Breeding and Utilization of Cabbage Cytoplasmic Male Sterile Lines

Through field investigation, seven broccoli cytoplasmic male sterile materials were selected out of 19 crossbreed materials of Japanese broccoli. Six cabbage cytoplasmic male sterile lines were obtained by crossing the male sterile materials with cabbage inbred lines as recurrent parents; the sterile lines showed excellent general characteristics with high combining ability, both of sterile plant rates and sterility reached 100%. Five excellent hybridized combinations were obtained by crossing with the male sterile lines. Xiahua No.2 is a variety that developed through the field screening.
