摘要
以复等位基因遗传的白菜核基因雄性不育系00S107为不育源,采用连续回交转育同时测交筛选基因型的方法,向紫菜薹自交系XA500中转育核不育基因,育成了园艺学性状与XA500相近,不育株率和不育度均达到100%的紫菜薹雄性不育系GMS500。用该不育系配成的杂交组合整齐一致,园艺学性状优异,单位面积产量显著高于对照品种‘紫婷11号’。
In order to solve the problems in the transfer and utilization of genic male sterile line in purple stalk Chinese cabbage,'00S107'which is a multiple allele inherited genetic male sterile line was used as a source of male sterility in Brassica campestris L.ssp.chinensis var.purpurca Hort.Methods of crossing and backcrossing were applied to transfer the male sterility to a male fertile line'XA500'.A new genetic male sterile line'GMS500'with 100% of male sterile plants was obtained,which was similar to 'XA500'in horticultural characteristics.An excellent hybridized combination was developed,which is uniform and superior to'Ziting 11'in yield.
