Abstract
由花蓮、苗栗、屏東三處採集之大豆誘病標本，經單胞分離得九菌侏。於溫室行接種試驗結果，三種大豆品種對九種供試菌株均呈感病性。其餘三品種則對某些菌株顯示抗病性。供試五種荳科植物中紅豆不感病，綠豆則感病而不產生夏胞子堆，豇豆及刈薯等則因菌株之不同而呈現不同之感病反應。
於本試驗中大豆品種對銹病菌之反應無法確立抗感病基準，供試九菌株按其於荳科植物上之病原性，可分為六種不同之病原型：（l）菌株H-CH1侵入豇豆並產生夏胞子堆。（2）菌株M-T、H-CH2及H-NK5侵入豇豆，不產生夏胞子堆，侵入菜豆並產生夏胞子堆。（3）菌株H-S及H-P侵入豇豆及菜豆不產生夏胞子堆。（4）菌株K-P不侵入豇豆，但侵入菜豆並產生夏胞子堆。（5）菌株M-64-37不侵入豇豆及刈薯。（6）菌株KS-55S不侵入豇豆，但侵入刈薯，惟不產生夏胞子堆。
Nine isolates obtained by single urediospore isolation from rusted soybean leaves collected at three locations in this island were tested on the tentatively selected differential plants, consisting of six soybean varieties and five leguminous plants. No marked differences in pathogenicity of the isolates of the rust fungus were observed on the soybean varieties. However, the nine isolates could be separated into six pathogenic groups differring mainly in their reactions on three leguminous plants: 1) isolate H-CH1 infects and forms sori on asparagus bean; 2) isolates H-CH2, H-NK5 and M-T infect asparagus bean and kidney bean, but form sori only on kidney bean: 3) isolates H-S and H-P infect asparagus bean and kidney bean but no sorus formation on either one; 4) isolate K-P showing no pathogenicity to asparagus bean infects and forms sori on kidney bean; 5) isolate M-64-37 infects neither asparagus bean not short podded yam bean; 6) isolate KS-55S showing no pathogenicity to asparagus bean, infects short podded yam bean but no sorus fàrmation.
