The reaction of modern hybrids of grain sorghum to the temperature of the medium and seed germination in laboratory and field conditions was studied. In the course of many years of field research conducted in the conditions of the Eastern Forest-Steppe, the effect of hydrothermal conditions during the sowing period of seedlings on field germination of seeds, density of seedlings and weight of dry sorghum plants during the period of tillering has been established. A close correlation was found between the SCC and the factors under study.
