Abstract: The commercialization of Genetically Modified Crops (GMC) has developed rapidly since 1997. On the one hand, GMC possess superior agronomic features and great economic benefits, on the other hand, they have caused great controversy because of its negative effects. Based on the features and the development of GMC, the negative effects of GMC on genetic diversity are evaluated in this paper, and some countermeasures should be taken in China.

Key words: GMC, genetic diversity, negative effect, countermeasure

摘要： 1997年以来,转基因作物的商业化取得迅速发展,一方面它具有优良的农艺性状和巨大的经济效益,但同时可能造成的负面影响也引起极大的争议。本文从转基因作物的基本特征、目前国内外发展状况,分析其对遗传多样性可能造成的负面影响,并提出我国应当采取的若干对策。
