摘　　要：以36份芒果种质为试材,利用高效液相色谱技术,进行芒果果实含糖量(果糖、葡萄糖和蔗糖)的分析测定。结果表明,不同芒果种质间含糖量差异较大,Dashehari糖含量最高,达16.04%,‘林生芒’最低,仅为3.49%。不同种质这3种糖的比例有较大差异,根据单糖、双糖的比例,将芒果种质分为3个类型:蔗糖积累型,如‘海豹’、Lippens、‘金煌’、‘四季芒’等;己糖积累型如KRS、‘林生芒’和20001;中间类型如‘桂香’、‘黄象牙’、‘斯里兰卡811’、‘泰国504’、‘乳芒’、紫花。同时根据芒果果实含糖量,对36份芒果种质采用平均距离法进行聚类分析,第1类芒果种质包括:R2E2、‘海豹’、Bambaroo、‘金煌’、‘黄象牙’、‘乳芒’、‘泰国504’、Keitt、‘紫花’、‘桂香’、‘斯里兰卡811’、KRS共12个品种;第2类芒果种质包括:Ono、‘四季芒’、‘红象牙’、‘实选4’、Lippens、‘台农1号’、Mallika、‘台红’等21个品种;第3类包括Dashehari这个品种,第4类包括20001这个品种;第5类包括林生芒。The fruits of 36 mango germplasm were used as materials to study the sugar content（Fructose,glucose and sucrose）of mango pulp by using High Performance Liquid Chromatography（HPLC）technology.The results showed that there were significant differences among the total content of different mango germplasm,ranged from 16.04%（Dashehari）to 3.49%（M.Sylvalica）.There were also obvious differences on proportion of fructose,glucose and sucrose among different mango germplasm.They could be classed into 3 types based on their sugar composition：（1）Sucrose prevalent type,including＇Haibao＇,＇Lippens＇,＇Chun Hwang＇,and so on.（2）Monosacccharide prevalent type,including KRS,＇M.Sylvalica＇and 20001.（3）Intermediate type,including＇Guixiang＇,＇Yellow Ivovy＇,＇Sri LanKa811＇,＇Thailand 504＇,＇Rumang＇,＇Zihua＇.According to the sugar content of mango fruits,with the acid of average cluster analysis,36 mango germplasm were divided into 5 groups.The first group included 12 cultivars such as＇R2E2＇,＇Haibao＇,＇Bambaroo＇,＇Chun Hwang＇,＇Keitt＇,＇Thailand 504＇,＇KRS＇,et al..The second class included 21 cultivars such as＇Ono＇,＇Red Ivory＇,＇Lippens＇,＇Tainong No.1＇,＇Mallika＇et al..＇Dashehari＇,20001,and＇M.Sylvalica＇belonged to the other groups,respectively.
