Abstract:
Optimization of soybean fatty acid is one of the most important breeding objectives.In this study,a total of 150 soybean germplasms from Northeastern China were planted in three tested sites including Harbin,Nanning and Sanya.The oil content and fatty acid component of the tested seeds were measured to investigate the relationship within oil content and five fatty acid and with main agronomic traits of soybean as well as the influence of different environments on soybean fatty acids.The results showed that the accumulations of saturated and unsaturated fatty acid,particularly the latter,were influenced by the environments.Oil content of soybean germlasms was relatively stable in the three tested sites.Oleic acid showed a highly significant negative correlation with linoleic acid,palmitic acid and linolenic acid in all the three tested sites.Variation coefficient of various fatty acids was different,of them,that of linolenic acid and stearic acid were higher,linoleic acid variation coefficient is lower.Variation coefficient among different environment was small.The correlation analysis showed oleic acid and linoleic acid,linolenic acid,palmitic acid showed a significant negative correlation in three environments,and the linoleic and linolenic acid content was significantly positively correlated.Oil and oleic acid was significantly positively correlated with linolenic acid,and it was significantly negatively correlated.
