为评价转BADH基因耐盐碱大豆(SRTS)在盐碱条件下的生存能力,在安达市盐碱地比较了耐盐碱转基因大豆(SRTS)、受体大豆黑农35和当地栽培品种抗线王的竞争性(出苗率、复叶数、株高)、自生苗、种子落粒性和繁育能力(生育时期和产量)。分期播种4次,适宜季节和非适宜季节各2次。结果表明:在适宜季节SRTS和抗线王竞争性相似,而受体品种竞争性弱于二者,在非适宜季节3个品种的竞争性差异不显著;SRTS产生自生苗的可能性很小;SRTS的落粒性不强;在适宜季节SRTS的繁育能力最强,抗线王居中,受体品种最弱,SRTS更适于盐碱地生长;在非适宜季节3个大豆品种的繁育能力相似。综合分析上述指标,由此表明SRTS并没有因为转入外源基因而具有更强的适应能力和生存竞争能力,自身杂草化风险很小。
In order to evaluate the viability of transgenic salt-tolerant Soybean (SRTS) in salinity-alkalinity condition, salt-tolerant transgenic soybean (SRTS), receptor soybean Heinong 35 and local cultivars Competitive (emergence rate, compound leaf number, plant height), self-emergence, seed shattering and reproductive capacity (growth period and yield). Staged sowing 4 times, suitable for the season and non-suitable season 2 times each. The results showed that SRTS was similar to resistant line Wang in competitive seasons, while the competition of recipient lines was weaker than that in the suitable season. There was no significant difference in competition among the three varieties during the non - suitable seasons. The SRTS was not shattering. SRTS had the best ability to breed SRTS in the proper seasons, and the most resistant line was the middle one. The varieties of SRTS were the weakest and SRTS was more suitable for the growth of saline-alkali soil. The reproductive capacity of the three soybean cultivars was similar in the non-suitable seasons. Comprehensive analysis of the above indicators, thus indicating that SRTS is not due to the introduction of foreign genes and have a stronger ability to adapt to survive and survive, their own risk of weeds is small.
