In the conditions of the Donbass region, 38 varieties of grain sorghum of various ecological and geographical origin-breeding companies of Western Europe (“RAGT SEMENCES”, “EURALIS SEMENCES”, “PIONEER”), Ukraine, Russia, the international company “ADVANTA”, the American company “RICHARDSON SEED” were studied. Field research was carried out in the period from 2016 to 2018 in the experimental field of the Lugansk National Agrarian University on ordinary shallow weakly washed blackearth (chernozem) on loess-loam. It was found that the most adapted and productive (6,0 t/ha of grain or more) were early – maturing hybrids – Swift and Queyras; middle early – Solarius, PR88Y20, Bianca, Puma Star; mid-season - Bounty. The most productive (5,0 t/ha and more grain) varieties – Odessky 205, Krupinka 10, Darunok, Zersta 97. The average positive correlation between the duration of the growing season of varieties and crop yield was established. The density of the productive stem in the range from 11 to 25 panicles per 1 m2, the length of the panicle leg and the weight of 1000 grains did not have a significant correlation with the level of sorghum yield. Sorghum yield had an average and increased correlation with panicle weight, grain weight per panicle, number of grains per panicle, grain type, and medium negative relationship with plant height.
