The assessment of the collection samples of soybean of various ecological and geographical origins in the conditions of the Amur region

The research objective was studying genetic sources having high efficiency and increased protein content in soy beans for their inclusion in selection process. Experimental part of the study was performed in 2018-2019 on the site of field crop rotation of the Laboratory of Selection and Genetics of FSBSI ARSRI of Soybean, V. Sadovoe Tambov district, Amur Region. The results of studying of 205 numbers of the soy of foreign and domestic selection of various ecological and geographical origins, including 71 varietal samples of the collection of white-flowered and violet-flowered forms of soy of selection were presented by FSBSI ARSRI of Soybean. Weather conditions in the years of carrying out the research differed in temperature conditions and moisture supply; it allowed carrying out an objective assessment of the collection material. The largest number of the samples of gene pool was presented by Chinese (49.3 %) and Russian varieties (37.1 %). As a result of comparative assessment of highly productive varietal samples from Canada, USA, China, Serbia, Japan and Russia, 28 varieties and varietal samples were selected as the sources for crossing. The greatest productivity was noted in samples No. 1 2014J72 (China), NC Katya (Serbia) and individual selection of the soy variety Marinata made in ARSRI of Soybean - 3.8 t/hectare (+1.0 t/hectare to st). 36 sources of increased protein content in soybeans with various vegetation periods were allocated. The samples of the world collection of the soy from Krasnoyarsk State Agrarian University combining short period of vegetation (76-90 days) with high protein content in beans (42-45 %) are of special interest. The sources combining high efficiency with increased protein content in beans, adapted for the conditions of Amur Region have been found. These varietal samples are recommended for crossing to create new high-protein genotypes of different groups of ripeness.
