高油酸转基因大豆HOA_(80)生存竞争能力检测

Assessment of Competitive Ability for a High Oleic Acid GM Soybean Line ‘HOA_(80)’

本试验对高油酸转基因大豆HOA80、受体大豆SW80和常规对照大豆吉育71开展荒地生存能力、繁育能力等方面的安全检测。结果表明:正常播种条件下,高油酸转基因大豆的生存竞争能力、繁育能力等方面与受体大豆相一致;与杂草相比,3个大豆品种表现为生长速度慢、覆盖度小和繁殖力低等。在地表撒播条件下,3个大豆品种均不能成苗。由此可见,高油酸转基因大豆没有增强其自身生存能力和繁育能力,也没有与杂草相竞争的优势,对农业环境生态安全无影响。

In this study,comparative investigation on the competitive ability,reproduction ability of a high oleic acid GM soybean line＇HOA80＇,recipient variety＇SW80＇and a non-GM cultivated variety＇Jiyu 71＇was conducted in the natural agro-ecological environment.The results showed that ＇HOA80＇ exhibited similar competitiveness and reproduction as that of＇SW80＇and＇Jiyu 71＇in a favorable situation.All three varieties tested exhibited slower growth rate,less soil coverage,unable to mature and set seed when planted under the uncultivated soil.While been sowed at the surface of the same type of soil,all seeds could not even germinate.It is concluded that the high oleic soybean line＇HOA80＇is likely to present the lowest weediness potential in Jilin agro-ecological environment when imported as raw materials for industrial processing.
