山西省小麦品种与不同生态区叶锈菌相互作用的研究

The Study on the Interaction of Wheat Cultivars and Isolates of Leaf Rust Collected from Different Ecological Regions of Shanxi Province

1991年在河北农业大学温室用1989年从山西省南部中熟冬麦区、中部晚熟冬麦区、北部春麦区的13个县(市)的不同生态区采集的181个叶锈菌菌株与山西省的33个生产品种、后备品种及亲本材料研究二者之间的相互作用.结果表明,不同生态区叶锈菌群体具有不同的毒性.例如丰抗13在各生态区表现的抗、感反应不一致,即使在表现抗病的地区,其抗性也不一致.

The interaction between the, 181 isolates of leaf rust collected from different ecological regions of Shanxi Province in 1989 and the 33 wheat commercial, candidate cultivars as well as parental materials from the Province were studied in the greenhouse of Hebei Agricultural University by the Department of Plant Protection in 1991, under the cooperation with the Institute of Plant Protection, Shanxi Academy of Agricultural Sciences. The results showed that the leaf rust populations from different ecological regions did have different virulence. For example, cv. Fengkang 13 were either susceptible to or resistant against the leaf rust populations. However in the area where cv. Fengkang 13 appeared to be resistant, its resistance differed remarkably.
