以前期试验获得的两个耐盐转GsSAMS基因苜蓿株系A-21和A-23为试验材料，进行产量性状和形态性状的调查与分析，为其产业化提供依据。结果表明，在产量性状上，两个转基因苜蓿株系春秋季的茎分枝数、产草量及干重与对照株系相比，不存在显著差异；在形态性状上，两个转基因苜蓿株系的生长速度、株高、节数及节间长度与对照株系相比，差异亦不显著。说明外源基因GsSAMS在苜蓿体内表达并未显著改变苜蓿的产量性状和形态性状。

The agronomic traits including the yield traits, morphological traits and quality traits of GsSAMS transgenic alfalfa (line A-21 and A-23) were investigated and analyzed statistically. Our results showed no significant differences between the transgenic and non-transgenic alfalfa plants in the number of branches, grass yield and dry weight. We also found no significant differences regarding to the growth rate in spring and autumn, plant height, the number of nodes and the node length. Taken together, our results indicated that over-expression of GsSAMS in alfalfa did not alter the agronomic traits of transgenic alfalfa.
