摘要： 本文就我国各地推广的8个杂交稻组合,对强、中、弱三种致病力的白叶枯病菌系的抗性,进行遗传动态方面的分析。研究表明,大多数组合的杂交稻(F_1)抗性介于双亲之间,并偏向抗性水平较高的亲本。这些杂交稻的抗性与中亲值有显著相关,可按中亲值预测杂交稻的感病度。通过相对抗病优势的计算得知,杂交稻对白叶枯病的抗性,部分显性

Abstract: Genetic analysis was made on resistance of eight hybrid rice combi-nations to bacterial leaf blight,Xanthomonas oryzae,KS-6-6,KS-8-4and KS-1-2,which were strong,mediate and weak in pathogenicity.Theresults revealed that most of F1's susceptibility laid between its parentsand tended to the parent of
