摘　　要：对12个菠菜品种的生长性状、产量和品质指标进行调查和测定,采用主成分分析和聚类分析进行数据处理,筛选适宜崇明岛有机栽培的优质菠菜品种。结果表明,12个菠菜品种在生长性状、产量和品质等方面差异显著。在有机栽培模式下,综合质量表现最好的菠菜品种是金世纪和圆叶菠菜,其次是1518和哈里姆时代。其中,圆叶菠菜的单株鲜重和干重最大,分别为15.27g和2.24g;哈里姆时代的可溶性糖含量最高,达11.70%;金申小菠菜的硝态氮和草酸含量最高,分别达到了482.82μg/g和25.16mg/g,不适宜有机栽培。By principal component analysis and cluster analysis,growth potential,yield and quality of twelve spinach cultivars were analyzed for the purpose of selecting fine spinach cultivars for organic cultivation in Chongming Island.The results showed that there existed significant differences among different spinach cultivars in growth potential,yield and quality.In organic cultivation,the performances of＂Jinshiji＂and＂Yuanye＂were the best among all the cultivars.＂1518＂and ＂Halimushidai＂were better than the others.The fresh weight and dry weight of＂Yuanye＂were better than the other cultivars.Its fresh weight was up to 15.27 g and dry weight was up to 2.24 g.＂Jinshen＂was not suitable for organic cultivation because of its high content of nitrate nitrogen（482.82μg/g）and oxalic acid（25.16mg/g）.
