摘要:
探讨云南地区砂梨种质资源的遗传背景,选用4对呈现多态性的叶绿体引物,对19个原产于云南省的砂梨品种和3个对照品种的trnL-trnF、rbcL、trnS-psbC区域进行扩增。结果表明:4对引物的扩增结果合并后得到长度为3 831 bp叶绿体基因片段,含有4个单倍型(H1~H4)、14个多态性位点,其中单一突变位点11个,简约信息性位点3个,插入/缺失(InDel)1个。19份砂梨种质的单倍型(基因)多样性(Hd)、核苷酸多样性(Pi)分别为0.602、0.000 38。合并后的片段经Tajimas D检验其D值基本未达显著水平,遵循中性模型。4个叶绿体单倍型的中介网络显示:单倍型H1与H2、H3的亲缘关系较近,而H4则与上述3个单倍型的亲缘关系较远。经叶绿体单倍型分析可知,云南砂梨地方品种的遗传多样性较为丰富。
