The controlled deterioration test (CD) is an ageing technique similar to the accelerated ageing test (AA) that permit better seed moisture and temperature control during the ageing period. The seed moisture content in the CD test is adjusted previously, providing a uniform stress in all seeds under evaluation this does not occur in the AA test, where each seed moisture content is raised without control during the test period, until it reaches the equilibrium moisture content with the chamber environment. Thus, seeds may reach the equilibrium at different times and they are submitted to distinct level of stress, as well as damaged by the presence of storage fungi (e. g., Aspergillus and Penicilium), that may occur during the test conditions used for screening genotypes for seed quality (41ºC during 72 or 96 hours). Therefore, seed treatment is required and may interfere negatively in the selection process. The research was conducted with 29 seed lots of 13 cultivars of five vigor levels according to the tetrazolium test rank as follows: <49%, 50-59%, 60-74%, 75-84% and >85%. The experimental design was a completely randomized design and the means were compared by the Tukey test at 5% of probability. The following conclusions could drawn: i) the CD test is reliable to identify distinct vigor levels of soybean seeds, which may result from different levels of seed quality among seed lots and cultivars; ii) the accurate information provided by the CD test fulfill the requirement for use in screening soybean genotypes for high seed quality.
