Abstract：In order to screen out high-yield and high-quality Lentinula edodes varieties suitable for planting in western Henan,11 major agronomic traits of 24 varieties were selected as evaluation indexes,and comprehensive evaluation was carried out by grey correlation degree and DTOPSIS.The results showed that the correlation between the ranking of grey correlation method and the ranking of yield was low(r=0.476),and the evaluation paid more attention to the balance of traits.In contrast,the ranking of DTOPSIS method was significantly correlated with the ranking of yield(r=0.941),which was closer to the breeding goal of high yield and high quality.Both methods could reflect the comprehensive performance of Lentinula edodes varieties to a certain extent.The maximum difference rate of Ci value of DTOPSIS method was 56.37％,which was higher than the maximum difference rate of Gi value of grey correlation method(24.17％),indicating that the DTOPSIS method better highlight the differences and comparative advantages among varieties.Therefore,the DTOPSIS method is more suitable for comprehensive evaluation of Lentinula edodes varieties.Based on the screening re-sults of both analytical methods,X15(Dehai No.1),X12(808-2)and X20(Shenxiang 215)exhibited superior comprehen-sive traits and were recommended for local promotion and application.
