| 摘 要： | 1986年从全国采集到小麦秆锈病标样175份,繁殖存活125份,成活率为71.4%。在185个菌株中鉴定出21C3、34C2、34、34C1和34C35个生理小种,出现频率各为75.7%、14.6%、4.3%、3.8%和1.6%。21C3仍为当前优势小种,34C2居第二位。小麦秆锈菌的离体叶培养通过3年对比试验,已进入实用阶段。

| Abstract: | Out of the 175 uredial samples of Puccinia graminis var.tritici col-
lected from thirty-two sites in sixteen provinces and autonomous regions in
1986,125 survired and their survival rate was 71.4%.Five races were iden-
tifed from the 185 isolates from the surviving samples.They were races
21C3,34C2,34,34C1 and 34C3,and their frequencies were 75.7%,14.6%,
4.3%,3.88% and 1.6%,respectively.Race 21C3 still remained dominant
and race 34C2 occupied the second position.
In addition,the detached host leaf culture method for identifying
races of stem rust hast has been successfully put into use. |
