为探明湖南省草莓灰霉病菌群体遗传结构、分化及变异规律，采用荧光标记技术对湖南省9个地理菌群的180株草莓灰霉病菌基因组DNA进行SSR分析。结果表明：9对SSR引物共检测到56个观察等位基因（Na），平均值为6.22；有效等位基因（Ne）为1.27～4.89，平均值为3.44；不同位点的基因多样性指数（H）为0.21～0.80，平均值为0.65；不同位点Shannon’s信息指数（I）为0.37～1.83，平均值为1.34。供试180株样品9个SSR多态性位点上多态性信息量PIC变化范围为0.13～0.91，不同位点PIC差异大，这一规律与I和H基本一致。不同SSR位点总的遗传多样性（Ht）为0.21～0.77，平均值为0.65；群内遗传多样性（Hs）为...

In order to investigate the genetic structure of srawberry mould fromBotrytis cinerea,its differentiation and veriation regulatory,this paper carried out SSR marker analysis on DNA of 180 srawberry mould fromBotrytis cinereagenomes,collected from 9 locations of Hunan Province.The result indicated that a total of 56 alleles(Na)for 9 SSR loci were detected,the average value was 6.22.The effective number of alleles(Ne)ranged from 1.27-4.89,with an average value of 3.44.The Nei’s gene diversity(H)varied from 0.21-0.80,with an average value of 0.65...
