Abstract

Peanut is of paramount importance in human and animal nutrition, as well as in improving producers’ income. However, its production is faced with abiotic and biotic constraints. Among the biotic constraints, Cercosporiosis diseases are a major handicap in Burkina Faso. In order to minimize the impact of these diseases on peanut yield, important work has been carried out and is still ongoing to select and develop resistant genotypes. This study, carried out in Gampela is aimed at testing the agronomic performance of 30 peanut genotypes from Texas in comparison with a local one (TS32-1). The experiment was carried out using a Fisher (3) repetition block experimental system and the data were processed using XLSTAT pro software. Parameters such as the growth percentage on 15 days after sowing, the survival rate, the severity of the disease and the yield were measured. With respect to Cercosporiosis susceptibility, only the local genotype TS32-1 was sensitive; the genotypes TxL151109-02, TxL151134-02, TxL151148-04, TxL151121-03, TxL151107-01 and TxL151151-01 were moderately resistant.  Only genotype TxL151109-02 had a higher yield (0.36 t/ha) than that of the local one TS32-1 (0.28 t/ha) and the lowest yield was from the genotype TxL151105-05 (0.03 t/ha).
