| 摘 要： | 1991年测定了昌宁县的21个单孢菌株,分别为 B_(13),C_(13),E_1,E_3,F_1,G_1 5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 G_1外,又增加了E_1和 E_3两个.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 B_(13),C_(13),E_1,E_3,F_1, G_1,respectively.As compared with areknown maces of 1984,the rsce population hsve someqhat changed.Two dominant races E_1 and E_3 have been added besides the former dominant race G_1.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. |
