Abstract:

The research methods and recent progress of domestication breeding (systematic breeding), crossbreeding including single-single hybridization, single-double hybridization, multi-spore hybridization (self-crossing) and protoplast fusion breeding, mutation breeding and molecular breeding technologies of Auricularia cornea in China were summarized. Some newly bred cultivars and their characteristics were introduced, and the research methods for the propagation of A. cornea in solid and liquid strains were summed up. Molecular marker-assisted breeding, genome editing, genomic selection and other molecular breeding methods are proposed for future crossbreeding of A. cornea in China. The high-efficiency breeding technology will be rapidly applied, the commercial breeding of A. cornea will be actively promoted, and the ‘breeding- propagation- promotion’ system will be gradually improved.

Key words: Auricularia cornea, selective breeding, crossbreeding, mutation breeding, molecular breeding, spawn propagation
