Description In four rainy seasons (1977-1980) 40 groundnut genotypes were screened for field resistance to Aspergillus flavus. Significant varietal differences were observed at harvest in levels of seed infestation by A. flavus. Field resistances were positively correlated with previously measured resistance to in vitro seed colonization by A. flavus in laboratory inoculation tests. The commercial variety 55-437 had high levels of resistance to A. flavus while two other varieties 73-30 and 73-33 also grown in Senegal had moderate levels of resistance. Genotypes with seed resistance to A. flavus had a lower proportion of A. flavus in their rhizosphere mycoflorae than had genotypes susceptible to seed invasion by this fungus.
