【摘要】 应用灰色关联分析对肺形侧耳种质资源进行了多性状的综合评价分析。通过构造参考菌株,对农艺性状值进行标准化变换,根据不同性状的相对重要性赋予不同权重,计算肺形侧耳菌株灰色关联度并排序。结果表明:菌株P5的综合性状最好（r′₅=0.6969）,菌株P16的综合性状较差(r′₁₆=0.5114)。依据肺形侧耳各菌株的灰色关联度排序所进行的综台评价分析结果与各菌株的栽培实际表现是一致的。更多还原

【Abstract】 The comprehensive evaluation and analysis of the germplasm resources of Pleurotus pulmonarius was carried out by grey relational analysis. The gray relational grade of Pleurotus pulmonarius strains were calculated and sorted by constructing the reference strain, transforming the characteristic values, and attaching different weights to the relative importance of different traits. The results indicated that the strain P5 had the best comprehensive traits（r′₅=0.6969）, while the strain P16 had the poorest comprehensive traits(r′₁₆=0.5114). The results of comprehensive evaluation by the gray relational grade were the same and coincided with the actual performances of the strains.更多还原
