The aim of this study was to analyse different batches of saved soya seeds produced in the northern region of the state of Rio Grande do Sul, Brazil. The aim was to identify the physical, physiological and sanitary qualities of these seeds. Currently, the seeds saved by producers do not have a standard to be followed and used, as the areas are chosen based on the judgement that they are the best, making it possible to store them in bags or sacks in the post-harvest period, without the necessary mapping. What should be taken into account is that these seeds should, as a rule, be stored with the right moisture content, free from mechanical damage and weed seeds, and with all the necessary field treatment that a supervised seed field or sowing centre has. Saved soya bean seeds do not have the minimum stability needed to be safe for sowing, nor do they have the physical, physiological and sanitary quality to be considered a future problem for producers.
