Using spring soft wheat varieties to determine test environment parameters

The article presents the results of determining the parameters of 12 research environments. The research was carried out using 6 varieties of spring soft wheat of the middle early group of ripeness on the basis of "yield". Identified environments that have a stabilizing background combined with high productivity and typicality: Barnaul (2014, 2015), Kytmanovo (2014), Krasnoshchekovo (2014-2015). In the conditions of Kytmanovo in 2015, a high yield was formed, but the Sek indicator (differentiating ability of the medium) is high - this is an analyzing background, such backgrounds should be used at the initial stage of selection.
