摘要
分析了1983～1992年“全国小麦品种抗锈性变异观察圃”西藏点析101个参试品种的抗性变异情况,可分为:(1)始终感病,如白蚰包、丰产3号、阿夫、阿勃、早洋等;(2)由抗变感,如洛夫林10、阿芙乐尔、山前麦等;(3)保持抗性,如水源11、PKBL-16、钱保德、绵阳11、牛朱特等,是值得利用的抗源。同时分析了已知抗性基因品种、西藏主要生产品种肥麦之抗性变异情况及区域间发病差异。
The variability of resistance to stripe rust for 101 wheat and barley varieties had been observed in The Chinese national uniform wheat stripe rust nurseries on 1983-1992. The change of resistance in varieties could be classified into the following categories, 1. being susceptible since the first observed year, such as Baiyoubao, Fengchang 3, Funo, Abbond-abza, Early premium et al; 2. tossing resistance, such as Lovrin 10, Afuloer, Shanqian
et al; 3. maintaining resistance, such as Shuiyuan 11, PKBL-16, Qianbaode, Mian-yang 11, Neuzucht et al, being valuable resistance sources. The resistance change of the known resistant genotype and Tibet commercial variety, heines hyde, and the difference of disease development between regions were also analyzed.
