The present invention relates to an excellent-quality chicken maternal strain, in particular to a method for the strain breeding of the dark-shank spotty plumage chicken with dwarf gene, which belongs to the technical field of the dark-shank spotty plumage chicken with dwarf gene. The breeding procedures of the present invention are (1) selecting a cock of Chongren chicken and a hen having the dark-shank partridge in the grandparent hen group of the dwarf yellow-feather chicken as the breeding materials and selecting a normal-shaped cock having the dark-shank partridge character in the F1 generation after the hybridization of the cock and the hen; (2) Selecting the dark-shank partridge normal-shaped cock to be mated with the hen of the dark-shank partridge dwarf yellow-feather chicken and selecting the dark-shank partridge dwarf cock and the dark-shank partridge dwarf hen in the F2 generation; (3) cross-breeding and locking the selected dark-shank partridge dwarf cock and the dark-shank partridge dwarf hen so as to get the present invention after the breeding from generation to generation. Since the body of the maternal-strain chicken is short cultivated through the present invention, the chicken has the outstanding advantages of precocious puberty, high-yield of eggs and less feed consumption and cultivated space saving, which greatly reduces the production cost of the commodity generation chicken and improves the comprehensive benefit of the cultivation.
