摘要
１９９５～１９９６年，从贵阳地区采集分离小麦白粉菌有性世代菌株４５个，无性世代菌株６２个，分别接种在９个鉴别品种上。鉴定结果表明，两类菌源在主要生理小种的组成、出现频率以及对９个鉴别品种的毒性频率等方面是相似的。
Forty-five isolates of sexual generation and sixty-two isloates of sexual generation of Erysiphe f. sp. tritici collected from Guiyang during 1995~ 1996 were inoculated in nine wheat differential cultivars respectively. The resultxs and analysis showed that virulence constitution and emergence frequencies of the physiologic races and virulence frequencics to 9 what different cultivars in the two sources in E. g. t. sp. tritici were similar.
