摘要
杂交水稻不同于常规稻，它是一个群体结构同质、个体结构异质的杂种Ｆ１群体。本文从遗传、种子 生产、杂种优势以及栽培等方面分析了影响抗白叶枯病特性表达的因素；提出了为使抗白叶枯病特性正常表 达，在杂交稻三系育种，种子繁殖以及栽培上应注意的问题。
Hybrid rice, quite different from conventional rice, is an F1 population with same genotype,but the individual plants of it are heterozygous. The factors affecting the resistance expression against bacterial blight with respect to inheritance,hybrid seed production, heterosis and cultivation were discussed in this paper. In addition,suggestions were given as to hybrid rice breeding,seed production and cultivation,so that resistance against bacterial blight in hybrid rice may be fully expressed.
