The results of winter soft wheat breeding in the southern forest-steppe of the West Siberia

The expansion of winter wheat sowing areas is one of the reserves to increase grain production in the Siberian region. The winter wheat varieties “Omskaya ozimaya”, “Omskaya 4” and “Omskaya 5”, developed in the Omsk Agricultural Research Center (ARC), have become popular here. The winter wheat varieties “Siberskaya Niva”, “Severnaya Zarya”, “Omskaya 6” and “Yubileynaya 180”, which were used to develop a new hybrid material, made a definite contribution to the development of winter wheat breeding. The new variety of the Omsk Agricultural Research Center (ARC) is characterized with high yields, winter tolerance and resistance to lodging. The grain of this variety meets the requirements applied to valuable wheat. In 2018 the variety “Priirtyshskaya” was introduced in the State List of Breeding Achievements in the East Siberian Region. The purpose of our research is to identify forms of winter soft wheat with high yields and grain quality, adapted to local conditions. The study was conducted in 2015-2017. The object of study were winter wheat samples from competitive varietal testing. In this breeding nursery, there have been identified the promising lines “KSI 34/17”, “KSI 35/17” and “KSI 38/17”. They are characterized with higher yields, exceeding the standard variety “Omskaya 4” on 0.86-1.12 t/ha. The advantages of these lines are high winter tolerance, resistance to lodging and high grain quality. Due to some indicators of grain quality, you can select the variety line “KSI 35/17”. The line has larger percentage of protein in kernels, good rheological properties of dough, bread volume and general baking estimation compared with the standard variety “Omskaya 4”. The lines “KSI 34/17”, “KSI 38/17” possess good technological and baking indicators of grain quality
