摘　　要：以低糖西瓜(籽瓜)与高糖西瓜杂交的F1代、F2代、F1代与双亲的回交代及其亲本为材料,在西瓜果实成熟期测定果实可溶性固形物、可溶性糖(蔗糖、葡萄糖和果糖)含量,分析研究果实葡萄糖、果糖、蔗糖含量的遗传规律.结果表明:西瓜果实葡萄糖、果糖含量属数量性状遗传,即多基因决定的性状,蔗糖含量可能由一对显性或不完全显性的主效基因决定着低水平的含量,还有数对基因决定着高蔗糖或低蔗糖的含量.Parents and progeny were P1 （edible seed watermelon）and P2 （high sugar watermelon for flesh）,progeny included F1 ,F2 and F1 back cross with parents were used to study on genetic characteristics of sugar content watermelon fruit （sucrose,glucose and fructose）.The results indicated that fructose and glucose content were quantitative traits controlled by multiple genes.One pair of dominant or incomplete dominant maj or genes determined low level of sucrose content.There were several pairs of genes deter-mined a high or a low level of sucrose content.
