应用２０个随机引物对华南地区番茄主栽品种之一———粤星及其亲本的基因组ＤＮＡ进行了ＲＡＰＤ分析，发现７个引物可以在粤星及其亲本的ＲＡＰＤ图谱中形成多态性差异，其中引物Ｐ１８可应用于粤星番茄种子中混杂的母本类假杂种的检测。
Using 20 random primers, RAPD analysis of genomic DNA of one of the main tomato cultivars in Guangdong Province and their parents in southern China showed that there were 7 polymorphisms in the RAPD patterns of Guangdong star and its parents , In which the primer P18 can be applied to the detection of mixed parental fake hybrids in Cantonese tomato seeds.
