[目的]解释甜瓜属植物种间杂交特性。[方法]以150个薄皮甜瓜品种为母本,分别与甜瓜野生近缘种角瓜（Cucumismetuliferus）和西印度瓜（Cucumisanguria）进行种间杂交。[结果]以编号V2和V129的薄皮甜瓜与角瓜和西印度瓜杂交后能够坐果,但与角瓜杂交后种子败育,而与西印度瓜杂交后仅在果实底部有少量可育种子。采用SRAP分子标记技术对西印度瓜×V129杂交后代分析表明,1对引物（E14/M2）扩增出少量父本（西印度瓜）特征带,表明西印度瓜与V129已经在DNA分子水平上发生了交换。[结论]该研究为深入揭示该属植物中间杂交提供了资料。

To understand the inter-hybridization between Cucumis ssp.plants,we used 150 melon varieties as female parents to cross with Cucumis metuliferus and Cucumis anguria.Only melon accessions V2 and V129 set fruits,but seeds from fruits V2（V129）×C.metuliferus were abortive.A few of seeds from the bottom of fruit V2（V129）×C.anguria were fertile.Sequence-related amplified polymorphism（SRAP）molecular markers were used to analyze the progenies of inter-specific hybridization between C.anguria and melon V129.One pair primer（E14/M2）was found effective in amplification on male parent characteristic bands from the hybrids,suggesting that some DNA exchange had happened between C.anguria and melon V129.This study provided data for analyzing the mechanism of inter-hybridization between Cucumis plants.
