苹果自交不亲和基因型(S基因)研究进展

摘要

Apple (Malus domestica Borkh.) is a typical species in Rosaceae family that exhibits gametophytic self-incompatibility (GSI).In this paper, the research advance in the S-alleles (more than 30 S-genes) of apple was reviewed,PCR-based theoretical basis and methods for identifying the S-genotypes of apples were summarized, more than 500 S-genotypes of apples which were identified with various methods were enumerated, which would be valuable for selecting appropriate pollinated varieties and incompatibility parents for hybridization breeding.%苹果是蔷薇科一个典型的配子体自交不亲和果树树种.本文详细介绍了苹果S等位基因研究现状,系统介绍了基于PCR技术的苹果S基因型鉴定的理论基础和主要方法,列出了迄今国内外应用这些方法鉴定出的500多个苹果品种的S基因型.本文对于苹果品种授粉树的合理配置和杂交育种亲和性亲本选择具有重要的指导意义.
