Abstract
Summary Storage of peanut is increasingly becoming important both among growers and users of the crop in Nigerian savanna. The aim is to sell the produce and maximize benefits accruing from the crops during scarcity. Very often, these envisaged advantages fail due to unfavourable market forces, thus compelling them to sell at a loss or store them across seasons for periods ranging from one to two years. However, information on fungi associated with storage of such peanuts in Nigerian savanna and its attendant problems are yet to be investigated. Thus, the seed mycoflora and viability seven common peanut cultivars stored under conditions similar to traditional settings were investigated using different isolating techniques. The peanut cultivars were RMP 12, RMP 91, RRB, 48-115B, M554-76, 55-437 Ex-Dakar and a local cultivar. None of these cultivars possessed resistance to in vitro colonization by fungi. Aspergillus niger, Aspergillus flavus and Rhizopus stolonifer were consistently isolated from all the cultivars from almost all isolating techniques. Other fungi were Fusarium chlamydosporium, F. roseum, F. oxysporium, Penicillium spp., Curvularia spp., Botryodiplodia theobromae, Macrophomina phaseolina and Sclerotium rolfsii. Relative percentages, however, varied with individual fungi and peanut cultivars. The test with seven different types of growth media gave the highest fungi recovery rate than the blotter paper technique. Seed viability was lower with peanut seeds stored for two years. Also, the relative percentage occurrence of individual fungi was significantly higher with seeds stored for two years. While we recommend the use of growth media for recovery and study of seed mycoflora, peanut seeds should not be stored for more than one year. Resume
