以去雄小麦为受体 ,在 10m范围内小麦花粉可在任何方向发生有效漂移 (使受体结实 ) ,花粉的最远有效漂移距离可达 80m。以不去雄的小麦、柱穗山羊草和卵穗山羊草为受体时 ,在距花粉源 1m的范围内 ,小麦间的异交率最高为 0 2 4 %、小麦与柱穗山羊草和卵穗山羊草间的异交率分别为 0 2 5 %和 0 ,花粉的最远有效漂移距离可达 2 0m。依照欧盟的标准 ,非转基因小麦即使与转基因品种相邻种植 ,其产品中的转基因成分也不会超标。在麦类近缘野生植物的起源中心及主要分布区 ,释放转基因小麦要特别慎重。 With the male sterility of wheat as the receptor, the wheat pollen effectively drifts in any direction within 10m (the receptor is strong), and the most effective drifting distance of the pollen can reach 80m. When using non-sterilized wheat, Coltsfoot, and Echinochloa crus-galli as receptor, the highest rate of out-crossing was 0 2 4% within 1 m from the pollen source, The outcrossing rates of oat and goat grass were 0 25% and 0 respectively, and the longest effective drifting distance of pollen was 20 m. According to EU standards, non-GMO wheat, even grown adjacent to GM varieties, will not exceed GMOs in its products. In wheat germplasm centers of origin and the main distribution of wild plants, the release of genetically modified wheat should be particularly careful.
