摘　　要：本实验通过克隆测序S基因,鉴定了14个新疆与中亚梨品种的S基因型,为‘库尔勒香梨’授粉树的筛选提供了理论依据。经鉴定发现,‘麻梨’的S基因型为S16Se、‘库车阿木特’为S28S19、‘大果奎克阿木特’为S28S19、‘塔西阿木特’为S28S19、‘比凯2号’为ShS4、‘比凯3号’为S44S37、‘比凯4号’为S22Sd、‘比凯5号’为ShSe、‘比凯10号’为S4S37、‘比凯12号’为S22Se、‘卡杜斯可孜莫若’为ShSe、‘伊塞3号’为S22Se、‘伊塞1号’为SiSe、‘林中美人’为SdSe。其中,‘库车阿木特’、‘塔西阿木特’和‘大果奎克阿木特’含有与‘库尔勒香梨’相同的S28;‘比凯4号’、‘比凯12号’和‘伊塞3号’含有与‘库尔勒香梨’相同的S22。因此,上述6个品种不宜作为‘库尔勒香梨’的授粉树。本研究结果不仅为‘库尔勒香梨’授粉树的筛选提供了理论依据,也丰富了中国梨资源的S基因信息。In this research,we identif ied S-genotypes of fourteen Xinjiang and Central Asia pear cultivars by clone and sequencing S-gene to provide theoretical basis for selection of pollination varieties of'Korla fragrant pear'.According to the results,the S-genotypes of the fourteen pear cultivars are as below.'Mali'S16Se,'Kucheamute'S28S19,'Daguokuikeamute'S28S19,'Taxiamute'S28S19,'Bikai No.2'ShS4,'Bikai No.3'S44S37,'Bikai No.4'S22Sd,'Bikai No.5'ShSe,'Bikai No.10'S4S37,'Bikai No.12'S22Se,'Kadusikezimoruo'ShSe,'Yisai No.3'S22Se,'YisaiNo.1'SiSe,'Linzhongmeiren'SdSe.Amongthe fourteen pear cultivars,'Kucheamute','Taxiamute','Daguokuikeamute','Bikai No.4','Bikai No.12'and'Yisai No.3'contains the same S gene as'Korla fragrant pear',so the six cultivars are not suitable for pollination of'Korla fragrant pear'.The results of the research provided a theoretical basis for the selection of pollination trees of'Korla fragrant pear',and enriched the S-gene information of pear cultivars in China.
