摘　　要：梨是由单一位点S等位基因控制的典型配子体自交不亲和性果树,其自交授粉结实率低,品质差,需配置授粉品种。因此,对梨品种S基因及品种授粉树合理配置进行深入研究具有重要意义。有鉴于此,详细介绍了梨S等位基因的研究现状,并对迄今国内外鉴定出的500多个梨品种的S基因型进行汇总,对应用较为广泛的PCR-RFLP技术和S基因DNA序列分析法以及梨S基因芯片杂交技术进行系统介绍。Pear is a kind of fruit tree with gametophytic self-incompatibility which results in low seed setting rate and poor quality and need to select appropriate pollinate trees.This review introduced the research status of pear S allele in detail,and summarized the S genotypes of more than 500 pear varieties identified so far at home and abroad.Widely applied techniques such as PCR-RFLP,S gene DNA sequence analysis as well as pear S gene chip hybridization technology were systematically introduced.This paper will be of a great guiding significance for the further study of pear S gene and for the proper allocation of pollination trees in pear production.
