１９８６～１９８９年鉴定了山东省７６０个大豆品种的耐盐性。从中筛选出芽期耐盐品种１４１份，苗期耐盐品种９０份，并筛选出２５个芽期和苗期均耐盐的大豆品种。不同大豆品种及同一品种不同生育期耐盐性不同，芽期与苗期耐盐性无明显关系；大多数耐盐品种来源于盐碱地和干旱少雨地区；耐盐品种一般植株较高，分枝较多，成熟偏晚，亚有限或无限结荚习性，籽粒较小，籽形椭圆或长（扁）椭圆形。
From 1986 to 1989, the salt tolerance of 760 soybean cultivars in Shandong Province was identified. A total of 141 salt-tolerant cultivars at budding stage and 90 salt tolerant cultivars at seedling stage were screened out and 25 soybean cultivars with salt tolerance at bud and seedling stage were selected. Salt tolerance of different soybean varieties and the same variety at different growth stages was different, and there was no significant relationship between salt tolerance at seedling stage and most of salt-tolerant cultivars. Salinity-tolerant cultivars originated from saline-alkali soil and arid areas with less rainfall. More mature, late, sub-limited or unlimited pod habit, smaller seeds, oval or long oval seed.
