Abstract:
     The invention relates to a method for breeding the cytoplasm male sterility ternary rape. The invention takes recessive nuclear sterile plant as female parent, cytoplasm male sterility retention line, recovery line or hybrid as male parent for crossing, transports the cytoplasm male sterile gene or recovery gene to next generation by using the nuclear sterile character of recessive nuclear sterile plant, breeds retention line or recovery line with these target gene through autocopulation in following generations, and breeds sterile line simultaneously. The invention is characterized by the simple breeding method, obvious selected field, shortened breeding cycle by 2-3 generations. The invention makes full use of the nuclear sterile breeding product to provide a new source for cytoplasm male sterility ternary. The got recovery line, sterile line or recovery line are complete cytoplasm male sterility ternary with no nuclear male sterile gene.
