Six corn inbreds and 15 F1 among them were used to study the combining ability for agronomic characteristics. General combining ability (GCA) was more important than specific combining ability (SCA) in ear node, lodging, row number (ear) and 100 kernel weight. Ga 209 showed the highest GCA effects in plant height, ear height and lodging, and Va 35 showed the highest GCA effects in ear length, kernel number per row, kernel number per ear and grain yield, while B84 showed the lowest GCA effects in ear length, ear diameter, 100 kernel weight and yield. The F1 between B68 x Ks15 showed the highest SCA effects in ear length, kernel number per ear and grain yield, and the F1 between B68 x Ks8 showed the lowest SCA effects in all the other characters except days to tassel and silk. Grain yield was very sinificantly correlated with plant height, ear height, ear length, ear diameter, kernel number per row, kernel number per ear and 100 kernel weight
