摘要 以复等位基因遗传的小白菜核基因雄性不育系00S107为不育源，采用杂交和连续回交方法，向青梗菜自交系CA123中转育核
不育基因，育成了性状与CA123相近、不育株率和不育度均为100 %的青梗菜核基因雄性不育系GMS001。用该不育系配成的杂交组合
GMS001×D3整齐一致，园艺学性状优异，产量显著高于对照品种华王。

| 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. |
