The invention discloses a breeding method of albino paramisgurnus dabryanus capable of being inherited stably. The method comprises the steps as follows: a TYR (tyrosinase) gene target site is designed on a TYR gene sequence of paramisgurnus dabryanus, then an upstream primer and a downstream primer matched with the upstream primer are designed, PCR (polymerase chain reaction) amplification is performed with framework plasmid as a template, in-vitro transcription and purification are performed, and gRNA is obtained; Cas9 mRNA is obtained from linear Cas9 plasmid as a template after in-vitro transcription and purification; micro-injection is performed on fertilized eggs of the paramisgurnus dabryanus, the fertilized eggs are then incubated, gene knock-out fish is subjected to hybridization, and the albino paramisgurnus dabryanus capable of being inherited stably is obtained.
