Abstract The article presents the results of research of the genetic collections of cultivated (KF, KB) and wild (KD) soybean of the gene pool of the All-Russian SRI of Soybean. The experimental part of the work was carried out in the laboratory of soybean breeding and genetics of Federal State Budget Scientific Institution “All-Russian Scientific Research Institute of Soybean” (FSBSI ARSRI) of Soybean in the period from 2016 to 2019. Field experiments were laid on the plots of selective crop rotation (Sadovoe village, Tambov district, Amur region) on meadow chernozem soil. The goal of research was to evaluate the source material of wild forms and cultural samples of soybean according to economically valuable traits and photosynthetic activity for selection of high-yielding varieties adapted to local growing conditions. As a result of research, genetic sources of various economically valuable traits were identified from the collection of wild soybean. According to a number of characteristics, soybean varieties were selected from the collections of cultivated soybean KB and KF: Kitrossa, Intriga, Nevesta, Hedi, Tundra with a growing season of 111…116 days and a yield of 3.11…3.37 t/ha, exceeding the standard Dauriya by 0.26…0.52 t/ha. The indicators of photosynthetic process intensity in plant leaves was determined in samples isolated by a complex of economically valuable traits from the collection of wild soybean: KBel-50, KA-1396, KM-695, KM-705, KT-156 (St) and from the best varieties of KB and KF collections. The analysis of the conducted studies made it possible to identify the most promising varieties and forms of wild soybean with the optimal level of activity of photosynthetic processes, which, along with sources of economically valuable traits from the collections of KD, KF, and KB, were included in crossbreeding in 2018-2019.
