| 摘 要： | 通过对DNA提取方法的改良，随机引物的选择、RAPD反应条件的筛选，建立文心兰品种变异RAPD分子标记检测技术。利用该技术对3个母本园品种和1个试管苗品种进行RAPD检测，结果是品种“黄金2号”和“黄金3号”未发现变异；7个引物对品种“新奇士”共扩增出63条清晰带，3个样品带型发生变化，样品变异率为10％；14个引物对“黄金2号”试管苗共扩增出119条清晰带，9个样品带型发生变化，样品变异率为9．4％。结果表明，该技术能有效用于文心兰品种的变异检测。

| Abstract: | A RAPD molecular technology for detection of genetic variation of Oncidium was established through the improvement of DNA extraction methods and selection of random primers and RAPD reaction conditions. With this technology, 3 Oncidium varieties and an in vitro Oncidium variety were detected using the RAPD marker. Oncidium varieties Golden No.2 and Golden No. 3 were not found to have genetic variation. From the variety Sunkist a total of 63 clear bands were amplified by 7 primers, and 3 samples varied in th... |
