摘要
利用UPGMA法对 199个陕西省白菜型油菜品种的 15个性状进行形态标记聚类分析 ,并将淘汰后保留的 2 9个品种作RAPD标记分析和聚类分析。通过比较RAPD标记和形态标记差异 ,以 2 8个品种初步建立了陕西省白菜型油菜核心种质。研究结果表明 ,形态标记与分子标记所揭示的遗传差异并不总是一致的 。
The UPGMA method was appled to cluster and analyze 15 characters of 199 landraces of B.campestris germplasm from Shanxi province with morphological markers. The left 29 varieties through eliminating unwanted entries were analyzed by UPGMA and RAPD markers. The dendrograms of B.campestris by RAPD and morphological markers were compared, and the core germplasm including 28 varieties of B.campestris from Shanxi province was preliminarily assembled. The results showed that genetic variation revealed by morphological markers was not always consistent with revealed by RAPD markers to a certain degree. It was an effective method to develop a core collection of the crop by RAPD markers and morphological markers.
