河北省小麦品种与河北省小麦叶锈菌的相互作用研究(一)

摘  要：
本文指出了斯塔克曼(Stakman)等建立的研究禾谷类锈菌生理分化的概念和方法存在的一些问题。并改用以河北省的叶锈菌测河北省的小麦品种,来直接研究寄主和病原物的相互作用。试验用了来自河北省的叶锈菌菌株86个,分别测河北省的主要推广品种、将推广或参加区域的品系和抗源共24个。从毒力频率,可以看出已推广的品种都严重感染叶锈病。在将推广或参加区试的品系和抗源中都有感病、抗病和中间类型的材料。有5个品种,即石家庄74531、78—4020、PKB L—16、洛夫林10和洛夫林13是高度抗病的。从寄主和病原物伪相互关系可以看出有14种不同的毒性公式。从公式分析,可以看出2个以上的品种与一系列菌株的关系,即可以看出小麦品种的联合抗病性或叶锈菌的联合致病性。作者们认为,用这种方法直接研究寄主和病原物的相互作用,对抗病育种和生产提供的情报,要比单纯提供一份以编号对小种命名的小种名单要直接和有用得多。这种情报,对于选择品种进行杂交,考虑品种合理布局或进行生物间遗传学研究等都有好处。

摘  要：
The authors point out the problems of the concept and method of stu-dying the physiologic specialization of rust established by Dr.E.C.Stakman and prefer to study the host:pathogen interaction directly.Twenty four wheat materials belonging to commercial cultivars ofHebei,wheat selection in regional test and to be released and source of resistance have been inoculated respectively with 86 isolates of Puccinia recondita f.sp.tritici colleected from various regions in Hebei Province.The result shows obviously that all the commercial cultivars are high-ly susceptible with virulence frequency 89.5～98.8%.The selections in regional test and to be released and source of resistance are either highly susceptible,intermediate or highly resistant.Five varieties namely,shiji-azhuang 74531,78-4020,PKB L16,Lovrin 10,and Lovrin 13,coded by 9,10,18,23,and 24 respectively are highly resistant with virulence frequency 5.8,5.8,11.6,10.7 and 15.1% respectively.Based on the interactions of the 5 resistant varieties mentioned above with the leaf rust,14 virulence formulae can be formulated.The formula 9,10,18,23,24/occurs most frequently with the frequency of 67.44%, while/9,10,18,23,24 only occurs 2.32%.Pathogenicity association and resistance association can be analyzed from the formulae.The authors strongly beleive that with the purpose of serving breed-ing program,it is much better to provide the information of host.patho-gen interaction rather than merely providing a list of races named by numbers.The information of host.pathogen are direct and useful as breeding for resistance,deployment of genes and studying of interorgani-smal genetics are concerned.
