近年来，种子生化鉴定技术的应用对种子纯度检验的准确、快速和实用起了很大推动作用，但生理生化指标（如同工酶等）存在组织特异性和可利用位点有限，针对性强等限制因素。笔者对AFLP标记技术在大白菜种子真实性及品种纯度鉴定中的应用效果进行了探讨，以期建立一种稳定、快 In recent years, the application of seed biochemical identification technology has played a very important role in the accurate, rapid and practical testing of seed purity. However, the physiological and biochemical indexes (such as isozymes) have tissue specificity and limited available sites, Other constraints. The author of the AFLP marker technology in the authenticity of Chinese cabbage and species purity identification of the application of the effect were discussed in order to establish a stable, fast
