Abstract：To rapidly detect the purity of hybrid seeds from frozen damaged plots in the overwintering seed production base of Xinxiangxiaobao 23,ensure that the quality of seeds entering the market meets standards,protect consumers rights,and improve the efficiency of hybrid seed screening,specific primers were selected from 12 pairs of InDel primers for Chinese cabbage to distinguish Xinxiangxiaobao 23 and its parents,and seed identification was carried out.The results showed that three pairs of primers exhibited co-dominance,among which one pair could effectively distinguish Xinxiangxiaobao 23 from the other three similar varieties.This primer was verified in 108 hybrid progenies,and the purity identification result was 93.5％,which was basically consistent with the field identification result.In conclusion,the InDel marker BrID90105 selected in this study can be used for rapid identification of seed purity in Xinxiangxiaobao 23,promoting the healthy development of the seed industry.
