Abstract
Reaction of 10 maize inbred lines against Fusarium verticillioides and fumonisin accumulation were evaluated under field conditions with three replications in Pars Abad-e-Moghan, Iran. For artificial inoculation, the inbred lines were inoculated with spore suspension in concentration of 1 × 106 ml−1 7–10 days after emergence of silk, using nail punch method. To evaluate the development of the disease, its severity percent and grain yield (g plant−1) was determined two months after inoculation. Total fumonisin produced on maize grains were also evaluated by ELISA kits. The results showed inbred lines K19, K19/1 and K74/1 were susceptible and the rest of the inbred lines were moderately resistant to the diseases. Among moderately resistant inbred lines, A679 and K18 had lowest fumonisin accumulation. Average of the fumonisin accumulation under natural infection condition (control) was 3.37 mg kg−1 while it was 29 mg kg−1 under artificial infection condition, which was 760% more than control.
