YIELD STRUCTURE AND GRAIN QUALITY OF SPRING WHEAT VARIETIES OF ALTAI AND FOREIGN SELECTION (TYUMENTSEVSKY DISTRICT, ALTAI KRAI)

Abstract

Wheat is one of the three major agricultural crops worldwide. The yield of any agricultural crop, including spring soft wheat, largely depends on compliance with regional requirements during its cultivation, while variety is one of the decisive factors. The current research aims to identify the difference in the yield structure and grain quality of spring wheat varieties of Altai and foreign selection for the Tyumentsevsky district (Altai Krai) for the first time.
 The tasks are as follows: (1) to analyze the growing season weather conditions, (2) to compare the yield, yield structure elements, and indicators of grain quality, and (3) to find the best variety of spring soft wheat. Sampling during the experiment and processing of the results was carried out in accordance with standard methods. There was a difference in the yield structure and grain quality of spring wheat varieties of Altai and foreign selection in the Tyumentsevsky district of Altai Krai. The 2020 growing season was extreme, with droughts, higher temperatures, and precipitation lower than in multiannual terms.
 A comparison of varieties has shown the highest yield variability. The highest amount of grains (21.1 c/ha) was received by Variant 2 – Altayskaya 75 (elite seeds). The research results have shown that it is best to use the varieties of local selection to obtain the maximum yield of spring soft wheat in the conditions of the Tyumentsevsky district of Altai Krai.
