| 摘 要： | 针对中国地方猪种遗传资源保存要以活体保种为主要形式,且面临经济特性选育提高,以及品种数量多的三大特点,为突破以Wright有效含量为核心的保种理论关于避免选择等条件的限制,本文提出了变无目标的随机保种为有目标保种,变避免选择的静态保种为利用选择的动态保种,变各品种互不联系的孤立保种为特性统一分配的系统保种策略,并通过特性系统分配多目标规划数学模型,给出了中国猪种质特性的保存方案。该模型有两个目标,一是使特性安排在表现最突出的品种中保存,二是使品种选择特性之间遗传正相关大,负相关小。

| Abstract: | The pig genetic resources in china would be protected mainly in the form of living animal and its productivity should be improved. The new straitages of conserving animal genetic resources would be taking concrete genetic features as conserving objects, distributing the objects to breeds with systemic method and protecting the features by selection. The scheme of conserving pig genetic features in China is given by multi objective programming method. |
