| 摘 要： | 1991年测定了昌宁县的21个单孢菌株,分别为B13,C13,E1,E3,F1,G15群6个小种.与1984年测定结果相比,小种种群有所变化,其优势小种除原有的G1外,又增加了E1和E3两个.同时还测定了昌宁县水稻栽培品种对当地21个单孢菌株的感染百分率,以便客观地评定品种的抗性.

| Abstract: | In 1991 twenty-one spores in of nice blast Changning,Yunnan,were tested of which five groups and six races,were identified they are B13,C13,E1,E3,F1, G1,respectively.As compared with areknown maces of 1984,the rsce population hsve someqhat changed.Two dominant races E1 and E3 have been added besides the former dominant race G1.In order to obgectively evaluate the resistance of rice species,the infective percentage of rice species from Changning to the focal twenty-onespores have also been Tested at the same time. |
