摘要
以大葱(Allium fistulosum L.)雄性不育系和保持系为试材,开发了一个能够鉴别细胞质雄性不育类型的SCAR标记。此标记在大葱雄性不育系(S型细胞质)中扩增出1条607bp片段,而在保持系(N型细胞质)中没有扩增出此片段,将此片段命名为S607。对5组不同遗传背景的不育系和相应保持系,以及4份杂交组合进行验证,SCAR标记S607鉴定结果与实际细胞质类型完全相符。
Cytoplasmic genetic male-sterility（CMS）is used to produce hybrid bunching onion （Allium fistulosum L.）seeds worldwide. In this paper,we developed one SCAR marker using male sterile lin（e980238A）and maintainer line（980238B）as sterile and fertile gene pool for the target band screening. This marker was 607 bp in size and designated as S607 which was specifically amplified in the male sterile line,and it could distinguish two cytoplasm types CMS-S（Sterile type）and CMS-N（Normal type）. The SCAR marker was verified in five male sterile lines,five maintainer lines,and four cross combinations, all of these valuations were in accord with their cytoplasmic type（S or N）. The result of this study indicates that the SCAR markers of S607 will greatly contribute to establish a molecular marker assisted breeding program in bunching onion.
