转基因技术——作物育种方法的一次革命

Transgenic Technology—A Revolution of Crop Breeding Methodology

作物转基因育种技术是指利用基因工程在原有作物的基因组中加入其它生物的遗传物质,从而培育新的优良性状的作物品种的一种技术。转基因技术是作物育种方法的一次革命。经过40年的发展,转基因作物如今已被广泛应用,在人类社会经济发展中做出了巨大贡献。本文回顾了作物转基因育种的简短历史,就当前转基因育种的主要目标性状进行了叙述,并对我国转基因作物商业化面临的挑战进行了分析。

Transgenic crops are plants used in agriculture, the DNA of which has been modified using genetic engineering techniques to produce new elite traits. Transgenic technology is a revolution of crop breeding methodology. Through 40 years’ development, transgenic crops have been widely adopted. This cutting age technology has made great contribution to the society and economy. The author reviewed the short history of transgenic crops and the traits of different crops have been modified by this technology. The challenges of transgenic crop commercialization in China were also discussed.
