摘要
The bacterial blight (Xanthomonas campestris pv. oryzae) resistances of 4 derived lines fromindica-japonica hybridization innoculated by Philippine races 1-6 and Zhejiang strains 1-5 are similar orstronger than DV85’s resistance to Philippine races and nearly same as DV85’s resistance to Zhejiangstrains. This results are much stronger than popularly planted check variety "Xiushui 11". Among the 4derived lines, ZD92152 is also resistant to seedling blast (mean score is 0.7), neck blast (mean score is0.7) and bacterial leaf streak (Xanthomonas compestris pv. oryzicola) (mean score is 3.9). At otherhand, the 4 derived lines’ indica-japonica behaviours were studies. ZD92147 belongs to japonica andZD92152 belongs to indica.
