摘要
慢条锈性对于保持抗病稳定性和持久性具有重要意义。2003～2004年选用10个具有代表性的当地主栽冬小麦品种,在清水县进行慢条锈性研究。结果表明:里勃留拉、斯汤佩利和武都白茧为高度慢锈性品种;清农3号和咸农4号为中度慢锈性品种;兰天1号和清农1号为低度慢锈性品种;天选15和幅63为快锈性品种。慢锈性品种的抗病特点为潜育期长,反应型表现感病,普遍率低于50%或严重度低于25%,病情指数小于15%或终期病情指数小于60%,千粒重损失率低于9%或相对千粒重损失率低于40%。
Slow strip-rust is important to keep stable and sustained disease resistance. Between 2003 and 2004, ten cultivars in Qingshui were selected to test the characteristics of slow strip-rust. The results showed that Libellula, Strampelli and Wudubaijian were highly slow rust cultivars; Qingnong No.3 and Xiannong No.4 were middle slow rust cultivars; Lantian No.1 and Qingnong No.1 were low slow rust cultivars; Tianxuan 15 and Fu 63 were fast rust cultivars. Conclusions had been drawed that slow-rust cultivars had long latent period, prevalence rate was lower than 50 % or severity was lower than 25 %, disease index was lower than 15 % or final disease index was lower than 60 %, damage rate of kernel weight was lower than 9 % or relative damage rate of kernel weight was lower than 40 %.
