摘　　要：为详细了解我国近几年来育成的北方春大豆品系对灰斑病的抗性表现,对来自2003～2006年200份大豆品系的灰斑病7号生理小种抗性数据进行了整理,统计分析北方春大豆整体的抗性情况和各省育成的北方春大豆品系抗性表现及年度间的动态变化。结果表明近4年北方春大豆品系灰斑病抗性总体表现良好,但仍有13.6%感病品系存在;黑龙江省参试品系的总体表现最好,抗性品系较多,感病和高感品系很少,而且具有丰富的免疫材料;吉林省缺乏抗性好的品系,感病的多且呈逐年增多的趋势;辽宁抗性品系多,但感病,尤其是高感的多,但高感品系年度间呈现显著下降趋势。其它省区的春大豆,免疫和抗病品系少,高感品系多,但近年来,抗病材料在不断提高,高感材料不断下降。该研究对于今后大豆灰斑病抗性育种和大豆品种审定及推广有重要的指导意义。To evaluate the resistance of northern spring soybean to race 7 of Cercospora sojina Hara, the regional test data of two hundred northern spring soybean lines were collected,and the resistant situation and dynamic trends of several main soybean production provinces were analyzed. Results showed that the resistance of northern spring soybeans was better on the whole, and there still had 13.6% sensitive lines. There were more resistant lines,less sensitive and high sensitive lines in Heilongjiang Province, where were also rich of high resistant lines. For Jilin Province,there were more sensitive lines with increasing trend and less resistant lines,while lack of high resistant lines. There were more resistant lines,more sensitive and high sensitive lines in Liaoning Province,but ratio of high sensitive lines decreased significantly from 2003 to 2006. For other Provinces, there ant lines increased and we hi ance for disease-resistant re less high resistant and resistant lines ,more sensitive ones, but resistgh sensitive ones decreased year by year. The results will provide guidbreeding, variety certification and releasing in soybean.
