Identification and Screening of Alkaline Tolerance of Wild and Semi-wild Soybeans at the Germination and Seedling Stages in Heilongjiang Province
摘要
Abstract
Saline-alkali stress severely restricts soybean(Glycine max(L.)Merr.)yield at all stages of crop growth.Selecting new salt-tolerant varieties and exploring salt-tolerance genes are important ap-proaches to enhancing soybean productivity.To explore salt-tolerance genes in wild and semi-wild soybeans and cultivate new salt-tolerant soybean varieties,using wild and semi-wild soybeans from Heilongjiang Province as materials,a mixed saline-alkali solution with a molar ratio of NaCl∶Na2CO3∶NaHCO3∶Na2 SO4 of 1∶1∶9∶9 was applied for treatment.Salt-tolerance tests and selections were con-ducted on the seedlings and seedlings of wild and semi-wild soybeans under the conditions of a saline-alkali solution concentration of 140 mmol/L and pH=9.5.Results showed that under the conditions of a saline-alkali solution concentration of 140 mmol/L and pH=9.5,10 high salt-tolerance materials were selected from 90 wild soybeans,including Y154,Y176,Y161,Y35,Y29,Y17,Y89,Y126-1,Y128,and Y97.Under the conditions of a saline-alkali solution concentration of 100 mmol/L and pH=9.2,7 high salt-tolerance materials were selected from 54 semi-wild soybeans,including BY137,BY129,BY30,BY12,BY27,BY60,and BY73.关键词
