Genetic assay and study of crop germplasm introduced/originated in East Asia

对大麦、小麦、大豆、甜瓜等重要作物的植物遗传资源进行了探索，并通过12次野外考察成功引种。通过对多种植物遗传资源的分析，获得了与这些作物的进化、传播和适应有关的一些重要新发现，并发表在科学论文和书籍中。我们还鉴定了几个可用于改良重要农艺性状的材料。这些新资源可用于各种作物的育种计划，也可用于鉴定新基因的基础研究。

Plant genetic resources of important crops, including barley, wheat, soybean and melon, have been explored in Asian countries through which crops were introduced to East Asia, and successfully introduced through a total of twelve times of field expedition. Several important new findings related with the evolution, transmission, adaptation of these crops have been obtained by the analysis of diverse plant genetic resources, and published in scientific papers and books. We also identified several accessions which can be used for the improvement of agronomically important traits. Such novel resources can be utilized in breeding program of each crop, as well as for basic research to identify novel genes.
