This work aimed to establish the relationship between the variability of chemical composition and physiological quality of soybean seeds. Three lots were used for the cultivars Tabarana, Tucunaré and Monsoy 8866. The analyzes were germination, seedling emergence, tetrazolium test, oil content, protein and free fatty acids. The lot 3 of Tabarana cultivar presented higher germination compared to the others. By the tetrazolium test, the seed viability was similar between lots and cultivars. The seedling emergence was higher in Tabarana cultivar and also from seeds of lot 3. The contents of protein, oil free fatty acids in soybean seeds were variable between lots and reflected in the average difference between cultivars. The protein content was higher in Tabarana cultivar and oil content showed higher value in cultivar Monsoy 8866. The free fatty acids was lower in seeds of Tucunaré cultivar. The chemical composition varies among seed cultivars and lots, maintaining relationship the quality of soybean seeds.
