Abstract:

对小麦回交后代的蛋白质含量进行了分子标记辅助选择研究。先对2个与蛋白质含量相关的Xgwm570和E41M62-168标记进行验证,表明其与蛋白质含量密切相关。再通过表型选择、分子标记辅助选择(MASBC2)和不加选择(RNDBC2)产生的BC2中,蛋白质含量的平均值和群体中蛋白质含量高于16.5%的植株比例在PHEBC2和MASBC2之间没有显著差异,但均显著高于RNDBC2。对群体中的植株按两分子标记的类型分为A(2个位点)、B(1个位点)和C(无)3大类,蛋白质含量的平均值和植株中蛋白质含量高于16.5%的比例从高到低的排列顺序为:A类植株>B类植株>C类植株。由此看来,利用分子标记辅助选择来培育高蛋白质含量小麦是十分有效的方法。
