Abstract
Early in the Lipetsk region and very early in the Krasnodar region, the soybean variety Svoya with a reduced response to day length was selected from the hybrid combination F4 D-12/14 × L-247 on early maturity, high productivity and reduced photoperiodic sensitivity traits. The soybean variety Svoya ma-tures in 93 days at the latitude of Krasnodar (45°) and exceeds the standard variety Barguzin in yield by an average of 0.32 t/ha. In competitive varieties testing in Krasnodar in 2020–2023, its yield was 1.90–3.09 t/ha. In the competitive varieties testing in Lipetsk at a latitude of 52°, the vegetation period of this variety averaged 105 days with a yield of 2.28–2.86 t/ha, which exceeded the standard variety Barguzin by an average of 0.35 t/ha. The average height of Svoya plants at the latitude of Krasnodar was 72 cm, in Lipetsk at a latitude of 52° – 86 cm. The new early soybean variety Svoya is characterized by reduced sensitivity to the range of day lengths formed at latitudes of 45–52° and high yield in the conditions of the North Caucasus and Central Chernozem regions of the Russian Federation. Such traits of the variety allow it to be recommended for cultivation in the Central, Volga-Vyatka, Central Chernozem, North Caucasus, Middle Volga, Lower Volga, Ural, West Siberian regions of the Russian Federation.
