Abstract: The paternalparents of 1 728 open-pollinated seedlings of‘Dongzao’(Ziziphus jujuba Mill.)and 530 open-pollinated seedlings of‘Lingbao Dazao’were identified with SSR technique. Eight primer pairs were selected from 376 primer pairs,which amplified distinct,polymorphic segments and showed high differential rate. Twelve candidate parents were analyzed by capillary electrophoresis using fluorescent M13 multi-state detection method. Totally,45 polymorphic alleles were revealed,with an average of 5.625 for each primer pairs. Polymorphism information content values for the primer pairs ranged from 0.58 to 0.86,with an average of 0.71. Using software Cervus3.0,399 hybrids from‘Dongzao’בMuzao’were identified,and 390 from‘Dongzao’בXiaoyazao’,357 from‘Dongzao’בYingshanhong’,204 from ‘Lingbao Dazao’בZiyuanzao(Zizao)’,126 from‘Lingbao Dazao’בShibingzao’were also identified.

Key words: jujube, SSR, paternal parent analysis, capillary electrophoresis
