为明确寒地核心种质抗病基因组成,利用日本7个单基因鉴别菌系（P-2b、研53-33、稻72、北1、研54-20、研54-04、稻168）接种鉴定了丽江新团黑谷×龙粳10号、丽江新团黑谷×垦稻10号组合10套F3系统,采用＂累积分布曲线法＂进行分析。结果表明：龙粳10号对P-2b、研53-33、稻72和北1四个菌系的抗性是由2对显性基因控制的,对研54-20的抗性是由3对显性基因控制的,对研54-04和稻168的抗性是由2对显性基因和1对隐性基因控制的。垦稻10号对研53-33的抗性基因是由2对显性基因控制的,对研54-20的抗性基因是由1对显性基因控制的,对研54-04的抗性是由2对显性互补基因控制。龙粳10号、垦稻10号可作为寒地水稻抗稻瘟病的核心种质,为抗病育种者选择亲本提供优质粳稻抗瘟源,并为寒地水稻核心种质库构建打下良好基础,在生产上应用具有重要意义。

In order to make clear the genetic constitution of the resistance gene of the core genetic resources in cold region,10 F3 populations of Lijiangxintuanheigu×Longjing No.10 and Lijiangxintuanheigu×Kendao No.10 were inoculated by the seven single gene controlled strains（P-2b,Ken 53-33,Ina 72,Hoku 1,Ken54-20,Ken 54-04,Ina 168）.Cumulative distribution curve method was applied.The results showed that the resistance of Longjing No.10 to P-2b,Ken 53-33,na 72 and Hoku 1 was controlled by 2 pairs dominant genes,to Ken 54-20 was controlled by 3 pairs dominant genes,to Ken 54-04 and Ina 168 was controlled by 2 pairs dominant genes and 1 pair recessive gene;that of Kendao No.10 to Ken 53-33 was controlled by 2 pairs dominant genes,to Ken 54-20 was controlled by 1 pair dominant gene,to Ken 54-04 was controlled by 2 pairs complementary dominant gene.Longjing No.10 and Kendao No.10 could be used as rice core germplasm of rice blast resistance in cold region to provide good rice blast resistance resource of parents selection for breeding,and made a good basis for building rice core germplasm bank in cold region and was important for rice production.
