| Summary: | The biological features and economically useful traits of the spring soft wheat variety Kuraginskaya 2 were studied. The studies were carried out in 2010-2021 on experimental fields and in laboratories of the Krasnoyarsk Research Institute of Agriculture. Sowing was carried out on a fallow predecessor with a rate of 500 germinating grains per 1 m2. The soil of the experimental site is leached chernozem. Variety Kuraginskaya 2 was created by the method of intraspecific hybridization and subsequent selection from the population K-817xKazakhstanskaya 10 of Lutescens variety. The variety is mid-season, the duration of the growing season is at the level of standards. In competitive variety testing the average grain yield was 27.7 centner/ha. The advantage over the Omskaya 33 standard is 3.8 centner/ha. Kuraginskaya 2 surpasses Omskaya 33 in terms of 1000-grain weight and ear grain content. The maximum yield of 71.0 centner/ha was obtained in 2019 at the Uyar variety plot. The variety has high ecological plasticity, resistant to lodging and root rot. Grain quality corresponds to a good filler.
