杂交育种

Although the conservative termed secondary homothallism inherit mode and absence of wild resources, the commercial strains encompass extremely limited genetic variation, in this paper we revealed some variations of phenotypic and genorypic characteristics among the tested strains in mycelium growth rate, field performance, esterase isozyme, soluble protein and AFLP fmgerprint.
