食用甘藷品種選育

Abstract

利用嘉義農試分所所提供多向雜交甘藷種子培育實生苗篩選優良單株120 個，供作翌年甘藷觀察試驗材料。甘藷觀察試驗：選拔葉用甘藷品系1 個、食用甘藷品系18 個。甘藷新品系試驗第一年組試驗結果比對照種桃園一號及台農66 號產量高品系有3 個。大園試區第二年組試驗結果比對照種桃園一號產量高品系有1 個，比對照種台農66 號產量高品系有2 個。本場試區第二年組試驗結果比對照種桃園一號及台農66 號產量高品系有3 個。葉菜甘藷試驗結果參試3 個品系先端芽梢產量均低於對照種桃園二號。 The purposes of the breeding were to develop new tuber and leafy sweet potato varieties with high yield and good quality. The results of 2004 were summaried as follows :, 120 superior clones were selected from 15,000 seedlings. One clone for leafy use and 18 clones for tuber use were selected in the observation trial. In the first-year trial, three clones were higher yield than two checks, Taoyuan No. 1 and Tainung No. 66. In the second-year yield trial, 2 clones at Dayuan site and 3 clones at Taoyuan DARES were higher yield than the checks . In the leafy sweet potato yield trial, All testing clones were lower yield than the checks.
