【摘要】 以255份大豆种质为试验材料，利用混合碱模拟大庆市苏打盐碱地碱胁迫环境，在大豆种质芽期和苗期分别调查耐碱相关性状，结合BLINK和FarmCPU两种方法进行全基因组关联分析。结果表明，共检测到64个关联SNP位点，其中3:37513903、3:37490361、9:37033917等7个SNP位点相对稳定，可靠性较高；筛选到26个功能注释基因，根据功能注释和基因表达量，推测3个基因与耐碱相关，分别为Glyma.03G160200、Glyma.09G149900和Glyma.19G067400。更多还原

【Abstract】 In this study, 255 soybean germplasm were used as experimental materials, the mixed alkali was used to simulate the alkali tolerance environment of soda saline-alkali land in Daqing City.The alkali tolerance related traits were investigated at germination and seedling stages of soybean germplasm. BLINK and Farm CPU were used for genome-wide association analysis. The results showed that a total of 64 associated SNP loci were detected by the two methods, of which seven loci such as 3:37513903, 3:37490361 and 9:37033917 were relatively stable SNP loci with high reliability. A total of 26genes with functional annotation were screened out. According to functional annotation and gene expression level, three genes related to alkali tolerance were speculated, which were Glyma.03G160200,Glyma.09G149900 and Glyma.19G067400.更多还原
