Abstract. At the Federal State Budgetary Institution All-Russian Research Institute of Corn, breeding work is being carried out to create promising white-grain corn hybrids with an improved chemical composition of the grain. The article presents the results of studies of white grain corn hybrids bred by the All-Russian Research Institute of Corn on the chemical composition of the grain: protein, oil, starch. Samples of white grain corn hybrids of different ripeness groups were studied – 11 mid-early and 6 mid-ripening, including standards. As a result of the research, it was noted that the grain of white corn hybrids is characterized by a high starch content. 75 % of mid-early white-grain hybrids contain 68.5–72.1 % of starch. In terms of protein content in grain, only 8 % of the total number of hybrids studied are worthy of attention. Almost all experimental hybrids had an average oil content of 4.2–5.1 %. Hybrids of the mid-ripening ripeness group were distinguished by a high starch content of 68.7–72.9 % and a low protein level. The number of hybrids with an average oil content of 4.2–5.1 % amounted to 83 % of the total number of hybrids. Data analysis made it possible to identify the best experimental hybrids that combine high yields with high starch content. The mid-early hybrid 280–11 contains 72.1 % starch and the mid-season 278–153 – 72.9 % with a yield of 7–8 t/ha. Promising white grain corn hybrids with increased content of basic nutritional nutrients have been identified.
