Abstract: Molecular identification of 12 hybrid clones were carried out using primer combinations of EcoR I + 2 / Mse I + 3 by adopting AFLP marker technology. The results were as followeds: 10 primer combinations with more amplification bands were selected from 32 primer combinations, the total number of bands were between 7 and 52, number of polymorphism bands were from 2 to 28, polymorphism level of those primer combinations were from 23.5% to 41.6%, and lower level of polymorphism bands and proportion showed that the relationships of the samples were closed. The results of UPGMA cluster analysis and pedigree relations of 12 clones were the same, which indicated that clones with the same parents had higher genetic similarity coefficient. The fingerprinting map of 12 hybrid clones were draw using 9 polymorphism bands from 6 primer combinations, which would provide bases of identification and protection for hybrid clones.
