Abstract

With the development of genetically modified crops, people worried about the potential hazards of genetically modified crops on the environment rising, and so into the commercial cultivation of genetically modified wheat before them the necessary environmental safety evaluation. Transgenic wheat ecological impact of its wild relatives is an important aspect of environmental safety assessment of genetically modified wheat. To carry out research in this area, the types and distribution of wild relatives of wheat in China is necessary to have detailed research. Sort of wild relatives of wheat species and their distribution data, and draw out the maps and maps of the various genera of wheat wild relatives and wild relatives of wheat in China overall distribution condition details understanding. Also wheat flowering period of wheat-growing areas (Shandong Province, Henan Province and the northern part of Jiangsu Province) wheat field wheat the Wild Relatives weeds resources to investigate. Finally, on the the transgenic wheat Wild Relatives diversity impact experiments Tanaka weeds resources investigation. The conclusions are as follows: 1, rich in species of wild relatives of wheat in China, and are widely distributed. China occupies an important position in the history of wheat origin. The distribution of the wild relatives of wheat contains 11 genera. 2, according to maps of the wild relatives of wheat, we can know the distribution of most of the wild relatives of wheat in China's north, northwest and southwest provinces. Distribution in the provinces of North and South is not very rich individual genera distributed only some provinces in the south. Xinjiang, Gansu, Shaanxi, Tibet, Yunnan is the main distribution of provinces, the main wheat producing areas of distribution of the species is not very abundant, and the population density is very small. In wheat flowering period, the main wheat producing areas (Shandong Province, Henan Province and the northern part of Jiangsu Province) in winter wheat fields of wild relatives and weeds resources survey. Survey results, we found that the distribution of wild relatives of wheat 8. Which steadily of wheat and Roegneria distributed widely, and population density. In addition, the survey also found that the distribution in the wheat fields and around 179 weed species belonging to 33 families respectively. But the region was not significantly different. 4 weeds resources survey their Wild Relatives diversity in the planting of the first year of the experimental field of genetically modified wheat. The accumulation of the data of the first year, and lay a good foundation for the subsequent comparison of the data. Found from the experimental situation, the need to plant new closely related plant species. According to the findings of the wheat field, this time we chose a relatively ubiquitous steadily in the local wheat and Roegneria. To environmental safety evaluation of transgenic wheat, it is necessary to clear the specific distribution of wild relatives of wheat in China, in order to their specific targeted research. Investigation, it is clear the specific distribution of its growth habit of wheat wild relatives of wheat wild relatives of wheat-growing areas in China. Environmental safety assessment to identify specific objects and the basic characteristics of the object of the study provides a good basis for data.
