The use of high quality seeds constitutes in one of the responsible factors of the success of a fieldwork. Because of that, this work was elaborated to evaluate the physiological quality of cotton seeds of two to cultivars Green BRS and CNPA 7H submitted to two levels of moisture content and stored for 12 months. It was used the delineation entirely random, using a factorial arrangement 2 x 3 x 5, with four repetitions, being two for cotton cultivars, two for moisture content (S.0 - seeds with 10%, S.1 - seeds with 8%) and five periods of storage in dry chamber (0, 3, 6, 9 and 12 months). The application laboratory tests were: germination, moisture content and vigour (first counting of germination, seedlings length and precocious aging). The results show that the quality of the cotton seed was superior in the seeds with tenor of 10% of humidity of variety BRS Green throughout the storage, in the different analyzed laboratory tests.
