玉米品種選育

Abstract

1. 超甜玉米去苞葉鮮果穗產量介於5.82–9.40 kg/9.6m2，以A6 與A10 產量較高，顯著較對照種 (好滋味) 高產。 2. 三系種超甜玉米新品系產量比較試驗去苞葉鮮果穗產量介於807–1088g/5 ear，以(彩白3Dx彩白20) x 新600,25-1、(彩白18Bx 彩白3) x 好4-2、(彩白20x 彩白3) x 好58-1、(彩白18Bx彩白3) x 興農506-74 等產量較高，與對照種 (雪珍、白美人) 無明顯差異。 3. 2016 秋作霧峰試區，硬質玉米新品系籽粒產量的表現1M10 × Hi31 (8,356 kg/ha) 、1M15 × Hi31 (8,331 kg/ha) 與對照種MF3 (8,304 kg/ha)、MF103 (8,595 kg/ha) 間無明顯差異；但較對照種台農1 號 (6,160 kg/ha) 高產，分別增產35.6%及35.2% ；同時較對照種TN24 號分別高產13.4%與13.0%。 4. 植株鮮重品系的表現以703-87 x 888M 與963-38 x 1M10 表現最高產。 1. Super-sweet corn, the A6 (SN600, 25-1 x SW3A), and A10 (GH10 xSW3A) new hybrids had higher ear yield than the chick variety (Hu - jw) in the regional trial. 2. Super-sweet corn, the three- way new hybrids were evaluated in new varieties test for better quality, and 4 three- way new hybrids were selected. The (SW3D x SW20) x SN600 25-1, (SW18B x SW3) x Hu4-2, (SW20 x SW3) x Hu58-1, and (SW18B x SW3) x SN506-74 new hybrids had higher ear yield in the new entries trial. 3. The feed corn, select for plant and yield was conducted to evaluate, new hybrids 1M10 × Hi31 (8,356 kg/ha, 1M15 × Hi31 (8,331 kg/ha) had higher grain yield than TN24, TNG1. 4. In the forage corn were to evaluated the total fresh weight in the new entries trial, and 703-87 x 888M and 963-38 x 1M10 hybrid crosses were selected for higher fresh weight then the ck variety.
