摘要
选取我国具有自主知识产权的转基因抗除草剂玉米CC-2,研究其在栽培地与荒地环境中的生存竞争能力。试验结果表明,在栽培地环境中,转基因玉米CC-2与其对应的非转基因玉米在生育期、株高、产量等方面均一致,可正常生长;在荒地环境中,转基因玉米CC-2及其对应的非转基因玉米与杂草相比不具竞争优势,无杂草化风险。
We selected a transgenic herbicide-resistant maize variety CC-2 with self-owned intellectual property right as our research material. We studied its survival competition ability under field conditions and artificial waste- land conditions. The results showed that under field conditions, the transgenic herbicide-resistant maize variety CC-2 growed normally and was consistent with its non-transgenic control variety in growth periods, plant height, yield level and so on;under artificial wasteland conditions, the transgenic herbicide-resistant maize variety CC-2 and its non- transgenic control variety do not have any competition advantages over the weeds, thus can not evolve into weeds un- der our test conditions.
