This work had the purpose evaluate physiological quality and incidence of fungi in twelve cowpea seeds cultivars, produced in the state of Ceará, Brazil, in 2005. The physiological quality was evaluated through the germination standard and vigour tests (First germination count) and sanity quality was evaluated through the method paper filter (blotter test) being used four repetitions of 100 seeds. In relation physiological potential of cultivars, it was observed that the cultivars presented low vigour, like Galanjão (0 %), Costela de Vaca (11,49 %) and Parambú (16,6 %). The germination index were low too, except Sempre Verde with 70,33 % the germination of seedlings normal. In respect the incidence of fungi in the seeds, the Fusarium spp. was detected in 0,5 a 0,6 %, Colletotrichum only in Corujinha (0,5 %), Pingo de Ouro 3 (2 %) and Macrophomina phaseolina was detected only in Costela de vaca and Pingo de ouro (0,5 %) and Galanjão (7 %). The incidence of Aspergillus spp. was verified in all you cultivars and Penicillium sp. was detected only in Galanjão, Pingo de Ouro and Costela de Vaca (12 %). Others fungi like Curvularia sp., Phoma sp., Trichoderma sp. and Alternaria sp. were detected in low incidence. The seeds evaluated shown a low physiological quality and the most frequent fungi were those of storage.
