摘要：

With an F 2 population from the cross of two cucumber inbred lines, S06 and S52, sequence-related amplified polymorphism (SRAP) was used to construct a genetic linkage map in cucumber (Cucumis sativus L.). Sixty-four SRAP primer combinations generated 108 polymorphic bands in the F 2 population analysis. The average of polymorphic bands produced by one primer pair was 1.5, and the maximum was 5. Using Mapmaker 3.0, a linkage map was constructed, which consisted of 77 SRAP markers distributed in nine linkage groups (LOD≥3.0) and spanned 1114.2 cM with an average interval of 14.5 cM between markers. The gene for the first-flower-node trait, termed ffn, was mapped to linkage group Ⅸ, flanked by DC1EM5 and ME7EM2A at 10.3 cM and 12.1 cM distance, respectively.
