摘要
吉林省在1963-2001年开展了稻瘟病菌生理小种的研究,先后提出了3套鉴别品种并采用3种命名方法,基本查清了吉林省生理小种的种类和优势小种。全省共有7群24个中国小种,以粳型小种为主,ZG1,ZF1小种为优势小种;用双名法命名,吉林省有44个吉林小种;开放式鉴别品种鉴定,吉林省有89个吉林小种;明确了吉粳60号、滨旭等品种抗病性丧失与吉林小种组成消长的关系,并对吉林省今后稻瘟病菌生理小种的研究提出了建议。
Studies on physiological races of blast fungus were conducted in Jilin province from 1963 to 2001. Three sets of differential cultivars were screened and three types of nomenclature methods were adopted successively. Types of races and predominant race(s) were determined basically. In Jilin province , there were 24 Chinese races belonging to 7 groups respectively, most of which were japanical, and the predominant races were ZG1 and ZF1. Based on double nomenclature method, there were 44 Jilin races in Jilin province, while there were 89 Jilin races when they were distinguished by a set of opening differentials. The relationship between resistance breaking down in cultivar Jilin 60, Binxu, etc. and constitution and dynamics of races was certain. Suggestions on investigating physiological races of blast fungus in the future were also proposed in this paper.
