Phenotypic genetic diversity of a core collection of Ziziphus jujuba and correlation analysis of dehiscent characters

  • 摘要: 为了明确枣核心种质的遗传多样性和变异特点,了解枣裂果性状与果实(核)性状的相关性,提高枣种质的利用效率,本研究对枣核心种质的果实、果核和裂果等相关的9个重要表型性状指标进行了测定和统计分析。结果显示:1)核心种质资源具有较丰富的表型变异,9个表型性状的变异系数均达20%以上,平均变异系数为39.00%;其Shannon-Wiener's多样性指数为1.49~1.93,平均多样性指数为1.77。2)相关性分析结果显示, 9个表型性状指标之间存在不同程度的相关性,多个果实(核)表型性状之间均存在显著相关性(正相关或负相关),果实横径与裂果率达到显著的正相关,果形指数与裂果指数之间达到显著的负相关。果核性状与裂果性状均无显著相关性,裂果率和裂果指数之间达到了极显著的正相关。3)利用主成分分析方法确定了4个主成分,累计贡献率可达94.79%,即这4个主成分保存了原始性状94.79%的遗传信息。9个表型中果实纵径、裂果指数、果核指数和果形指数是造成枣核心种质表型多样性的主要因素。
