213份燕麦种质的白粉病抗性评价
Powdery mildew resistance evaluation of 213 oat germplasm resistance to powdery mildew
摘要
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.关键词
