摘要: 在已掌握甘蓝型油菜%萝卜附加系染色体构成, 并构建萝卜分子连锁图谱的基础上, 以甘蓝
型油菜—萝卜附加系为材料, 利用( dp) RAPD分子标记技术, 筛选附加系中外源萝卜9条染色体(A~ I)
的分子标记, 为进一步研究萝卜染色体与连锁群对应关系奠定基础。试验筛选了576个随机引物(组合) ,
有413个能从附加系中扩增出萝卜染色体的( dp ) RAPD标记, 平均有效引物(组合) 占71.7% , 其中
RAPD反应有效引物率67.7% , dpRAPD 反应有效引物率73.2%。试验共得到899 个萝卜染色体( dp )
RAPD标记, 包括354个RAPD标记和545个dpRAPD标记, 覆盖萝卜整个基因组的全部9条染色体, 不同
染色体的标记数目变化范围在41~160, 其中最多的是染色体C, 最少的是染色体I。

Abstract: In previous researches, a series of rape2radish addition lines with known additional radish
chromosomes and a linkage map of oil radish consisting of 9 group s have been developed. To study the assign
ment between the linkage group s and the chromosomes of radish, this work was carried out to screen radish
chromosome-specific molecularmarkers from rape-radish addition lines bymeans of ( dp) RAPD technology so
as to integrate radish chromosome markers into the linkage groups in further research. 576 decamer primers
and pair-primers were tested to identify molecularmarkers for radish chromosomes (A - I). As a result, 413
primers and pair-primerswere effectual to amp lify radish chromosome2specific ( dp) RAPD markers, the effec
tual primers (pair-primers) occup ied averagely 71.7%. This ratio in p rotocol of RAPD was 67.7% , and that
in dpRAPD was 73.2%. Altogether 899 ( dp) RAPD markers for all 9 chromosomes of radish were obtained,
including 354 RAPD markers and 545 dpRAPD markers. The number of markers for individual chromosome
varied from 41 for chromosome I to 160 for chromosome C.
