在以前初步研究的基础下,继续对五类的65个小麦品种用小麦叶锈菌同一小种的9个菌株进行接种,获得的侵染型资料按照生物间遗传学的原理和方法作遗传分析。结果表明;在供试的小麦品种和叶锈菌株对病害反应的相互作用中,有25个品种与9个菌株具1～3相应基因对;7个品种与9个菌株有4～6基因对;17个品种与9个菌株具7～9基因对;16个品种与9个菌株不存在抗病基因对。据此结果,讨论认为可以适当地利用带有较多抗病基因的品种,安排大田种植,或作为抗源材料进行小麦抗叶锈品种的选育。
Based on the previous preliminary studies, we continued to inoculate 9 wheat strains of 65 wheat cultivars in five categories with the same race of Puccinia triticina. The obtained invasive materials were subjected to genetic analysis according to the principles and methods of intergeneric genetics . The results showed that among the tested wheat varieties and leaf rust strains, there were 25 genera and 9 strains with 1 ~ 3 corresponding gene pairs, 4 varieties with 7 genes and 9 strains with 4 ~ 6 genes Seventeen varieties and nine strains had 7-9 pairs of genes, and 16 varieties and nine strains did not have resistance gene pairs. Based on these results, the discussion concluded that it is possible to use cultivars with more disease-resistance genes, arrange field planting, or select anti-leaf rust resistant wheat varieties as anti-source materials.
