本試驗為期選育豐產、質優之鮮食用及食品加工用新品種，採用人工及多向雜交方法育種，並按實生系選拔之育種程序進行。本年度多向雜交共採收雜交種子約20 萬粒,人工雜交三組合共採收種子4,153 粒，實生系選拔得春夏作40 品系，秋裡作230 品系；在品系產量比較試驗方面，春夏作第一年組共選18 個優良品系，秋裡作第一年一組及第一年二組分別選出19 個及11 個優良品系，以進行第二年組之產量比較之試驗；在新品系試驗方面，秋裡作部份，供試7 品系試驗結果發現,供試品系中以CYY98-32、CYY98-59 及CYY98-60之塊根產量較佳。
The purpose of this breeding program were to develop new sweet potato varieties with high yield and good quality for table-use and processing-use, we adopted artificial cross and polycross to select new lines, the result are summarized as follow: a total of 204,153 hybrids seeds were obtained from polycross and artificial cross during Oct. 2016 to Feb.2017 through seedling selection, 40clones for spring planting and 230 clones for fall planting were selected from 10,000 and 80,000 hybrid seedling respectively. Among the entries in primary yield trials, 18clones and 30 clones were selected for the spring and fall planting, those lines are all superior to the check variety in root yield potential as well as taste and agronomic characters. Among the entries in advanced yield trial, 4 clones for the spring planting and 18 clones for the fall planting were selected for high fresh root yield potential and good quality, 7 newly developed clones of yield trial were conducted in this fiscal year, In the fall planting of 2016 , CYY98-32、CYY98-59 and CYY98-60 were higher average fresh root yield than other tested clones.
