Abstract
Fungal contamination of maize fields with Fusarium species leads to yield loss and affects grain quality. In this investigation, maize of three genotypes Ku123, RF7, MK01 at the silking, dough and physiological maturity stage were analyzed for mixed contamination with F. verticillioides, F. oxysporum, F.avenaceum. Asymptomatic mixed infection with F. oxysporum, F. verticillioides, F. avenaceum was detected in all samples of Ku123 and in some samples of the genotype RF7. The genotype MK01 was infected only with F. oxysporum. PCR estimation of the number of copies of Fusarium spp by serial dilutions demonstrated that genotype Ku123 is the most susceptible to the infection.
