188份小麦品种(系)抗条锈病研究
Study on Stripe Rust Resistance of 188 Wheat Varieties(Lines)
摘要
Abstract
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.关键词
