Abstract: Fuzzy mathematics and cluster analysis were used for comprehensive quality evaluation of 12 bioeconomic indicators of 23 common cultivated species of Pleurotus ostreatus in 2019 in Henan Province.The results showed that coefficients of variation of mycelia resistance and external quality-related indexes of fruiting body were larger,while coefficients of variation of yield and internal quality-related indexes were lower.The results of fuzzy mathematics evaluation and cluster analysis were consistent. The species of Heiping 17-1,Huimei 2,Xin 831,Nongping 4,Heikang 650,Heifeng,and Tianda 300 with superior quality were clustered into group Ⅰ. The species of Bianyixiafu,Y9H15,Zaoqiu 4508,Nongyou 3,Y6P3,Heiping 16-1,Pingza A,5506,and Huiping 1 with average quality were clustered into group Ⅱ.The species of Nongping 1,Jiangdu 71,Xuemei,Xiaobaiping,Nairewang,Suyin 6,and Zhongshu 10 with the worst quality were clustered into group Ⅲ.Fuzzy mathematics combined with cluster analysis could provide a comprehensive and objective evaluation system for determining the quality of Pleurotus ostreatus.

摘要： 2019年对河南省23个平菇品种的12个生物经济学指标进行观察检测，并运用模糊数学和聚类分析评价不同平菇品种的综合品质。结果表明，不同品种间菌丝抗逆性和子实体外在品质相关指标的变异系数较大，而产量和内在品质相关指标的变异系数较小。模糊数学评价与聚类分析结果较为一致：品质优良的黑平17-1、灰美2号、新831、农平4号、黑抗650、黑丰、天达300聚为Ⅰ类，品质中等的变异夏福、Y9H15、早秋4508、农友3号、Y6P3、黑平16-1、平杂A、5506、灰平1号聚为Ⅱ类，品质差的农平1号、江都71、雪美、小白平、耐热王、苏引6号、中蔬10号聚为Ⅲ类。模糊数学评价方法结合聚类分析可给予平菇综合品质较全面、客观的评价。
