Abstract: For ensuring the seed genetic quality, increasing the efficiency of application of the variety identification and seed genetic purity on cucumber hybrid seed, alternative 63 pairs of SSR primers have been applied in the screening the molecular markers on the cucumber Jingyan Lvfeicui and their parents. The results showed that 16 pairs of primers complementary to appear polymorphic bands between the parents, clear and stabilized, performing codominance, highly specificity, among hybrids, which can be used to distinct its parents and other varieties. The core SSR primers of Jingyan Lvfeicui were composed mainly of these 16 pairs of primers, formed the SSR fingerprint of Jingyan Lvfeicui, which provided technological information for seeds purity, authenticity of hybrid and parents purifying. Among them, the bands amplified by 10 pairs of primers were high distinguishable, the particularity was strong, as well as the characteristics of clear bands and the result agreed with field test.
