| 摘 要： | 以１０套同核异质（Ｎ、Ｃ、Ｒｂ、ＥＳ）品系及Ｃｍｓ－Ｃ胞质背景的３个杂交种（Ｆ１）为试材．对田间观测的４个病理指标的鉴定和分析结果表明：（１）除乳熟期病情指数外，其余３个病理指标的结果显示出Ｃ小种对Ｃ群ＣＩ亚群雄性不育胞质具有专化性侵染的特点．但在不同病理指标、不同核型之间所表观的专化性程度却有较大差别；ＣⅡ、ＣⅢ亚群胞质无专化侵染现象．（２）Ｃ小种的致病力小于Ｔ小种．

| Abstract: | Through study on the four phytopathological indexes with 10 sets of different male-sterile cytoplasm subgroups of the C group maize in same nucleus respectively and 3 cross-hybrids in Cms-C, the result shows: (1) the result of the 3 phytopatological indexes except one index indicates that subgroup C1 (Cms-C) of the C group maize (Zea Mays L. ) was specially susceptible to Bipolaris maydis race C. But there are great defferences among the different phytopathological indexes and different host nucleus. (2)the infection of race C isn't more serious than race T. |
