Abstract:

30 wild Auricularia auricula strains were collected from Heilongjiang Province and analyzed by using sequence-related amplified polymorphism (SRAP) markers. 8 SRAP primer combinations amplified 157 fragments of which 122 (77.71%) were polymorphic. Phylogenetic tree was constructed by using the Unweighted Pair-group Method with Arithmetic Averages (UPGMA) method. 30 strains distributed into six groups. The clustering analysis showed that there was a high level of genetic diversity among A. Auricula. This study will provide good reference for parent selection in further cross-breeding programs.
