Abstract Taking Chinese cabbage‘Niupai No.19’hybrid seeds as test material，this paper constructed a rapid molecular marker testing technique system used before Chinese cabbage hybrid seeds being stored in genebank by every link，including seed pr-treating，DNA easy isolation and quality detection，primers screening，etc.and compared it with the result from fields identification．The results showed the identification results by molecular marker from the system were basically consistent with that by field planting．The purity of hybrids was about 97%．Taking the single plant seedlings treated for 72 hours to rapidly etract DNA by 2-step DNA isolation were sufficient for completely satisfying the needs of molecular marker detection．
