对抗稻瘟病品种特特普、窄叶青8号、珍龙13、金围矮和感病品种朝六早,朝阳1号过氧化物酶同功酶谱分析结果表明,抗病品种比感病品种多一条酶带。这条酶带可以通过抗,感品种之间杂交遗传后代。用稻瘟病菌株75-49和0209-1接种鉴定特特普,窄叶青8号、温选10号、红410、金围矮与朝六早、朝阳1号及其F1、F_2代,结果证实:特特普和窄叶青8号由二对显性基因控制抗病性,温选10号和红410由单显性基因控制,金围矮由二对隐性基因控制。过氧化物酶同功酶分析结果与通过人工接种鉴定亲本和后代抗性遗传结果是一致的。这些结果指出,过氧化物酶同功酶分析可用于水稻品种抗瘟性鉴定和抗瘟性遗传研究。
The results of peroxidase isoenzymes analysis of Teupu, Narrow Yeqing 8, Zhenlong 13, Jinweishuai and susceptible varieties Chaoluzaosa and Chaoyang 1 showed that the resistant varieties were more susceptible than the susceptible ones More varieties of an enzyme band. This enzyme band can pass anti-susceptible varieties cross between the genetic offspring. Inoculation of rice blast fungus strain 75-49 and 0209-1 was used to identify Tertull, Narrow Yeqing 8, Wenxuan 10, Red 410, Jinwei Dian and Chao-Liu-Zao, Chaoyang No.1 and F1, F_2 generation. Confirmed that: Tete Pu and Narrow Yeqing No. 8 by two pairs of dominant genes to control disease resistance, temperature selection No. 10 and red 410 controlled by a dominant gene, Jinwei dwarf by two pairs of recessive genes. The results of peroxidase isoenzyme analysis are consistent with the genetic resistance results of parents and offspring identified by artificial inoculation. These results indicate that peroxidase isoenzyme analysis can be used for rice blast resistance identification and blast resistance genetic research.
