“…Nevertheless, the EUCLEG collection is strongly structured, with a distribution of genetic diversity over five subgroups. In agreement with previous reports by Žulj Mihaljević et al (2020) , our analysis confirms that soybean accessions from Southern Europe are closely related to those from United States and Canada. Soybean accessions from Eastern and Western Europe contain a range of diversity as they were distributed over all five subgroups (G1 to G5).…”

“…Based on the responsiveness of soybean flowering and maturity to photoperiod and temperature, a total of 13 distinct maturity groups have been defined, of which only early maturing types (maturity groups MG000 to MGII) are suitable for cultivation in Europe ( Kurasch et al, 2017 ). Previous studies have shown a narrow genetic base of the European soybean germplasm ( Hahn and Würschum, 2014 ; Žulj Mihaljević et al, 2020 ), which can be due to the use of only a few ancestors originating from Canada, North America, Japan and China for breeding in Europe ( Ristova et al, 2010 ; Hahn and Würschum, 2014 ; Miladinović et al, 2018 ). In addition, the original material used for breeding probably carried a low level of genetic diversity, as both pedigree and molecular marker data have indicated a narrow genetic base of North American and Canadian germplasm ( Gizlice et al, 1996 ; Vaughn and Li, 2016 ; Bruce et al, 2019 ).…”

“…Our current knowledge on the origin and genetic relationships within European soybean germplasm is still fragmented. Main reasons are the limited number of accessions (covering only a fraction of the total genetic diversity) that were included in previous studies (e.g., 28 accessions in Ristova et al (2010) , 93 in Hahn and Würschum (2014) , 75 in Kurasch et al (2017) and 97 in Žulj Mihaljević et al (2020) ), and/or the low number of genetic markers that were used for screening. Miladinović et al (2018) , genotyped 445 accessions at 85,000 SNP loci, but only used the 38 SNPs located in maturity genes for analysis, and focused on materials from one European breeding program.…”

Targeted and untargeted selections including domestication and breeding efforts can reduce genetic diversity in breeding germplasm and create selective sweeps in crop genomes. The genomic regions at which selective sweeps are detected can reveal important information about signatures of selection. We have analyzed the genetic diversity within a soybean germplasm collection relevant for breeding in Europe (the EUCLEG collection), and have identified selective sweeps through a genome-wide scan comparing that collection to Chinese soybean collections. This work involved genotyping of 480 EUCLEG soybean accessions, including 210 improved varieties, 216 breeding lines and 54 landraces using the 355K SoySNP microarray. SNP calling of 477 EUCLEG accessions together with 328 Chinese soybean accessions identified 224,993 high-quality SNP markers. Population structure analysis revealed a clear differentiation between the EUCLEG collection and the Chinese materials. Further, the EUCLEG collection was sub-structured into five subgroups that were differentiated by geographical origin. No clear association between subgroups and maturity group was detected. The genetic diversity was lower in the EUCLEG collection compared to the Chinese collections. Selective sweep analysis revealed 23 selective sweep regions distributed over 12 chromosomes. Co-localization of these selective sweep regions with previously reported QTLs and genes revealed that various signatures of selection in the EUCLEG collection may be related to domestication and improvement traits including seed protein and oil content, phenology, nitrogen fixation, yield components, diseases resistance and quality. No signatures of selection related to stem determinacy were detected. In addition, absence of signatures of selection for a substantial number of QTLs related to yield, protein content, oil content and phenological traits suggests the presence of substantial genetic diversity in the EUCLEG collection. Taken together, the results obtained demonstrate that the available genetic diversity in the EUCLEG collection can be further exploited for research and breeding purposes. However, incorporation of exotic material can be considered to broaden its genetic base.

High-vigor soybean seeds can result in the rapid and uniform emergence of seeds under a wide range of field conditions. We aimed to explore the quantitative trait loci of seed vigor traits and superior allelic and carrier materials from the soybean in northeast China. A total of 257 improved lines and 104 soybean landraces were used to evaluate seed vigor, using normal seedling fresh weight, normal seedling length, main root length, hypocotyl length, and germination percentage, in 2018 and 2019. In this study, the different degrees of LD was detected not only among syntenic markers but also among nonsyntenic ones, suggesting that there had been historical recombination among linkage groups. A total of 19 and 10 simple sequence repeat (SSR) markers associated with seed vigor were detected in improved lines and soybean landraces in 2018 and 2019, respectively. Our results also showed five SSR markers co-associated with two or three vigor traits. In addition, 41 superior alleles and their carrier materials were mined. Based on the elite alleles detected, the best cross combinations for improving seed vigor traits were proposed. The results demonstrate that association mapping is a valuable foundation for molecular breeding for soybean seed vigor.

Objective Soybean is an important plant used for food, feed and many industrial purposes. Interest in soybean breeding is growing in Central Europe, including Poland. A very large number of soybean accessions are stored in gene banks, but less than 1% of them have been used for breeding. Here, we present genotypic data as well as phenotypic data on plant and seed performance, including seed chlorophyll fluorescence traits, and on yield components within a collection of soybean accessions that are conserved in the Polish Gene Bank at the Plant Breeding and Acclimatization Institute-National Research Institute. Results The materials used consisted of sub-collections: 79 Polish genotypes, including old traditional cultivars, 24 Canadian, 21 American, 21 Swedish and 31 from Central and Eastern European Countries, 9 from France and 6 from Japan. In total, 9602 high quality SNPs were derived from DArTseq, a method utilising GBS technology. GWAS, performed with the BLINK model, revealed that a total of 41 significant SNPs were mapped for days to flowering, flower colour, plant height, days to pod formation, 100 seed weight, pod colour, seeds and hilum colour and steady-state chlorophyll fluorescence under light (Ft_Lss). This is the first report about the diversity of traditional old Polish soybean cultivars.
