基改油菜之花粉流動及隔離距離估計

Pollen Flow of GM Oilseed Rape and Estimation of Isolation Distance

摘要


基因改造作物雖然在部分國家已開放種植,但仍存在食用安全與環境保育的疑慮。基因改造作物所帶有的轉基因可以藉由基因流動的方式汙染鄰近之非基因改造作物或近源種植物,而最直接遏止基因流動的方法就是利用基改作物田與非基改作物田之間的空間隔離。本篇主要探討油菜的兩種花粉傳播媒介昆蟲與風對基因流動的影響,以及利用模式對隔離距離與污染率的配適,期望提供遏止基改油菜基因流動的有效方法。

Although the genetically modified crops have been cultivated in the open field in some countries, the concerns on the food safety and ecological environment still exist. The genes can be transferred from genetically modified (GM) crops to non-GM crops in the field or to their relatives by the pollen flow. The effective measure to avoid the pollen flow from GM crops to non-GM crops is keeping an isolation distance. The objective of this report is to review the behavior of gene flow in oilseed rape and the model related to the isolation distance and cross-pollination rate. The information can be the reference of minimizing the gene flow of GM oilseed rape.
