259个水稻品种对57个菌株抗性谱和抗性类型的研究结果表明。7个国内和8个国际鉴别品种以及11个日本抗瘟基因代表品种的抗病谱,除Tetep,Dula r.K_3,东农363,NP-125和K_1较广外,其余品种抗菌率在80%以下,对湖南巳知的小种鉴别力不强。所有供试品种中,抗菌率90～100%的有110个品种。占供试品种42.5%。根据选择9个代表菌株的测定结果,可将抗病率在90%以上的110个品种分为9个抗病类型(各类型代表品种为赤块矮选,TKM_6,农试4号,红脚粘,城特235。矮脚白米籽,滇瑞137,辐包22和密阳147)。朝六早为感病类型,本文还讨论了抗性谱和抗性类型划分的意义与问题。
The results of the study on resistance spectrum and resistance type of 57 strains of 259 rice cultivars showed. The anti-disease spectrum of 7 domestic and 8 international differentiated cultivars and 11 Japanese blast-resistant cultivars showed that the antibacterial rate of other cultivars except Tetep, Dula r. K_3, Dongnong 363, NP-125 and K_1 was more than 80 % Below, the known species of Hunan discriminant is not strong. All the tested varieties, the antibacterial rate of 90 to 100% of 110 varieties. Accounting for 42.5% of the varieties tested. According to the results of 9 representative strains selected, 110 varieties with more than 90% disease resistance can be divided into 9 types of disease resistance (the types of representative varieties are short block, TKM_6, No.4 Sticky, city special 235. Dwarf white rice seed, Dianrei 137, Radix 22 and Miryang 147). Six as early as the susceptible type, this article also discussed the significance of the resistance spectrum and the type of resistance and problems.
