Abstract

甜玉米：蒐集國外甜玉米品種，供自交系育成之材料。95 年共育成1498 個S1-S6 自交系。並育成超甜玉米雜交品系，進行結合力檢定，其中共有17 個品系的表現優於對照品種。白玉米：育成670 個S2-S6 自交系。雜交品系比較試驗結果以PWH95(S)-26 之公頃鮮穗產量較對照種(ck1)台南22 號及(ck2)台南白增產20-94%，官能品嚐亦優於對照品種(ck2)台南白。新品系區域試驗PWH93-28 朴子及善化試區平均鮮穗產量10,400 公斤/公頃，官能品嚐評分為83 分，均優於對照種(ck2)台南白。糯玉米：95 年春自大陸引進廣東白糯、珍糯1 號、菲律賓引進IPB 及泰國Gc-01 等白糯共5 品種，播種後調查農藝性狀，並自交分離S1，秋作續作S2 篩選，露菌病檢定122 品系，結果有Phi 10 等36 品系對露菌病具有抗性。組合力檢定春作有75 品系供試結果以PWX95SA-33 品系最早熟，含苞葉產量以PWX95SA-41 品系11,400 公斤/公頃最高，比對照種美珍增產13％。新品系比較試驗有9 品系參試其中以PWX95SB-6 品系含苞葉產量13,000公斤/公頃為最高，比對照種增加27％。官能品嚐87 分，比其他品系為優。理化性檢定可溶性固形物為12.7％，oBrix 比對照種為佳。新品系區域試驗本場育成之PWX 93-5 品系表現良好，在朴子及學甲試區產量都比對照種美珍白糯為優。飼料玉米：春作有5 品系參與新品系比較試驗，以台南20 號及台農1 號對照種，試驗結果，參試品系的乾籽粒產量都高於對照種，其中以PGH95SA-1 的4,900 公斤/公頃為最高，比台南20 號增加70％，比台農1 號增加182％。秋作有8 品系參與比較試驗，以PGH95FA-8的7,475 公斤/公頃為最高，比台南20 號增加1％，比台農1 號增加14％。 1. Sweet corn : Different sweet corn varieties were introduced form other countries, and these germplasms were used to isolate inbreds. 1,498 sweet corn inbreds were developed in spring crop, 78 hybrids were test in yield trail, and 17 hybrids showed higher yield than the check. C2 population was developed by recurrent selection in population improvement. 2. White corn : 670 S1─S6 lines were obtained in spring crop 2006. In the single cross test held in 2006 spring crop, The hybrid “PWH95S-26” performed the better in ear production than the Tainan No. 22 (ck1) and Tainan white (ck2) by 20 to 94%. In sensory evaluation for eating quality, the hybrid also got the higher scores than the checks. 3. Glutinous corn : 3 varieties were introduced from mainland China and other countries, and 484 S1─S6 inbreds were obtained. In the yield test held in 2006 spring crop, PWX93SB-6 performed the best in ear production 13,000 kg/ha and outyielded than the check, Meizein by 27%. 4. Feed corn : There were five hybrids performed good seed production, and they were higher than check varieties in 2006 spring crop. However, only PGH95FA-8 had high seed yield 7,475 kg/ha and better than the checks, TN 20 and TNG 1, respectively.
