Probability of High-Quality Grain Formation With Spring Wheat Varieties of Different Origin in the Steppes of Orenburg Ural Region

Abstract

Analysis of the technological qualities of spring wheat grain showed, that high-natural grain can be obtained from the varieties of Orenburg and Samara selection in 75.0% of the years, and the Saratov breeding - 62.5% of years. All studied varieties of spring durum wheat form high-natural grains of 87.5% years. Grain with high glassiness is characteristic to varieties of spring wheat of Samara breeding of 75.0% years and Orenburg and Saratov breeding - 87.5% years. High glassiness grain of spring durum wheat varities of Samara and Saratov breeding constitute 87.5% of the years, and the Orenburg selection of 100% of the years. Grain, which protein content is greater than 14% or more in Orenburg steppe, was formed only by varieties of soft wheat Orenburg breeding and Ukrainian durum wheat breeding in years of 12.5%. Grain, corresponding to 1 class by the content of gluten, in our experiments was obtained from following varieties: soft wheat of Orenburg and Samara selection in 75.0% of the years, and the Saratov - in 62.5% of the years; durum wheat of Orenburg and Samara selection in 25.0% of the years, and Ukrainian - 62.5% years. The investigation of soft wheat varieties form grain of I-III quality group and grade durum wheat - II-III quality group.
