Knowing the physiological potential of seeds under certain conditions and storage periods is essential to ensure their availability with adequate quality, as well as information on more productive genotypes. Thus, this work was carried out to analyze the quality of seeds of different cowpea genotypes stored in bags of multifolium paper in a cold chamber during a period of 48 months and subsequently to evaluate the yield potential in the field. For this, two studies were conducted, both at the Universidade Estadual do Sudoeste da Bahia (UESB), campus of Vitória da Conquista, Bahia, Brazil. The first stage was carried out in the laboratory with seed quality evaluation and the second stage was carried out in the field with evaluation of phytotechnical parameters of the genotypes of plants originated from seeds stored. The treatments consisted of eight genotypes of cowpea, of which five were cultivars (BRS Guariba, BRS Novaera, BRS Tumucumaque, BRS Itaim, BRS Cauamé) and three lines (MNC04-769F-49, MNC04-769F-62, MNC04-795F-159). The main conclusions of both experiments were that the seeds conserved in a cold chamber for 48 months did not suffer depreciation in quality, vigor and germination capacity, as well as the plants originated from these seeds also showed satisfactory yield, especially the line MNC04-769F-62.
