Abstract
玉米GX1M與Hi31種原間存在籽粒產量之最高雜種優勢，乃將GX1M種原進行自交5代培育自交系，然後將自交授粉分離培育的自交系再與Hi31進行雜交生產、組合力評估及新品系產量比較試驗。新品系1M10 × Hi31與1M15 × Hi31與對照種「台農1號」等共進行5次新品系產量比較試驗，其中有4次新品系1M10 × Hi31其籽粒產量明顯較對照種「台農1號」高產，而1次與對照種「台農1號」無明顯差異。
In the new maize germplasm heterotic group assessment trial, it has been known that Hi31 and GX1M varieties had the best kernel yield in the heterotic group from the field experiment. As a result, five generations of self-crossing from the GX1M variety were conducted to breeding inbred lines, which were then crossed with Hi31 to produce hybrids for the combination assessment and yield trials.
