 Abstract
This study was carried out to evaluate the quality properties, fatty acid composition and amino acid composition of major Korean inbred lines and hybrids of maize for corn breeding. Protein content of seeds was 9.0%, which was slightly lower than those of inbred lines, 11.4%, and seeds, 10.9%. in hybrid maizes. Lipid content of seeds of hybrid maizes was 4.2%, slightly higher than those of inbred lines, 3.3%, and seeds, 3.6%. However, there was no significant difference in ash content. The amount of linoleic acid in inbred lines, and seeds of hybrid maizes was highest among all fatty acids and followed by oleic acid, palmitic acid, stearic acid and linolenic acid. The composition of saturated fatty acid of seeds was 17.6%, similar to seeds but it was lower than that of inbred lines. The composition of unsaturated fatty acid of seeds was 82.4%, similar to seeds but was higher than inbred lines. The content of leucine of seeds was lower than inbred lines and seeds. The content of valine, serine, threonine, cysteine, aspartic acid, lysine, arginine, histidine of seeds was higher than inbred lines and seeds. MMA (monoamino monocarboxylic acid) in inbred lines, and seeds of hybrid maizes was highest among all amino acids and followed by DMA (diamino monocarboxylic acid) and AAA (aromatic amino acid).
