摘要： 摘要：为了充分利用黑龙江省水稻抗稻瘟病资源，利用日本的7个致病性稳定的菌系对黑龙江省部分粳稻品种进行了抗瘟性分类。通过与12个鉴别品种的反应型比较分析，推断了部分品种的基因型。将141份品种划分为39个品种群，并初步推断了60个品种的基因型，为育种者提供抗源，也为开展抗病基因分析奠定了物质基础。

Abstract: Abstract: In order to utilize the resource of the rice in Heilongjiang Province resisting against the rice blast, we classified some japonica rice cultivars of Heilongjiang province according to the resistance to the blast using 7 stable pathogenicity Japanese strains. We inferred genetic types of parts of the species of the rice based on the analysis of their reactions to the comparison of 12 differential strains. As a result, we classified 141 rice cultivars into 39 ones, and primarily inferred the genetics types of 60 species, which has provided the cultivars with resistance source and paved the basement for carrying out the analysis on the resistance of the rice to the blast.
