The growth and yield performance of 19 new corn 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×cheongdo and hyoryeong×cheongdo in plant height, cheongdoyeop×wx-3 in tassel length, and cheongdo (black)×wx-3 in number of tassel branch. The same hybrids, except cheongdoyeop×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×ks6wx×cheongdo (1,633.3kg∙10a-1) and daeyul×wx-3 (1,516.7kg∙10a-1), respectively. Highest yield among the wx-3 crosses was obtained in daeyul which was 1,583.3kg∙ 10a-1 and 1,516.7kg∙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∙10a-1) and seokgul2 (1,384.6kg∙10a-1) for drained-paddy and upland field, respectively. In the case of cheongdo, highest yields were obtained in ks5wx×ks6wx (1,633.3kg∙10a-1) and seokgul4 (1,111.1kg∙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 corn hybrids planted in the drained-paddy field is in agreement with the higher organic matter and microelement content of drained-paddy field.
Abstract
The growth and yield performance of 19 new corn 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×cheongdo and hyoryeong×cheongdo in plant height, cheongdoyeop×wx-3 in tassel length, and cheongdo (black)×wx-3 in number of tassel branch. The same hybrids, except cheongdoyeop×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×ks6wx×cheongdo (1,633.3kg∙10a-1) and daeyul×wx-3 (1,516.7kg∙10a-1), respectively. Highest yield among the wx-3 crosses was obtained in daeyul which was 1,583.3kg∙ 10a-1 and 1,516.7kg∙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∙10a-1) and seokgul2 (1,384.6kg∙10a-1) for drained-paddy and upland field, respectively. In the case of cheongdo, highest yields were obtained in ks5wx×ks6wx (1,633.3kg∙10a-1) and seokgul4 (1,111.1kg∙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 corn hybrids planted in the drained-paddy field is in agreement with the higher organic matter and microelement content of drained-paddy field.
