Primer and method for identifying purity of Chinese cabbage seeds for spring seedling

The invention discloses a primer and a method for identifying the purity of Chinese cabbage seeds for spring-fu seedlings, and belongs to the technical field of biology. Therefore, the problems of long period, large workload, great influence of environmental factors, great influence of experience factors and the like caused by identifying the purity of the Chinese cabbages by adopting a field direct observation method in the prior art are solved, so that the seed purity of the Chinese cabbage hybrid for the spring-fu seedling can be rapidly and accurately identified within 1-2 hours; the method has the advantages of rapidness, stability, no environmental influence and the like, is beneficial to efficient and accurate quality control of the Chinese cabbage seeds for spring-fu seedlings, and has a wide application prospect. 本发明公开了一种鉴定春福苗用大白菜种子纯度的引物及方法，属于生物技术领域，通过能够应用于春福苗用大白菜杂交种纯度鉴定的引物，从而克服了现有技术中采用田间直接观察法鉴定虫子纯度导致的周期长、工作量大、受环境因素影响大、经验因素影响大等的问题，从而能够在1-2小时内快速准确的鉴定出春福苗用大白菜杂交种的种子纯度，具有快速、稳定、不受环境影响等优点，有利于春福苗用大白菜种子高效准确的
