Breeding method and application of recessive genic male sterility homozygous two-type line and temporary maintainer line of glossy leaves

The invention relates to a breeding method and application of a recessive genic male sterility homozygous two-type line and a temporary maintainer line of glossy leaves. The breeding method comprises the following steps: performing cross-fertilizing and bagging selfing with a sterile plant as female parent and the recessive glossy leaves as a male parent in a recessive genic male sterility homozygous two-type line 20118AB of cabbage type rape to obtain a sterile plant of the recessive glossy leaves; performing cross-fertilizing on the sterile plant of the glossy leaves and a fertile plant in 20118AB to breed a new homozygous two-type line, namely a genic male sterility homozygous two-type line of the recessive glossy leaves, and performing cross-fertilizing on the homozygous two-type line and the temporary maintainer line to obtain a new temporary maintainer line, namely the temporary maintainer line of the recessive glossy leaves; and producing a full male sterility line of the glossy leaves by adopting the
