STUDENCHESKAYA NIVA - NEW WINTER SOFT WHEAT VARIETY

Abstract

Winter soft wheat is the leading crop in agriculture of Ulyanovsk region. The problem of yield increase and winter wheat production in the region should be solved, among other things, by further selection improvement of this crop. The purpose of the research was to give a comprehensive economic and biological characteristics of StudencheskayaNivanew variety of winter soft wheat of Ulyanovsk State Agrarian University, which was studied on the experimental field of the Agrarian University in competitive variety testing (2018-2022), as well as on variety plots of the Middle Volga region of the Russian Federation ( 2020-2021). It was found that the new variety is characterized by high winter hardiness (4.4 points). StudencheskayaNiva variety formed large grain (weight of 1000 grains 38.3-55.0 g) in all years of research, including years with drought events of different intensity, which indicates its high drought resistance. According to the ripeness group, the new variety belongs to mid-early-early ripening wheat. The maximum yield for Studencheskaya Niva variety was achieved in 2021 - 7.73 t/ha. The yield potential of the new variety was realized to the greatest extent under conditions of sufficient moisture, however, relative tallness (113-116 cm) and lodging were noted. Plasticity evaluation on the trait of "grain yield" showed that the variety belongs to semi-intensive type of wheat. The advantage of the new variety is stability in formation of high quality grain.
