Abstract
A multiple allele inherited genetic male sterile line'00S107'was used as a source of male sterility in pakchoi.Methods of crossing and backcrossing were applied to transfer the male sterility to a male fertile line'CA123'.A new genetic male sterile line'GMS001'with 100 % of male sterile plants was obtained.'GMS001'was similar to'CA123'in horticultural characters.An excellent hybridized combination'GMS001×D3'was developed,which is uniform and superior to'Huawang'in yield.
