Ecological varieties research of spring wheat in northern forest steppe in Chelyabinsk region

The studies were carried out in 2017-2022 in the field experiment on the fields of the primary seed production department of the crop production complex of LLC «Chebarkulskaya Ptitsa». The aim of the research was a comparative ecological study of varieties of spring soft wheat of different maturity groups in order to select an assortment that provides the maximum stable yield in the bioclimatic conditions of the northern forest-steppe of the Chelyabinsk region. The studied varieties of spring soft wheat belong to three groups of maturity - medium-early, medium-ripening and medium-late. In each of these groups, we have identified the most productive varieties in comparison with the standard variety. By origin, the standards are in all groups of the Chelyabinsk selection, the Ekaterina variety was obtained by scientists from Yekaterinburg, Ulyanovskaya 105 is a variety of the Ulyanovsk selection, and Uralosibirskaya - of the Omsk selection. The varieties Ekaterina, Ulyanovskaya 105 and Chelyaba 75 turned out to be the most stress-resistant. The varieties Ulyanovskaya 105, Erythrospermum 59 and Yekaterina have a genotype that best corresponds to changing environmental factors. When calculating the sum of ranks in each group of the studied varieties, the most productive and adaptive varieties to growing conditions were identified: Ekaterina, Ulyanovskaya 105 and Uralosibirskaya. According to the results of the research, the varieties Ekaterina, Ulyanovskaya 105 and Uralosibirskaya were selected for cultivation in the fields of the crop production complex of the agricultural holding. Elite seeds of varieties are sold to agricultural producers of the Chelyabinsk region.
