A total of 172 SSR markers, according to the information of available melon and cucumber genetic maps (Diaz et al., 2011), were screened in one DNA bulk which was prepared from 5 accessions with distant genetic relationship. Thirty-six SSR markers were chosen based on their polymorphism, repeatability, and unambiguous polymerase chain reaction (PCR) products. The sequences of these SSR markers are listed inTable 1. PCR amplification was conducted in a Thermal Cycler (BIO-RAD C1000™) with the following protocol: 94 °C for 3min; 35 cycles of 94 °C for 30 s, 55 °C for 30 s, 72 °C for 30 s; and 72 °C 10 min. Finally, the amplified fragments were analyzed by electrophoresis on 32 cm × 38 cm × 0.04 cm 6% denaturing polyacrylamide gels.
