- Abstract:
- A pot experiment was conducted to explore the tolerance and accumulation to Cd in 11 soybean varieties of South China.The biomass and yield of 11 soybeans varieties at high concentration of Cd treatments decreased significantly than control.Based on relative biomass and relative dry seed weight,Guixiadou 2,Brazil 3 varieties were tolerant varieties,and Huaxia 3,Gui M32,Brazil 15,Guizao 1 and Gengqing 82 were medium,while Zhonghuang 24,Brazil 10,Fudou 234 and Huaxia 4 were sensitive varieties.Significant genotypic differences in seed cadmium levels were found.The seed cadmium concentration was lowest in Huaxia 3 and Gui M32,and highest in Zhonghuang 24.Correlation analysis revealed that seed Cd concentration was significantly correlated with aerial part Cd concentration,but no significantly correlated with relative dry seed weight,relative aerial part dry weight and root dry weight.The results indicated that breeding soybean varieties with cadmium tolerance and lowcadmium accumulation in seed was possible.
