【Abstract】 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.更多还原
