In our country, corn occupies a leading place in the area of cultivation, both for silage and grain. The work of breeding and seed-growing centers is aimed at creating early season corn hybrids for grain use with a quick release of moisture from the grain during maturation, as well as drought resistance and cold resistance, adapted to the conditions of the Central Black Earth region. The advantage of these hybrids will be resistance to the main diseases of corn - Fusarium blight, head smut, corn smut, stem rot, southern Helminthosporium blight, bacteriosis, etc., as well as pests, among which is the most dangerous corn stem moth. This article examines six corn hybrids with different riping period from different breeding centers. The aim of the study was to determine the suitability of the corn hybrids in the conditions of the Central Black Earth Region, more precisely, in the conditions of the Orel District. For this, the grain of corn hybrids was sown in the experimental field of the village. Dobry Orel region. Long ears of corn were found in early-season hybrids SI Talisman (20.2 cm) and EC Regen (20.5 cm) and mid season hybrids EC Astrakon (20.5 cm) and EC Epilogue (20.8 cm). Among all the presented corn hybrids, the shortest ear was found in the mid-season hybrid P8521 - 16.1 cm. The largest weight of 1000 grains was observed in the mid-season EU Hubble hybrid - 340 g, the smallest one - in the early-season hybrid SI Talisman - 249 g. The highest yield was in the mid-season EU Sirrius corn hybrids - 88 c / ha and P8521 - 93.5 c / ha. You can also note the average value of this indicator in early-season hybrids SI Talisman - 81.5 c / ha and EU Regen - 79.5 c / ha, mid-season hybrid SI Rotango - 73.4 c / ha. The lowest yield was obtained for the mid-season hybrid EC Epilogue (46.7 c / ha).
