The article presents study's results of the original material of white corn lines of ARRSI of corn breeding on the chemical composition of grain: ash, protein, fat, sugar, starch, fiber. The original material for the chemical composition assessment of corn grain is represented by 43 white corn lines. The entire material is divided into five groups (mid-early, mid-ripening, mid-late, late-ripening and very late-ripening) of ripeness. Protein, fat, ash, sugar, starch, fiber content was determined by near infrared spectroscopy using the Infra Lum FT-12 analyzer. To assess the chemical composition of corn grain, were used the data presented in the first scale of the Wide unified CMEA classifier and the international CMEA classifier of the Zea mays L species of 1997. There were studied samples of white corn lines, differing in the endosperm consistency of corn kernels – flint, dent and semi-dent. As a result of the studies, it was noted that the grain of flint white corn lines is characterized by high protein content (13.65-15.6%), medium starch content (64.42-66.72%), high fat content (5.90-6.68%). In dent lines, the protein content is very high within the range (15.71-15.85%), the medium starch content (64.11-67.15%), high fat content (6.22%). Semi-dent subspecies of white corn lines have a high protein, starch and fat content – 12.92-14.5%, 70.5%, 5.9-6.9%, respectively. The lines from various ripeness groups with an increased protein, starch and fat content
have been identified, which makes it possible to organize the breeding for the hybrids creation with increased chemical grain indices.
