摘　　要：2004-2006年，通过对南宁、玉林、百色等广西部分地区薏苡种质资源进行考察，共收集到117份栽培和野生薏苡资源，并种植在试验地保存。通过对这些种质资源的农艺性状进行观察鉴定，并选择农艺特性好的材料进行育种，目前已育成3个品种，可应用于农业生产。为了了解来源于中国广西、日本、韩国的薏苡的多样性，对77份薏苡资源进行SSR分析，结果表明，按亲缘关系可将77份薏苡资源分为两大类群。其中3份来自韩国的薏苡资源遗传背景非常相似，组成一个大类群；其余薏苡资源则构成另一个大类群。研究还发现，种质材料的遗传差异与其地域来源没有明显的关系。The germplasm resources of Job＇s tears were investigated in Nanning, Yulin, Baise cities from 2004 to 2006, and 117 accessions of cultivation and wild Job＇s tears were collected and planted in test field. The agronomic traits were observed and recorded, and the varieties with excellent agronomic traits were selected for breeding. Up to today, 3 varieties were got, which could be used in agricultural production. In order to know the genetic diversity of Job＇s tears in Guangxi of China, Japan and Korea more clearly, SSR analysis was carried out for 77 accessions from the 3 cities. The results showed that 77 accessions were sorted into two groups according to their genetic relation. Three accessions of Job＇s tears from Korea composed a group because their genetic background was very similar. Other Job＇s tears composed another group. Moreover, it was found that genetic diversity of Job＇s tears resources wasn＇t associated with their origin obviously.
