Data Survey and Analysis of the Transgene Flow Frequencies and Distances in Major Crops Ⅳ.Maize
摘要
Abstract
Along with the rapid development of transgenic maize in recent two decades, maize has become the second largest transgenic crop worldwide. Parallelly, the research on maize gene flow and out-crossing has also been strongly promoted. It is known that 84%～92% of pollen grains deposited within 5 m from donor plant due to the maize pollen grains are relatively large and heavy. Based on the accumulated international data on transgene flow in maize, the maximum distance of transgene flow at a threshold value of 0. 1% (MTD0.1% ) is to be 100～119 m. In order to study the co-existence of transgenic and non-transgenic maize after the large scale commercialization of transgenic maize, scientists have collected samples from non-transgenic maize surrounding the transgenic maize planting area. The data has shown that the MTD0.1% is 80 m.关键词
