摘要： Tocopherols are natural antioxidants that increase the stability of fat-containing foods and are well known for their health benefits. To investigate the variation in seed tocopherol composition of soybeans from different origins, 493 soybean accessions from different countries (China, USA, Japan, and Russia) belonging to 7 maturity groups (MG 0-VI) were grown in 2 locations (Beijing and Hainan Provinces of China) for 2 years (2017 and 2018). The results showed that significant differences (p < 0.001) were observed among the accessions and origins for individual and total tocopherol contents. The total tocopherol content ranged from 118.92 mu g g(-1) to 344.02 mu g g(-1). Accessions from the USA had the highest average concentration of gamma- and total tocopherols (152.92 and 238.21 mu g g(-1), respectively), whereas a higher level of alpha-tocopherol (12.82 mu g g(-1)) was observed in the Russian accessions. The maturity group of the accession significantly (p < 0.001) influenced all tocopherol components, and higher levels of alpha-, gamma-, and total tocopherols were observed in early maturing accessions, while late-maturing accessions exhibited higher levels of delta-tocopherol. The inclination of tocopherol concentrations with various MGs provided further evidence of the significance of MG in soybean breeding for seed tocopherol components. Furthermore, the correlation between the seed tocopherol components and geographical factors revealed that alpha-, gamma-, and total tocopherols had significant positive correlations with latitude, while delta-tocopherol showed an opposite trend. The elite accessions with high and stable tocopherol concentrations determined could be used to develop functional foods, industrial materials, and breeding lines to improve tocopherol composition in soybean seeds.
