聚类分析在制订育种方案中的应用

Cluster Analysis is Used for Making Animal Breeding Plan

提出了品种选育中通过聚类分析划分品系的新思想．对全部目标性状做聚类分析，同类者放入同一品系中选育较好，不同类者可放入同一品系或不同品系．通过聚类分析可清楚地看出目标性状间的关系，为制订育种方案提供客观、清晰的理论依据．

This paper proposes a new method on strain breeding. That is differentiating strains of a breed through cluster analysis. Make cluster analysis on all the objective traits. It is better to put the same kind of objective traits in the same strain, and different sorts of objective traits should be selected in the same strain or different strains. Through cluster analysis breeder can see the relationship among the objective traits clearly. It offers objective, clear theoretical evidence for making breeding plan.
