摘　　要：2010年和2011年对129份芝麻种质资源(包括10份国外资源)进行了茎点枯病抗性鉴定及评价。结果表明,未发现免疫类型,高抗品种和高感品种所占比例低,感病品种占比例较大。2a鉴定抗性表现均在中抗以上的种质资源6份,分别为ZZM0565、ZZM0570、项城大籽白、新蔡选抗、河南商水农家种和KKU3;表现高感的种质资源5份,分别为ZZM1080、ZZM1102、ZZM0146、ZZM4177和ZZM2388。江淮一年两熟夏芝麻区的抗源材料最多,其次为华北一年一熟春芝麻区。The resistance of 129 sesame germplasms to Macrophornina phaseolina was determined and evaluated during 2010-2011. The results showed that there was no immune type among the varieties. The proportions of high resistant type and high susceptible type were lower, but that of susceptible materials was higher. A total of 6 varieties uniformly showed resistant in the two years,including ZZM0565, ZZM0570, Xiangcheng dazibai, Xincai xuankang, Shangshui farm spe-cies and KKU3. And there were 5 high susceptible varieties,which were ZZM1080,ZZM11l02, ZZM0146,ZZM4177 and ZZM2388,respeetively. Most of resistant varieties are distributed in the double cropping summer sesame areas of Yangze River and Huai River,followed by one cropping spring sesame areas in North China.
