摘　　要：基因流是影响植物种群的遗传组成和遗传结构的重要因子。父本分析通过直接估算基因流,对了解群体间或世代间的基因流动及性选择适合度有重要的理论意义,生产上可以指导林木种子园的设计和遗传管理。本文介绍了林木群体基因流及父本分析的研究进展,以油松种子园为例讨论了用同工酶标记进行父本分析的优缺点并论述了利用分子标记进行父本分析的优势。Gene flow is an important factor influencing the genetic structure of plant populations. Paternity analysis can be used to measure gene flow directly, it could provided the foundation for understanding the degree of gene flow among populations or generations and the sexual selection fitness, for guidance to the designation and management for seed orchard . The advances of gene flow and paternity analysis in forest population recent years were reviewed, and the limitation of paternity analysis making use of enzyme marker in a seed orchard was discussed.
