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%。
Chronic rust resistance is important for maintaining disease resistance stability and durability. 10 representative winter wheat cultivars were selected from 2003 to 2004 and studied on the chronic rust in Qingshui County. The results showed that Lepidaria, Stouplli and Wudu white cocoons were highly slow-rusting varieties; Qingnong 3 and Xianong 4 were moderately slow-rusting cultivars; Lantian 1 and Qingnong 1 were Low-speed slow-rusting varieties; natural selection of 15 and 63 for the rust-fast varieties. The characteristics of disease resistance of slow-rusting cultivars are as follows: the latent period is long, the reaction type is susceptible, the prevalence is less than 50% or the severity is less than 25%, the disease index is less than 15% or the final disease index is less than 60% The rate is less than 9% or the relative grain weight loss rate is less than 40%.
