Environmental testing of corn hybrids in various soil and climatic conditions

The article presents an analysis of two-year test data for new hybrids of maize breeding of the Samara NIISH at seven environmental points of the Russian Federation. Ecological plasticity and stability of hybrids according to grain yield are determined. The productivity of hybrids in different soil and climatic conditions was determined. Highlighted hybrids for specific conditions. The Ca 186 hybrid is characterized as the most productive and environmentally plastic among the studied samples, and the Sa 128 hybrid is characterized as an early maturing environmentally stable, having a low harvest grain moisture and a rather high productivity coefficient.
