摘　　要：以高糖西瓜品系"花园母本"和低糖西瓜品系"LSW-177"为亲本材料配制杂交组合,测定各世代西瓜果实边缘及中心部分蔗糖、果糖及葡萄糖含量,利用主基因+多基因混合遗传模型多世代联合分析法,对获得六世代群体(P1,P2,F1,F2,BC1P1,BC1P2)的各可溶性糖含量在西瓜果实边缘和中心部位的遗传特点进行分析。结果表明,西瓜果实不同可溶性糖含量遗传模型不同,不同部位同一种糖含量遗传模型不一定相同。边缘蔗糖、中心蔗糖、边缘果糖、中心果糖、边缘葡萄糖和中心葡萄糖的遗传模型分别为D-1、E-4、C-0、C-0、D-2、E-3,均为主基因+多基因的数量性状遗传模型。With high sugar watermelon strain garden female parent and low sugar watermelon strain LSW-177 cross combinations, for material preparation measure the watermelon fruit edge and center part of sucrose, fructose and glucose levels, using main gene＋more hybrid genetic model generation joint analysis method, to obtain six generation group （P1, P2, F1, F2, BC1P1, BC1P2） of the soluble sugar content on the edge of the watermelon fruit and central parts of genetic characteristics. The results showed that the watermelon fruit different soluble sugar content in the genetic model, different parts of the same genetic model of soluble sugar content was not necessarily the same. The genetic models of edge of sucrose, middle of sucrose, edges of fructose, middle of fructose, edge of glucose, middle of glucose were D-1, E-4, C-0, C-0, D-2, E-3, respectively, al give priority to the number of gene＋more traits genetic model.
