188份小麦品种(系)抗条锈病研究OA
Study on Stripe Rust Resistance of 188 Wheat Varieties(Lines)
新疆是中国小麦条锈病的独立流行区,近年来该病害持续加重,严重威胁粮食安全生产.为了解新疆小麦抗条锈病基因分布及优异抗性基因型,分析了 188份在伊犁河谷种植的小麦品种(系)对当前条锈菌优势小种(CYR32、CYR33、CYR34)与水源、贵农致病类群的混合菌的抗性,同时利用分子标记检测了 Yr5、Yr10、Yr15、Yr17、Yr18、Yr26、Yr29、Yr30、Yr52、Yr65、Yr75、Yr78、Yr80、Yr82和Yr86共 15 个抗条锈病基因的分布.结果表明,在188份小麦品种(系)中,对混合条锈菌的抗性连续两年达到中抗及以上水平的材料共106份,占比56.4％,其中11份为高抗材料,说明参试材料整体条锈病抗性水平较高.经分子标记检测,携带Yr5、Yr10、Yr15、Yr17、Yr18、Yr26、Yr29、Yr30、Yr52、Yr65、Yr75、Yr78、Yr82和Yr86 抗性基因的材料数分别为84(44.7％)、149(79.3％)、19(10.1％)、106(56.4％)、185(98.4％)、181(96.3％)、172(91.5％)、76(40.4％)、147(78.2％)、107(56.9％)、26(13.8％)、60(31.9％)、127(67.6％)和13(6.9％)份;其中,聚合 3 至 12 个抗性基因的材料数量分别为1(0.5％)、3(1.6％)、13(6.9％)、21(11.2％)、34(18.1％)、58(30.9％)、34(18.1％)、16(8.5％)、5(2.7％)和2(1.1％)份;在所有供试材料中均未检出Yr80基因.综上所述,188份小麦品种(系)具有较高的抗条锈病水平,筛选出的106份抗性材料可作为小麦条锈病抗性育种的种质.
Xinjiang is an independent epidemic region for wheat stripe rust in China.In recent years,the disease has shown a persistent and aggravated trend,posing a serious threat to grain production security.To investigate the distribution of stripe rust resistance genes and identify elite resistant gen-otypes in Xinjiang wheat germplasm resources,188 wheat varieties(lines)cultivated in the Ili River Valley were evaluated for their resistance to the current predominant Puccinia striiformis f.sp.triti-ci physiological races(CYR32,CYR33,CYR34)and mixed inocula of Shuiyuan and Guinong patho-genic groups.Moreover,molecular detection was performed using 15 closely linked molecular mark-ers for the following stripe rust resistance genes:Yr5,Yr10,Yr15,Yr1 7,Yr18,Yr26,Yr29,Yr30,Yr52,Yr65,Yr75,Yr78,Yr80,Yr82,and Yr86.The results revealed that,among the 188 wheat varieties(lines),106 accessions(56.4％)exhibited moderate resistance or higher levels of resistance o-ver two consecutive years,including 11 highly resistant accessions,indicating a generally high level of resistance in the tested materials.Molecular marker analysis showed that the numbers of accessions carrying the resistance genes Yr5,Yr10,Yr15,Yr17,Yr18,Yr26,Yr29,Yr30,Yr52,Yr65,Yr75,Yr78,Yr82,and Yr86 were 84(44.7％),149(79.3％),19(10.1％),106(56.4％),185(98.4％),181(96.3％),172(91.5％),76(40.4％),147(78.2％),107(56.9％),26(13.8％),60(31.9％),127(67.6％),and 13(6.9％),respectively.Among them,the number of materials that aggregated 3 to 12 resistence genes were 1(0.5％),3(1.6％),13(6.9％),21(11.2％),34(18.1％),58(30.9％),34(18.1％),16(8.5％),5(2.7％)and 2(1.1％)respectively.The Yr80 gene was not detected in any of the tested materials.In summary,188 wheat varieties(lines)exhibited a high level of resistance to stripe rust.The 106 resistant germplasms screened can serve as resistance sources for breeding wheat resistant to stripe rust.
