ABSTRACT
The article presents the results of three-year study of the world’s gene pool of corn hybrids on leached black soils in the forest-steppe zone in Western Siberia. Peculiarities of using the biological potential of grain productivity have been studied. It has been shown that increased intensification of production allows using the high biological productivity potential of corn grain of various ecological and geographic profiles. In the conditions of irrigated agriculture in the forest-steppe zone of Western Siberia, the maximum observed yield of corn hybrids was approximately 8 t/ha. It has been found that corn hybrids Talisman (the yield rate of 8.4 t/ha), Gitago (the yield rate of 8.3 t/ha), Delitop (the yield rate of 7 t/ha) and Falcon (the yield rate of 6.8 t/ha) featured high ecological plasticity in the extreme conditions of Western Siberia, and ensured high productivity with good quality of grain products. The highest productivity of Kubansky 101 corn grain (the maximum yield rate of 6 t/ha) was reached at the seeding rate of 6-7 grains per meter
