The variety of spring soft wheat Moscovskaya 35, zoned in 1971, is an outstanding breeding achievement. It is included in the State Register of approved varieties and recommended for the fourth region in Russia (Volga-Vyatka). In this paper, an assessment was made of the variation in the structure elements of the harvest of spring wheat variety Moskovskaya 35 depending on the growing season of the year 2014-2018 in the conditions of the southern part of the Volga-Vyatka region in Russia. A study of the morphostructural indicators of spring wheat of the variety Moskovskaya 35 for five years revealed that the most stable of those is the mass of 1000 grains (coefficient of variation – 13.1%), and the most variable is the length of the ear (coefficient of variation – 20.6%). It was found that the vegetation weather conditions for the years of testing had a strong influence on the intravarietal variability, which is confirmed by the calculation of correlations between yield and the sum of active temperatures during the vegetation period (regression coefficient – 0.92). Analysis of the coefficient of variation showed that the variety Moscovskaya 35 has good ecological plasticity, the coefficient of yield variation was 21.4%.
