Summary: | The invention discloses a recurrent breeding method of a cotton variety, and relates to the technical field of the breeding of cotton varieties. The recurrent breeding method of the cotton variety comprises the following steps of selecting multiple selfing-line materials, which are relatively broad in hereditary basis and high in general combining ability and belong to the same class group, as a base population to carry out recurrent selection; establishing a hybrid group on the basis of hybridizing the selfing-line materials with multiple cotton strains or coeno-species materials in a batch manner, wherein the cotton strains and the coeno-species materials belong to different types, have target traits, can normally and naturally reproduce and further do not contain sterile genes; obtaining an isolate recombination group and a stable selection group from the hybrid group; and forming one cycle by the four population groups of the base population, the hybrid group, the isolate recombination group and the stabl |
