This invention relates to a method for breeding dwarf and black-legged chickens and its application. The breeding method includes the following steps: breeding D, E, and C lines respectively, using D line as the first paternal line, E line as the terminal paternal line, and C line as the maternal line; hybridizing the first paternal line D line with the maternal line C line to obtain parent generation hens; and hybridizing the parent generation hens with the terminal paternal line E line to
breed dwarf and black-legged chickens. This invention introduces sex-linked dwarfism genes into the Iron-Leg Ma chicken
breed to
breed sex-linked dwarf Iron-Leg Ma chickens. Simultaneously, it pairs high-reproductive-performance recessive White Locker chickens with black-legged Ma chickens, resulting in commercial chickens suitable for markets in Southwest and Northern China, possessing characteristics such as black legs, dwarf legs,
white meat,
fast growth rate, and high feed conversion rate.
