摘要
根据生物间遗传学原理,分析了26个黄淮麦区小麦品种对15个叶锈菌系的抗性状况.抗性最好的品种是徐州174,毒力频率为33 3%,毒力频率低于60%的仅有百农64、徐州8697等7个品种.2号和3号叶锈菌系的抗源品种最多,有22个,而14号和15号叶锈菌系无一抗源品种.总之,供试品种的抗叶锈性较差.
The resistance of wheat cultivars from Huanghuai wheat region to 15 isolates of Puccinia recondita f.sp.tririci has been analyzed according to Interorganismal Genetics.The best one of the tested cultivars is Xuzhou174 with the virulent frequency of 333%.There are 7 cultivars,such as Bainong64,Xuzhou8697,whose virulent frequency is less than 60%.22 wheat cultivars can resist No.2 and No.3 isolates,whereas no wheat cultivars can resist No.14 and No.15 isolates.In the mass ,the resistance of all the tested wheat cultivars is unsatisfactory.
