| 摘 要： | 以2005、2006、2008年采集于黑龙江省哈尔滨市的17份马铃薯晚疫病菌株和2006年采集于黑龙江省8个地点的46份菌株(均为A1交配型)为试验材料,利用21对EST-SSR引物,分别对菌株与采集年份以及菌株与地理来源的相关性进行了聚类分析。结果表明:在相同地点采集的晚疫病菌株与采集年份之间具有一定的相关性;在相同年份采集的晚疫病菌株与地理来源之间也具有一定的相关性。

| Abstract: | In this research，17 Phytophthora infestans isolates collected in Harbin in 2005, 2006 and 2008, and 46 isolates（all A1 mating type）collected from 8 sites of Heilongjiang Province in 2006 were used as experimental material. Clustering analyses were conducted on the relativity between P. infestans strains isolated in different years and from different geographical sources by 21 EST-SSR primer pairs, respectively. The results indicated that there was certain relativity between P. infestans strains collected in the same locality with the collecting year, and also there was certain relativity between P. infestans strains collected in the same year with geographical sources. |
