新修訂之文心蘭品種試驗檢定方法及品種性狀表

Amendment of Test Guidelines of the New Cultivars for Oncidium

摘要


文心蘭為臺灣重要外銷切花作物,為提升臺灣文心蘭品種競爭優勢,須訂定適宜的品種性狀表以因應未來新品種保護。可區別性(distinctness)、一致性(uniformity)和穩定性(stability)(簡稱DUS)是新品種保護之實質檢定要項,也是新品種保護的技術基礎。文心蘭試驗檢定方法及品種性狀表修訂,主要參考國內舊有之文心蘭品種試驗檢定方法及品種性狀表、國際植物新品種保護聯盟(International Union for the Protection of New Varieties of Plants, UPOV)之文心蘭檢定準則及相關技術文件。根據所收集之文心蘭品種及文心蘭品種檢定資料庫進行各種外表性狀表現之觀測,確立了101個性狀,其中必測性狀50項,一般性狀51項,同時確立各項性狀的分級註記及判定方式,以進行臺灣文心蘭新品種檢定作業之依據。
