摘要：

果梅(Prunus mume Sieb. et Zucc.)原产于中国，为蔷薇科典型的配子体自交不亲和(GSI)品种。GSI至少由S位点的花柱S(S-RNase)基因和花粉S(SFB/SLF)基因决定。主要介绍了果梅GSI决定基因S基因和SFB/SLF基因的研究现状，并对基因型的鉴定技术AS-PCR的理论基础进行了介绍，对目前国内外已经鉴定出基因型的果梅品种进行了总结，这些将对果梅品种授粉树的合理配置和杂交育种的亲本选择具有重要的意义。

Abstract:

Japanese apricot (Prunus mume Sieb. et Zucc.) originates in China and it is a fruit crop with a typical of gametophytic self-incompatibility (GSI). Previous studies have shown that GSI is controlled by S locus, which consists of a pistil determinant S-ribonuclease gene (S-RNase gene) and a pollen determinant gene (SFB/SLF gene). This paper mainly introduced the recent research advances of self-incompatibility genes (S genes and SFB/SLF genes) and AS-PCR theoretical basis for identifying the genotypes in Japanese apricot, and the main S-genotypes and SFB/SLF genotypes at home and abroad of Japanese apricot were summarized, which would be valuable for selecting appropriate pollinated varieties and incompatibility parents for hybridization breeding.
