Cumulative indicator of quality of grain for strong wheat for conditions of strongly continental climate

Abstract

Durum wheat is second in importance after soft wheat for many countries of the world, its area is about 10% of common wheat sowing, and world grain production reaches 15-20 million tons. Identification of the role of climatic predictors in the formation of spring durum wheat on Based on the construction of computer models using the methods of mathematical modeling, it is of particular importance for agriculture.Earlier studies to identify the relationship between indicators of grain quality of durum wheat and weather predictors allowed us to establish that the formation of indicators of grain quality occurs under different weather conditions.In the work on the basis of a large experimental material on the quality of grain of two varieties of spring durum wheat, agrometeorological data of the Orenburg Regional Center on Hydrometeorology and environmental monitoring for May-August 1967-2017. Multiple regression models of the influence of weather predictors on the main indicators of the quality of hard wheat grain were built. Based on the solution of the system of regression equations, an integral indicator of the quality of spring hard wheat grain was developed for conditions of a sharply continental climate.
