用可溶性固形物含量高、薄皮、感枯萎病的栽培西瓜自交系（Citrulluslanatus var. lanatus）97103和可溶性固形物含量低、皮厚、抗病的野生西瓜种质（Citrullus lanatus var. citroides）PI296341杂交所得F2的118个单株为作图群体，通过构建分子连锁图谱，对西瓜主要果实性状可溶性固形物含量、果皮硬度、果皮厚度、单果重、种子千粒重进行区间作图，定位了影响可溶性固形物含量的4个QTL、影响果皮硬度的5个QTL、影响果皮厚度的2个QTL、影响单果重的3个QTL、影响种子千粒重的6个QTL。此外，估算了每个QTL的贡献率、加性效应与显性效应。为开展西瓜果实性状改良分子标记辅助选择提供了理论基础。

In this study, we mapped and characterized quantitative trait loci (QTL) affecting watermelon fruit traits. A total of 118 F2 progenies derived from the cross 97103 (which is a cultivar with higher total soluble solids concentration, thin rind, susceptible to Fusarium wilt disease)×PI296341(which is a wild germplasm with lower total soluble solids concentration, thick rind, resistant to Fusarium wilt disease) were used to construct a 96-markers map in watermelon. By using interval mapping 4 QTLs for total soluble solids concentration, 5 QTLs for hardness of rind, 2 QTLs for thickness of rind, 3 QTLs for weight of simple fruit, and 6 QTLs for weight of one thousand grain seeds were identified. In addition, the explained variations, additive effects and dominance effects for all detected QTLs were analyzed.
