摘要:
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。
Abstract:
In this study, in order to evaluate the survival ability of BADH salt-tolerant transgenic soybean (SRTS) in saline-alkali environment, some indicators such as the competition ability(number of seedling, number of compound leaf, plant height), volunteer possibility, seed shattering and reproduction ability(growth period and yield) , were analyzed between SRTS, recipient variety and conventional soybean ‘Kangxianwang’ in saline-alkali land of Anda city.All kinds of soybeans were respectively planted 2 times in appropriate and not appropriate seasons. The results showed that in appropriate season, the competition ability of ‘SRTS’ was similar with ‘Kangxianwang’, but that of recipient variety was less than ‘SRTS’and ‘Kangxianwang’. In unfavorable season, the competition ability was not significantly difference between three varieties.Besides the SRTS viability of seed shattering and volunteering ability was obviously weaker. In appropriate season, SRTS reproduction ability was the best, the next was ‘Kangxianwang’, the weakest was recipient variety, and in unfavorable season the reproduction ability were similar between the three varieties. Therefore this showed that SRTS was fit for planting on saline-alkali soil.Comprehensive analysis of the above indicators, the results indicated that ‘SRTS’ surviving competition and adaptive ability were not stronger than non-transgenic plants due to import exogenous gene, and it had the lowest potential weediness.
