| 摘 要： | 为明确不同燕麦种质资源抗白粉病差异,于2012-2014年采用田间自然感病法对213份燕麦(Avena sativa)种质进行了由禾布氏白粉菌燕麦专化型(Blumeria graminis f.sp.avenae)引起的燕麦白粉病的田间抗性筛选和评价。结果表明,在供试材料中未监测到免疫材料;12份材料青永久420、青永久316、青永久9、青永久252、青永久98、青永久180、青永久479、青永久25、青永久87、永118、青永久304和五燕6号表现高抗(HR);199、青永久164、青永久237、青永久260、青永久83、青永久49、青永久016、青永久94、青321、青永久154、原45、永73-1、83-27、S20-36-6、保罗、330、原15和白苏鲁2055共18份材料表现中抗;其余183份表现中感、高感和极感,分别占供试材料的5.6%、8.5%和85.9%。获得的这些有效抗病种质,可为品种的合理布局及抗病育种提供核心抗源。

| Abstract: | In order to confirm the difference of oat germplasm resistance to Blumeria graminis f.sp.avenae, the resistance of 213 oat germplasm to this pathogen were evaluated using the method of naturally infected under field conditions from 2012 to 2014.The results showed that there was no immune material.Twelve materials were high resistance, including Qingyongjiu 420, Qingyongjiu 316, Qingyongjiu 9, Qingyongjiu 252, Qingyongjiu 98, Qingyongjiu 180, Qingyongjiu 479, Qingyongjiu 25, Qingyongjiu 87, Yong 118, Qingyongjiu 304 and Wuyan No.6.Eighteen materials were middle resistance, for example, 199, Qingyongjiu 164, Qingyongjiu 237, Qingyongjiu 260, Qingyongjiu 83, Qingyongjiu 49, Qingyongjiu 016, Qingyongjiu 94, Qing 321, Qingyongjiu 154, Yuan 45, Yong 73-1, 83-27, S20-36-6, Paul, 330, Yuan 15 and Baisulu 2055.There were 5.6%, 8.5% and 85.9% of the left 183 materials were middle susceptible, high susceptible and extremely high susceptible, respectively.These evaluation can provide core resource for disease resistance breeding and varieties reasonable distribution. |
