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.
