Genetic assay and study of crop germplasm in and around China (2nd)

各作物组分别进行了以下采集和考察。大米组：1998年，我们进入中国云南，经过老挝。在这次旅行中，我们收集了原始的水稻品种和其他作物和蔬菜，这些作物和蔬菜种植在各自的田地里。未发现野生稻品系。所有的品种都是来自刀耕火种地的旱地品种。中学时，我们的成员进入了中国南方的广西。另一个成员加入了北越。沿途收集了几种水稻品种。然后，这些成员在越南中部山区看到了原始的旱稻品种。接下来我们参观了老挝中部，收集了野生和栽培的水稻品种。大麦、小麦组：1998年与四川农业大学合作，在四川省进行调研采集。尽管特大暴雨和洪水摧毁了道路，但几乎所有预期的目的都得到了满足，我们不得不改变原定的计划和路线。1999年与尼泊尔加德满都特里布万大学的合作研究人员成功地在尼泊尔和不丹进行了研究调查，目的是获取植物资料，并与中国科学院昆明植物研究所的同事在云南省西北地区和中部地区收集了植物资料。他们将为我们提供这一地区迄今所缺乏的关于大麦和小麦的知识。大豆类群：对中国南方、印度尼西亚和尼泊尔大豆地方品种的遗传多样性和农业特征进行了两年的研究。人们对主要生活在中国南方丘陵地区的“苗”、“侗”、“哈尼族”和“傣族”等少数民族培育的土种特别感兴趣。此外，还对中朝边境鸭绿江流域野生大豆的分布和生态特征进行了探索。少

Each crop group went to the following collection and investigation trips.1. Rice group : In 1998, we entered into Yunnan in China and went through Laos. In the trip, we collected primitive rice cultivars with other crops and vegetables which were cultivated in respective fields. Wild rice strain could not be found. All collections were upland cultivars from slash-burn fields. Secondary year, our member entered in Guangxi in south China. And another member joined together at north Vietnam. Several rice cultivars were collected along the trip. Then, these members have been central Vietnam in mountain areas and seen primitive upland rice cultivars. Next we have seen central Laos and collected wild and cultivated rice cultivars.2. Barley and wheat group : A survey trip for research and collection was carried out in Sichuan Province co-operating with Sichuan Agricultural Univ. in 1998. Almost all the purposes expected were satisfied though the extraordinally heavy rainfall and flood destroy … More ed roads and forced us to change our scheduled plan and route. Research surveys in 1999 were successfully made in Nepal and Bhutan with collaboratory researchers of Tribuvan University in Kathmandu, Nepal, which aimed to get plant materials and informations were collected in the north-western district and the central area of Yunnan Province with co-workers in Kunming Institute of Botany, Chinese Academy of Sciences. They will provide us with so far lacking knowledge on barley and wheat in this area.3. Soybean group : Genetic diversity and agricultural features of soybean landraces in southern China, Indonesia and Nepal were examined for tow years. The special interest was taken in the landraces which have been cultivated by minorities such as "Miao", "Dong", "Hani" and "Dai", who are living mainly in hilly regions of southern China. In addition, distribution and ecological features of wild soybeans were explored in the river basin of the Yalujian River which is running along the North Korean border. Less
