Assessment of competitive ability for a salinization resistence transgenic soybeans line.

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.
