Abstract: The paper aims to understand the genetic information of the introduced germplasm resources, promote efficient distinction and rational utilization. Population structure analysis and molecular ID construction of 96 coriander samples were studied using RAPD. 23 from 300 random primers showed high polymorphism, 34 polymorphic bands were detected, and the quantity of detected alleles of the 23 primers ranged from 2 to 10, at an average of 4.61. The difference of specialty indices among varieties was relatively large, which ranged from 69.964 to 208.694, at an average of 104.29. Based on the diversity analysis, the molecular identities of the 96 coriander varieties were constructed by 14 primers: S2025, S2007, S2020, S2029, S177, S183, S509, S169, S1260, S167, S45, S24, S43 and S29. They can differentiate the samples effectively.
