Abstract EN
Peanut aflatoxin contamination caused by Aspergillus flavus is a serious constraint for food safety and human health in Senegal.
The present study aimed to identify sources of resistance for A.
flavus colonization and aflatoxin contamination.
Thus, seeds from 67 peanut genotypes were tested under laboratory conditions.
Aqueous conidial suspension of an aflatoxinogenic strain of A.
flavus was used for inoculation in Petri dishes containing ten seeds of each genotype, and data on incidence and severity were recorded.
Total aflatoxin concentration in seeds was determined on 15th day after inoculation using mReader® method.
Results showed a significant (p<0.001) variation of aflatoxin, incidence and severity among the tested peanut genotypes.
Incidence ranged from 0 to 70% with a mean of 20.36 ± 0.8%.
Out of the 67 genotypes, eight showed incidence less than 10%.
Severity ranged from 0 to 44% with a mean value of 8.82 ± 0.45%.
The genotype 12CS_104 showed aflatoxin concentration level in conformity with the European standard (4 ppb).
Out of three clusters revealed by hierarchical classification based on disease incidence and severity, the cluster 1 contained 33 genotypes characterised by low incidence and severity values.
These genotypes can be tested under field conditions to confirm their resistance to A flavus.
