中文摘要 | 藉由臺灣戟葉田薯種原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。結果顯示,8個質量性狀以老葉顏色、幼葉顏色、莖蔓顏色及芽色性狀頻度分布較均勻,可供遺傳變異評估及種原鑑定參考,輔以9個數量性狀,以增加種原評估或鑑定效果。9個數量性狀以葉中部寬度及葉長中寬比等2個性狀適合作為辨識種原重要指標。以群聚分析評估戟葉田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。本研究對臺灣戟葉田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. doryphora Hance in Taiwan. According to the distribution frequency, the qualitative traits of matured leaf color, young leaf color, 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 medial leaf width, the ratio of leaf length and medial width could be used as important indicators for species identification. Based on plant traits, the cluster analysis showed the overlapping distribution in regions for D. doryphora Hance. In this paper, studies of D. doryphora Hance in Taiwan have been established, and such important information will be useful in germplasm collection, evaluation and application. |
