摘要
1999～ 2 0 0 2年对广西水稻区试品种 (组合 )进行了白叶枯病抗性鉴定 ,结果在供试 198份杂交稻中抗性 级没有出现 , 级 18个 ,占 9.0 9% ;供试的 4 7份常规稻中抗性 级 1个 ,占 2 .13% ; 级 2 4个 ,占 5 1.0 6 %。应及早寻找抗 群的抗源 ,并加强菌系变异的监测工作。
The rice varieties (combinations) tested in regional trials were identified on resistance to Bacterial Leaf Blight (BLB) during 1999~2002. The results showed that none of the degreeⅠ and 18 of degree Ⅲ degree were identified in 98 hybrid rice combination; one of the degree Ⅰ (2.13%) and 24 of degree Ⅲ (51.06%) were examined in inbred cultivars. It ought to look for the resources with the resistance to group Ⅴ of the disease and strengthen the observation of the strain variation.
