中文摘要 | 藉由臺灣假山藥薯種原8 個質量性狀及9 個數量性狀調查,以評估其種原遺傳變異。調查結果,8 個質量性狀中以莖蔓顏色及芽色性狀頻度分佈較均勻,可供遺傳變異評估及品種鑑定參考,輔以9 個數量性狀,以增加種原評估或鑑定效果,9 個數量性狀以葉柄長度、葉中部寬度及節間長度等3 個性狀適合作為辨識種原指標。以群聚分析評估假山藥薯種原植株外表性狀遺傳歧異性,結果顯示地區族群相互重疊。本研究對臺灣假山藥薯種原植株性狀進行調查,並建立其種原蒐集、評估及利用上重要資訊。 |
英文摘要 | By eight qualitative and nine quantitative traits investigated to assess its genetic variation of D. persimilis Prain & Burkill in Taiwan.According to the distribution frequency, the qualitative traits of stem color and bud color were in uniform. These traits are suitable for the assessment of genetic variation and species identification. The quantitative traits of petiole length, medial leaf width and internode length, could be used as important indicators for species identification. Based on plant traits, the cluster analysis showed the overlapping distribution in regions for D. persimilis .In this paper, studies of D. persimilis in Taiwan have been established, and such important information will be useful in germplasm collection, evaluation and application. |
