Currently, creating new high-yielding varieties for a certain cultivation region is of immediate interest. The purpose of the research is to create a new early-ripening soybean variety with increased productivity, resistance to pathogens and high adaptive ability to severe natural and climatic conditions of the Far East region. The research was performed in 2009–2018 in the field crop rotation of the All-Russian Research Institute of Soybean. In the process of work, a new early-ripening soybean variety "Zolotnitsa" with growing season of 106–107 days and crop yield of 3,34 t/ha, was created, named in memory of the outstanding plant breeder V. A. Zolotnitsky, the founder of breeding in the Amur River region. A new soybean variety Zolotnitsa (breeding number Amurskaya 2425) was created for 10 years with the use of traditional breeding methods. Initial material was obtained by intraspecific hybridization of Amur and Canadian soybean samples, followed by multiple individual selection. Crossing was carried out in 2009. In 2010–2013, hybrid material was studied in the nurseries of F1–F4 generations. A constant line with stable hereditary features was isolated in 2014 in the nursery of F5 hybrids. In 2015, the constant form was studied in the check nursery. The sample analysis in competitive variety trial was carried out in 2016–2018. Testing on state variety test plots was performed in 2019–2020 in various soil and climatic zones of the Far East region. In 2021, this variety was included in the State Register of Breeding Achievements of the Russian Federation for use in production (patent No. 11592 dated 15.04.2021).
