| 摘 要： | 藕莲是莲（Nelumbo nucifera Gaertn.ssp.nucifera）的3种类型之一,在我国作为水生蔬菜栽培的历史愈两千年。对国家种质资源圃中来自17个省和直辖市的68份藕莲资源的19个形态和农艺性状进行了观察,并对其遗传变异进行了分析。结果发现整藕重与主藕重、主藕长和第三节粗成极显著正相关。通径分析结果表明主藕重对整藕重的正向效应最高（0.982）。主成分分析结果显示前4个成分占总变异的77.33%。结果还显示对整藕重负效应最高的是主藕重/整藕重（-0.296）。聚类分析发现所有藕莲资源可分为5组。

| Abstract: | Rhizome lotus (Nelumbo nucifera Gaertn.ssp.nucifera) has been cultivated for more than two thousand years as a food in China.The genetic variability in sixty-eight rhizome lotus germplasms from different regions of China,were evaluated using nineteen morphological characteristics.The associations of whole rhizome weight (TW) with main stem weight (MW),main stem length (ML),and width of the main stem section between the third and fourth knot (RW) were positive and highly significant.The path analysis reveale... |
