Abstract：Inordertoscreenouthigh-yieldandhigh-qualityLentinulaedodesvarietiessuitableforplantinginwestem Henan，1l majoragronomic traitsof24varieties were selectedas evaluation indexes，andcomprehensiveevaluation was carried out by grey corelation degreeand DTOPSIS.Theresults showed thatthecorrelation between the rankingof grey correlation methodand the ranking of yield was low （r=0.476） ，and the evaluation paid more attention to the balance of traits.Incontrast，therankingofDTOPSIS method was significantlycorrelated with the rankingof yield （r=0.941） ，which was closer to the breeding goalofhigh yieldand high quality.Both methods couldreflectthecomprehensiveperformance ofLentinula edodesvarieties toa certain extent.The maximum differencerateof Ci valueofDTOPSIS method was （204号 56.37% ，which was higher than the maximum diference rate of Gi value of grey correlation method 24.17% ，indicating thattheDTOPSIS methodbetter highlight thedifferencesandcomparativeadvantages among varieties.Therefore，the DTOPSIS method is more suitable for comprehensive evaluationof Lentinula edodes varieties.Based on the screening results ofbothanalyticalmethods，X15（DehaiNo.1），X12（808-2）andX20（Shenxiang215）exhibitedsuperiorcomprehensive traits and were recommended for local promotion and application.
