Abstract Sorghum is an adaptive culture, its high plasticity, dry and heat resistance is due to African origin. Grain sorghum has the ability to grow where the worst conditions for other crops have formed: on low–fertile sandy soils, in conditions of moisture deficiency, the crop easily tolerates high temperatures during flowering and forms a wax coating, protecting itself from overheating, pests and diseases. The aim of the study was to determine the chemical component of the seeds of the studied hybrids of grain sorghum. To establish the content of proteins, fats, carbohydrates, as well as vitamins, macro– and microelements in hybrids of various breeding. In terms of nutritional value, namely, a high content of proteins, fats and carbohydrates among the studied hybrids, the American hybrid Prime stood out, with a calorie content of 320 kcal., And from the French hybrid Burggo with a calorie content of 318 kcal. The highest thiamine values were found in the seeds of American selection hybrids – Yuki and Prime, which amounted to 0,43–0,45 mg/100 g, respectively. The seeds of the American hybrid of sorghum–grain – Prime set the highest biotin content – 0,018 mg/100 g. The studied hybrid of sorghum–grain American Prime breeding was characterized by a high content of Na, at a level of 26 mg/100g. As a result of the studies, it was found that the content of cobalt (Co) in all the studied hybrids of sorghum grain was in the same amount and amounted to 2,0 mg/100 g A high Al content was found in the seeds of French hybrids, these indicators were at a level of from 1,550 to 1,555 mg/100 g. According to the boron content (B), the American Yuki hybrid turned out to be the best, since the content of this microelement was 0,347 mg, the content of the French Burggo hybrid less boron – 0,325 mg. The seeds of the American hybrid of sorghum grain Prime have the highest content of such a trace element as zinc at the level of 2,15 mg/100 g.
