摘　　要：以44份西瓜种质为试验材料,设置0(CK)和150 mmol·L^(-1)NaCl 2个处理水平,测定不同西瓜种质幼苗的15项指标。以15项指标的耐盐系数作为耐盐性评价依据,运用相关性分析、主成分分析、隶属函数值法、聚类分析等多元分析方法进行综合评价。通过主成分分析将15个单项指标转换为4个相互独立的综合指标,累计贡献率为71.10%;以耐盐系数为基础进行聚类分析,筛选出10个高度耐盐、21个中度耐盐、13个弱耐盐西瓜种质资源。采用隶属函数法进行综合评价,排名前5的种质分别是HY-91、DQ-308、W19-15、HY-73、W19-10,归为聚类分析中的第一类,属于强耐盐性品种。Fourty-four watermelon germplasms were used as experimental materials,and 0(CK)and 150 mmol·L^(-1) Na-Cl was used at two treatment levels,and 15 indexes of different watermelon germplasm seedlings were determined.The salt tolerance coefficient of 15 indicators was used as the basis for salt tolerance evaluation,and multivariate analysis methods such as correlation analysis,principal component analysis,membership function value method and cluster analysis were used for comprehensive evaluation.The 15 individual indicators were converted into 4 independent comprehensive indicators by principal component analysis,and the cumulative contribution rate was 71.10%.The cluster analysis was carried out on the basis of the salt tolerance coefficient,and 10 highly salt-tolerant,21 moderately salt-tolerant and 13 weakly salt-tolerant watermelon germplasm resources were screened out according to the size of the D value.The comprehensive salt tolerance evaluation value of each germplasm was obtained by the membership function value method,the top 5 were HY-91,DQ-308,W19-15,HY-73 andW19-10,belonging to highly salt-tolerant germplasm.
