The results of field experiments on the study of the duration of the growing season and its main phases in 33 samples of Siberian selection under the conditions of the Krasnoyarsk forest-steppe showed that the variability of the interphase periods of shoots - earing and earing - waxy ripeness is largely determined by the growing conditions (31.1 and 37.4% respectively) in relation to the growing season (0.9%). The duration of the growing season is primarily determined by the genotypic characteristics of wheat samples (88.3%). The contribution to the phenotypic variability of the studied traits depends on the ripeness group. We identified wheat samples of interest for hybridization, with a longer interphase period - sprouting - earing and shortened - earing - waxy ripeness.
