“…For this, we need crops with adaptive capacities to changing environments. Domesticated crops have been under human selection pressure for ages and their gene pool is limited by the domestication bottleneck (Tanksley and McCouch 1997). To broaden their genetic diversity, valuable genetic resources can be found within crop wild relatives (CWR).…”

“…To address this challenge, the FIGS ("Focused Identification of Germplasm Strategy") tool was introduced, building upon earlier work by Michael Mackay (Mackay 1985, Caradus et al 2012. FIGS employs two main approaches: "FIGS filtering," which filters accessions, based on expert knowledge and environmental data (Bouhssini et al 2009) and "FIGS modelling," which predicts the presence of genetic resource of interest in uncharacterised accessions using field trial data (Sunitha et al 2023). All these methods primarily serve to filter collections stored in gene banks.…”

“…Germplasm resources with superior traits such as high yield, disease and insect resistance, and abiotic stress tolerance are the vital foundation for breeding programs. [13]. Cao et al [14] evaluated the salt tolerance of 51 soybean germplasms from Indonesia using a hydroponic method and analyzed six varieties with enhanced salt tolerance.…”

Salinization is a global agricultural problem with many negative effects on crops, including delaying germination, inhibiting growth, and reducing crop yield and quality. This study compared the salt tolerance of 20 soybean varieties at the germination stage to identify soybean germplasm with a high salt tolerance. Germination tests were conducted in Petri dishes containing 0, 50, 100, 150, and 200 mmol L−1 NaCl. Each Petri dish contained 20 soybean seeds, and each treatment was repeated five times. The indicators of germination potential, germination rate, hypocotyl length, and radicle length were measured. The salt tolerance of 20 soybean varieties was graded, and the theoretical identification concentration was determined by cluster analysis, the membership function method, one-way analysis of variance, and quadratic equation analysis. The relative germination rate, relative germination potential, relative root length, and relative bud length of the 20 soybean germplasms decreased when the salt concentration was >50 mmol L−1, compared with that of the Ctrl. The half-lethal salt concentration of soybean was 164.50 mmol L−1, and the coefficient of variation was 18.90%. Twenty soybean varieties were divided into three salt tolerance levels following cluster analysis: Dongnong 254, Heike 123, Heike 58, Heihe 49, and Heike 68 were salt-tolerant varieties, and Xihai 2, Suinong 94, Kenfeng 16, and Heinong 84 were salt-sensitive varieties, respectively. This study identified suitable soybean varieties for planting in areas severely affected by salt and provided materials for screening and extracting parents or genes to breed salt-tolerant varieties in areas where direct planting is impossible. It assists crop breeding at the molecular level to cope with increasingly serious salt stress.
