摘要: 当前生产上应用的瓠瓜品种众多,且商业品种间的遗传相似性愈来愈高,种子质量纠纷时有发生。为提供一种快速、准确、可靠的瓠瓜种子纯度检测方法,本研究以44份瓠瓜种质为试材,通过高通量测序自主设计开发适用于瓠瓜研究的SSR引物,从中筛选出8对诊断性引物,在此基础上建立基于SSR分子标记技术的瓠瓜种子纯度快速检测方法。根据本方法建立的瓠瓜主栽品种标准DNA指纹可高效鉴别瓠瓜种子真伪及纯度,满足瓠瓜种子产业化健康发展的需要。

Abstract: Current application of large number of commercial bottle gourd cultivars with very high genetic similarity has caused many disputes on seed quality. To provide a rapid, precise and reliable method for bottle gourd seed purity assay, we developed a set of SSR markers based on DNA sequences obtained from highthroughput sequencing. Eight of these markers were defined as diagnostic markers by genotyping a collection of 44 bottle gourd genotypes. Based on this, a rapid and precise SSRbased procedure as well as standard DNA fingerprints for bottle gourd seed quality survey was established, which will be beneficial for the industrialization of bottle gourd seeds.

Key words: bottle gourd, SSR, purity survey, genetic fingerprinting
