对小麦白粉病菌生理小种三个鉴别寄主的抗性基因分析
The Resistant Gene Analysis for Three Differential Hosts of Wheat Powdery Mildew Race
【摘要】 采用基因推导法分析了三个鉴别寄主的抗性基因：白免３号和肯贵阿１号含有Ｐｍ４ａ：小白冬麦的抗性受一对隐性基因的控制，其抗谱不同于所有供试单基因系的抗谱。
【Abstract】 The genes for resistance to Erysiyte Grami,Graminis f.sp.tritici were analyzed in three Chinese race differential hosts by means of gene postulation. Bat Mian 3 and Keng Guia 1 have the gene Pm4a.The resistance of Xiao Bai Dong Mai is determined by a recessive loci.Its resistance pattern is different from all that of lines with known single resistant genes used in the paper.
