Analysis on the Diversity of Soybean Protein Content

[Objective] The aim was to explore the application range of hereditary of soybean cultivars and select better quality cultivars with higher protein content.[Method]Taking 113 cultivated soybean varieties and 20 wild soybean varieties around the world as materials,using Kieldahl method,the protein content were determined and researched,and the diversity of soybean content was analyzed.[Result] The protein content of wild soybean is among 49%-54%,and is high protein soybean,and the protein content of cultivated soybean is among 36%-51%,have both high protein cultivars and low protein cultivars.The variance analysis shows that the soybean protein content shows extremely significant differences,has obvious polymorphism.[Conclusion] High protein soybean was screened out to provide theoretical and technical reference for soybean cultivar identification,germplasm resource protection and development.
