摘要
黑龙江省地处高纬地区,气候冷凉,是中国著名的马铃薯产区,但同时也是晚疫病常年发生区,明确是否存在晚疫病菌A2交配型对当地的晚疫病防治方法和策略具有重要影响。本文利用晚疫病菌A1和A2标准菌株,采用对峙培养法,对采自黑龙江省的马铃薯晚疫病菌进行了2年的交配型测定,结果表明,所测定的来自全省8个县市的109个菌株均为A1交配型,未见A2交配型。
Heilongjiang is located in high latitude, and cool in summer. It is well known for its potatoes, however late blight occurs frequently. It is important to know whether A2 mating type exists in Heilongjiang, and this may help to develop an effective method and strategy for late blight control. In this research, isolates collected from Heilongjiang were tested for A2 mating type using standard strains and dual culture method. The results indicated that the 109 isolates collected from 8 counties （cities） of Heilongjiang were all A1 mating type, and no A2 was detected.
