In order to determine the glyphosate tolerance of wild soybean,the glyphosate tolerance of 47 wild soybean materials collected near Yanshan Mountain was identified by petri dish identification method.By measuring the germination potential,germination rate,cotyl length and radicle length of wild soybean materi-als,and combining correlation analysis,principal component analysis and membership function evaluation,the comprehensive score of wild soybean glyphosate tolerance was calculated.The results showed that the 8 traits were transformed into 2 principal components,and the cumulative contribution rate was 90.43％.The tolerance level was divided into 4 levels.Glyphosate tolerance of wild soybean materials 2011-8 was the high-est and glyphosate tolerance of wild soybean materials 2011-42 was the lowest.The results showed that petri dish identification method was a fast and accurate method to evaluate glyphosate tolerance of wild soybean,and could be used for screening wild soybean glyphosate tolerance materials.
