Abstract
1.超甜玉米：96 年春作完成春蜜81 個S5 世代之分離、夏蜜79 個S5 世代之分離、雙魚品種27 個S5 世代之分離、泰國TN103 品種81 個S4 世代之分離、彩珍分離至S4 世代計有134 個。進行測交種種子之生產，共獲得426 個單交組合。熱帶型間新品系產量比較試驗(A組)，有四個試驗產量表現與對照種相近，其去苞葉鮮果穗產量介於11.76~12.84kg/6.4m2。B組106 個測交種組合力檢定，根據鮮果穗產量、外表性狀、穿刺力、及甜度等綜合考量後，選留23 個組合表現較佳者。
2.黑糯：(1) 組合力檢定：從160 個組合經組合力檢定後，根據植株、果穗外觀、產量及初步品評後選留14 個新組合，去苞葉鮮穗重明顯的高於對照種的有7 個組合。(2) 區域試驗：完成春作三個地點之區域試驗，新品系以TAPH90-06 之產量表現較對照種黑美珍高產。提供黑糯台農5 號F1 種子給農民推廣試種10 公頃，農民對此品種食用品質反應極好，已完成品種轉移專屬授權審查，目前在公告授權中。
3.白糯玉米：完成WXPOP1~ WXPOP13 族群內薄皮自交系200 個 S5 世代之繁殖培育。同時完成220 個測交種種子之生產。從80 個組合經組合力檢定後，根據植株、果穗外觀、產量及初步品評後選留9 個新組合，P1-1 x P12-4 的去苞葉鮮穗重較對照種明顯增加；而與對照種無明顯差異的有7 個組合。
4.食用普通白玉米：完成三個地點之區域試驗，新品系以TAWH92-9 之產量表現較高。
1.Supersweet corn: Select for plant and ear type was conducted to evaluate lines from fourteen varietys of supersweet corn, and the selected lines were 1103(S5) family lines. 514 inbred lines has thiner pericarp tenderness. And 360 F1 combinations wereproducts.
2.Purple waxy corn: 2 new F1 hybrids were selected in new varieties test for better quality, and were conducted to evaluated the yield in the regional trial. And the TAPH89-05 hybrids were selected for higher ear yield, uniform ear type, and better pericarp tenderness in purple waxy corn, and released at 29/11/2005.
3.White waxy corn: Select for plant and ear type was conducted to evaluate lines from twelve germplasm of white waxy corn, and the selected lines were 392 S5 inbred lines. The 85 S5 inbred lines has thiner pericarp thickness in the 392 S5 inbred lines. .
4.TNW green corn: 80 testcrosses had producted from thin pericarp in TNW corn, and the 19 F1 has better quality .The TAWH92-9 had more fresh ear weight than the TN22( ck.) Variety.
