| 摘 要： | 对11份野菊材料分别用ISSR分子标记和形态学特征进行了遗传分析。用13个引物共得到176个位点,其中166个为多态性位点,多态性比率(PPB)高达94.32%;结果表明:2种分类方法得到的结果不甚一致。说明了野菊是一个多型性的种,在形态上表现出体态、叶型、叶序、伞房花序式样以及茎叶毛被性等诸特征上的极大的多样性。从ISSR标记分析,湖北神农架野菊和安徽天堂寨野菊之间的遗传系数最大,为0.727;安徽天柱山野菊和南京野菊之间的遗传系数最小,为0.591。

| Abstract: | The genetic relationship of 11 Chrysanthemum indicum was analyzed with ISSR markers and morphological traits.With 13 ISSR primers,166 polymorphic loci were detected out of 176 loci in total.Results obtained from ISSR and morphological traits indicated that they exhibit the different tendency.It indicated that Chrysanthemum indicum has many different surfaces.It in difference of posture,phyllotaxy,inflorescence and so on.Cluster analysis showed that the GS value of Hubei Shen nongjia was 0.727.Anhui Tiantang... |
