Genetic assay and study of crop germplasm in and around China (4th)

通过12次田间考察，在中国及周边地区摸索了大麦、小麦、大豆、甜瓜等重要农作物的植物遗传资源，并成功引种。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、传递、适应有关的一些重要的新发现，并发表了科学论文和书籍。我们还鉴定了几个可用于农艺性状改良的材料。这些新资源将被用于每种作物的育种计划，以及用于识别新基因的基础研究。

Plant genetic resources of important crops, including barley, wheat, soybean and melon, have been explored in and around China 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 by scientific papers and books. We also identified several accessions which can be used for the improvement of agronomical traits. Such novel resources will be utilized in breeding program of each crop, as well as for basic research to identify novel genes.
