Leaf characteristics of main stem and tiller of IK type maize (IK//IRI/B68) were compared with those of Jinjoo Ok hybrid which are not usually tillered. A total of nine leaves from flag leaf to the third or the fourth leaf below ear-bearing node were sampled from each stem or tiller. There was no significant difference in mean leaf length between IK//IRI/B68 and Jinjoo Ok. But the mean leaf width of IK//IRI/B68 was about 2 cm narrower than that of Jinjoo Ok. The mean leaf area of the IK//IRI/B68 was also smaller than that of Jinjoo Ok due to the narrower leaf width. There were not significant differences in mean leaf characteristics between main stem and tillers of IK//IRI/B68. The longest leaf was the leaf below the ear-bearing node and the widest leaf was the leaf just above the ear-bearing node. Mean length, width and area of leaf on main stem and tillers were similar. Coefficients of variation calculated for individual leaf indicated that the leaves near the ear-bearing node were more uniform than others. The leaf area measured was significantly greater than that estimated by formula, length x width x 0.75. New constant to estimate leaf area of tillering maize was derived as 0.8
