growth speed increased by 17.6% and 13.2%,respectively.2 excellent F1 generation of crossbreeding combination (F1CT0401,F1CT0203) were obtained,and the mean Semi-lethaltemperature were by 7.02 °C and 7.24 °C,low mortality rates were 40.5% and 49.5%,respectively,which decreased 17.4% and 11.35% than in natural populationsof O.mossambicus×O.niloticus hybrid,the relative mortality decreased by30% and 26.9%,yield increased by 12.9% and 38.7% respectively.The survival rate was(84.39±6.65)% of farming demonstrated F1 generation cold tolerant O.mossambicus×O.niloticus hybrid,and the average produce was (1 220.20±94.77) (kg·667 m-2),the average size was (723.0±101.2) g.Compared with the control group,the overwintering mortality decreased by 19.11% (P＜0.05)and the average yield increased by 36.59% (P＜0.05).Thecold tolerance and growth properties of F1 O.mossambicus×O.niloticus hybrid had been greatly improved than the natural populations.

Key words: O.mossambicus×O.niloticus, crossbreeding system, cold tolerance, growth performance, selection and breeding
