The objective of this work was to evaluate the electrical conductivity test to estimate the physiological potential of canola seeds, aiming to establish an efficient methodology for its execution. The experimental design was completely randomized with hybrids and 4 replications (lot 1 – Hyola 571 CL; lot 2 – Hyola 433; lot 3 – Hyola 76; lot 4 – Hyola 401; lot 5 – Hyola 61 and lot 6 – Hyola 50). Physical quality (degree of moisture and weight of a thousand seeds) and physiological quality (germination, first germination count, germination speed index, seedling emergence, emergence speed index, root length, shoot length and total, seedling dry mass). For the electrical conductivity test, variations in water volume (25, 50, 75 ml), number of seeds (25, 50, 75 and 100 seeds) and exposure time (1, 3, 6, 9.12 and 24 hours). Four replicates of each lot were evaluated. The electrical conductivity test was efficient for evaluating the physiological potential of canola seeds, with combinations of 50 or 75 seeds immersed in 75 ml of deionized water, for periods of 6 and 9 hours, providing better stratification of lots.
