摘　　要：以杧果‘金煌’为母本、‘爱文’为父本的杂交F1代95株群体及亲本为材料,对果实糖酸品质等性状进行了描述性统计分析、相关性分析、方差分析和广义遗传力分析等。结果表明:杧果果实主要含3种单糖——葡萄糖、果糖、蔗糖和6种单酸——苹果酸、柠檬酸、抗坏血酸、琥珀酸、α–酮戊二酸、乳酸。糖、酸等果实品质性状在杂交群体中呈正态分布或者近似正态分布;果糖含量分别与葡萄糖和蔗糖含量极显著正相关,柠檬酸含量与可滴定酸、α–酮戊二酸含量呈显著正相关,苹果酸含量与琥珀酸、抗坏血酸含量呈显著正相关。葡萄糖含量的平均值低于中亲值,介于双亲之间,既没有中亲优势也没有超亲优势;果糖和蔗糖含量表现出中亲优势,具有明显的杂种优势;单酸中,除了苹果酸和琥珀酸具有中亲和超亲优势以外,其余大部分的单酸既没有中亲优势也没有超亲优势。To analyze the genetic variation of sugar and acid contents in mango F1 population in order to provide a basis for selecting parents in cross breeding of mango.A hybrid population of 95 F1 plants with‘Jinhuang’as the female parent and‘Irwin’as the male parent was constructed.Descriptive statistical analysis,correlation analysis,analysis of variance and broad-sense heritability analysis were carried out for the sugar and acid quality traits of mango fruits.Current results indicated that the major individual sugars were glucose,fructose and sucrose;the main organic acids were malic acid,citric acid,ascorbic acid,lactic acid,succinic acid andα-ketoglutaric acid in mango fruits.These fruit quality traits such as individual sugar and organic acid showed normally or nearly normally distribution in hybrid population;fructose was highly significantly correlated with glucose and sucrose;citric acid was significantly positively correlated withα-ketoglutaric acidand titratable acid,malic acid was significantly positively correlated with succinic acid and ascorbic acid;fructose and sucrose showed a mid-parental heterosis;and most of organic acids showed neither a mid-parental nor a super-parental heterosis.
