对于稻瘟病的自然传播和水稻病害的危害,同其它病害一样,最合理而有效的防治办法,就是选育生产上具有抗性的品种。为了培育抗病品种,应该把区域化的品种与抗瘟稻病类型的品种异种交配,利用导入的免疫力,以提高感病类型的抵抗力。然而,在国内文献中,没有关于水稻该遗传特点的报导,只有其后代的类型对比。 因为母本的细胞质这个性状能够遗传,为了获得免疫类型,日本学者H和曾建议按照凯武热娃S1974年提出的方法进行控制 杂交。 我们工作的目的在于探明:在反交的情况下,稻瘟病抗性的遗传特点。 当杂交时,把易感的本国新育成的品种和远东的品种结合在一起,采用单株选择的方法育出了所 As for the natural transmission of rice blast and the harm of rice diseases, like other diseases, the most reasonable and effective control measures are breeding resistant varieties. In order to cultivate resistant varieties, the regionalized varieties should be cross-linked with the varieties of the blast-resistant rice type, and the imported immunity should be used to improve the susceptibility of the susceptible types. However, in the domestic literature, there is no report about the genetic characteristics of rice, only the type comparison of its offspring. Because the cytoplasm of the female parent can inherit this trait, in order to obtain the type of immunity, the Japanese scholar H and Tsang proposed the hybridization of the control according to the method proposed by Kewarva in 1974. The purpose of our work is to prove that: In the case of anti-cross, the genetic characteristics of rice blast resistance. When hybridized, the susceptible native new breed and the Far East breed are combined together and the individual selection method is used to breed
