用人工接种的方法在室内测定了90—2菌株对水稻野败型不育系和保持系的致病性及90—2菌株毒素对两种水稻材料的毒害作用,结果表明 90—2菌株对水稻野败型雄性不育细胞质有显著的专化侵染作用。
The pathogenicity of 90-2 strain to wild-type male sterile lines and maintainer lines and the toxic effects of 90-2 strain toxins on two rice materials were determined by artificial inoculation. The results showed that 90-2 strain pairs Rice wild-type male sterile cytoplasm has a significant role in specific infection.
