利用31个10bp随机引物对来自我国新疆和中东地区的11份旱麦草属种质资源的材料以及两个普通小麦亲本和1个普通与东方旱麦草的远缘杂种后代进行了RAPD分析。对扩增形成的321条谱带进行的研究发现，该属植物在新疆地区具有较丰富的遗传多样性，同时还将1个根据形态性状定名为光穗旱麦草的样品修正为东方旱麦草。研究还揭示出旱麦草属与普通小麦之间有明显的遗传分化，并发现四倍体光穗旱麦草的两个基因组分别来自二倍...
利用RAPD和RFLP分子标记技术对甘蓝型杂交油菜亲本遗传多样性的分析结果表明:(1)20个亲本间具有丰富的遗传多样性,40个引物扩增出277条多态性带,其中21条带为10个亲本所特有,12个探针得到了117条多态性杂交带,其中7条带为5个亲本所特有;(2)不育系与恢复系之间的遗传差异大于不育系内和恢复系内的遗传差异;(3)依RAPDs与RFLPs估计的亲本遗传多样性存在有一定的差异,这种差异由估...
