The objective of this project research is to carry out a survey trip on wild Brassica campestris and B.oleracea in European countries and a collection of seeds of them on individual base to make analysis on the distribution of S-alleles, which are considered to participate in the recognition reaction of self-and nonself pollen/pistils.In order to investigate it in Germany we have visited Dr. Thomas Glades, institute of Plant Genetics and Crop Plant Research in Gatersleben, and made a trip to the place in where a wild B.campestris population was described to grow by kind help of him. However, the barley field was changed to pasture, according to very recent changes of agricultural situations, and we could not find any wild populations of this species in this country. Furthermore, it was suggested that this species is listed to be a possible species going to extinction.We have carried out a survey trip between Amsterdam and Utrecht in Netherland. Eight populations of B.napus was found on the creek sides and road sides. These populations, however, was considered to be escaped ones. B.nigra was also found near to some of these populations.At Folkestone, near to Dover, in England, we could find a good population of wild B.oleracea. They grow on the cliff against sea and the road on the base of cliff. More than hundred plants grew along the road for about 300 m. and we could obtain some seeds from them on individual base. Only few seeds were collected from each plant not to disturb the population structure of the population.It was revealed that wild B.campestris may grow at this moment near the Black Sea in Russia and Slovakia. It is not sure, but possibly grow as a weed in the field or rape cultivation in England or Denmark.This survey trip was partly successful in obtaining some seeds of B.oleracea, and we are going to make an analysis of S-alleles on this materials and to investigate the distribution and diversity of Salleles of wild populations.

该项目研究的目的是在欧洲国家进行野生胸罩露营动物和紫菜的调查之旅，并在个人基础上进行一系列种子，以对S-leartle的分布进行分析，这些分析被认为是参与自我和非自然花粉/犬类的识别反应。描述了野生bubspertis人口的地方，他的善良的帮助。但是，根据农业情况的最新变化，大麦领域变成了牧场，我们在这个国家找不到该物种的任何野生种群。此外，有人建议将该物种列为灭绝的可能物种。我们在荷兰阿姆斯特丹和乌特勒赫特进行了调查之旅。在小溪的侧面和道路侧发现了八个人群。但是，这些人口被认为是逃脱的。在其中一些人群附近也发现了B. Nigra。在英格兰多佛附近的Folkestone，我们可以找到良好的野生b.oleracea。他们在悬崖上生长在海上和悬崖底的道路上。沿着道路生长了大约300 m。我们可以从各个基础上从它们那里获得一些种子。从每种植物中收集了很少的种子，不打扰人口的人口结构。据显示，野生阶级的b.campestris此刻可能会在俄罗斯和斯洛伐克的黑海附近生长。不确定，但是在英格兰或丹麦的田间或强奸培养中可能会成长为杂草。这次调查之旅部分成功地获取了紫菜的某些种子，我们将在这种材料上对S-learters进行分析，并研究野生种群的salleles的分布和多样性。
