Mid-season spring soft wheat variety Bejskaya for southern areas of the Krasnoyarsk region

The objective of research is to create and study a mid-season soft wheat variety with a high level of adaptability to regional conditions based on a set of economically valuable traits. Field studies to create and evaluate the variety were conducted in 2009-2023 on the experimental fields of the Krasnoyarsk Research Institute of Agriculture. The experiments were carried out on a fallow predecessor with a seeding rate of 5 million viable grains per hectare. The plot area in the competitive variety testing was 30 m2 in four repetitions. The Bejskaya variety was obtained by individual selection from the Ekada 70 × K-295-2 hybrid combination. On average, over 7 years of competitive variety testing, the variety yield was 3.77 t/ha (from 2.62 to 5.40 t/ha). The advantage over the Altajskaya 75 standard was 0.33 t/ha. The yield variation by years was 27.1 %, compared to 31.8 % for the standard. Since 2021, the Bejskaya variety has been tested at variety testing sites in Siberia. Positive results were obtained at all variety testing sites in the Krasnoyarsk Region, except for Uzhursky. Increases to the standard ranged from 0.18 (Uyarsky variety testing site) to 1.42 t/ha (Karatuzsky variety testing site). In a number of variety testing site in other areas of Siberia, increases to the standards amounted to 0.30 to 0.85 t/ha. The variety has high drought and heat resistance, and is resistant to loose smut. In terms of grain quality, it is included in the list of valuable wheats. It is listed in the State Register since 2023 and recommended for cultivation in the southern areas of Krasnoyarsk Region and Omsk Region. Patent № 12547 dated 06/05/2023 was received for the Bejskaya variety.
