| The growth and yield performance of 19 new com hybrids were evaluated. Results showed that all hybrids had a superior growth performance in the drained-paddy than in the upland field except for daeyul ${ imes}$ cheongdo and hyoryeong ${ imes}$ cheongdo in plant height, cheongdoyeop ${ imes}$ wx-3 in tassel1ength, and cheongdo (black) ${ imes}$ wx-3 in number of tassel branch. The same hybrids, except cheongdoyeop ${ imes}$ wx-3, obtained lower ear quality in drained-paddy field compared to upland in terms of ear weight, and ear and grain setting length. The highest yield in the drained-paddy and upland fields was obtained in the hybrids ks5wx ${ imes}$ ks6wx ${ imes}$ cheongdo (1,633.3kg ${cdot}$ $10a^{-1}$) and daeyul ${ imes}$ wx-3 (1,516.7kg ${cdot}$ $10a^{-1}$), respectively. Highest yield among the wx-3 crosses was obtained in daeyul which was 1,583.3kg ${cdot}$ $10a^{-1}$ and 1,516.7kg ${cdot}$ $10a^{-1}$ in drained-paddy and upland field, respectively. For the crosses of wx-8, highest yields were recorded in the cultivar bugye50 (1,466.7kg ${cdot}$ $10a^{-1}$) and seokgu12 (1,384.6kg ${cdot}$ $10a^{-1}$) for drained-paddy and upland field, respectively. In the case of cheongdo, highest yields were obtained in ks5wx ${ imes}$ ks6wx (1,633.3kg ${cdot}$ $10a^{-1}$) and seokgu14 (1,111.1kg ${cdot}$ $10a^{-1}$) for drained-paddy and upland field, respectively. Result also showed that the drained-paddy soil had better physicochemical properties than the upland. The relatively high performance in terms of growth parameters and yield of com hybrids planted in the drained-paddy field is in agreement with the higher organic matter and micro-element content of drained-paddy field. |
