摘　　要：通过分析中国美利奴羊新疆军垦型的状态,得到了一系列参数,应用在育种方案最优化模型计算中.这些参数是:经济学及数量遗传学参数、育种过程中的生物学和育种技术参数、群体结构参效、育种成本与投资参数以及育种值估计时所使用的信息来源.借助一个特定模型计算出了预期可实现的多性状综合育种进展与各性状的遗传进展,同时计算出了预期的育种产出、育种投入以及育种效益.计算结果表明.A,B 和 C 品系有着相近的育种进展和遗传进展以及育种效益.新疆军垦型的选择标准应当统一。The existing situation for Chinese Merino sheep,type Junken in Xinjiang was described. The parameters were used to study the optimization of breeding plan.They are economic and population genetic parameters,biologic coefficients for breeding course,parameters of populament structure,breed- ing costs,parameters of investment and source of information for estimating breeding value.With deter- ministic model the expected response for monetary and natural gain as well as for breeding return,cost and profit was estimated.The results showed that merits of 3 lines were same nearly.So the selection criteria for Chinese Merino sheep type Junken should be same.
