The evaluation effect of fusarium verticillioides on seed quality in new high-yielding maize vareties

Abstract

Fusarium verticillioides can cause a decrease in the yield and quality of corn due to the mycotoxins produced. 10 seeds high yielding maize varieties were sterilized using a 5.15% NaClO solution and sterile water. Inoculated seeds for 72 hours, grown on straw paper and polybags. Observation of germination, plant growth, incidence and severity of disease as well as the identification of Koch’s Postulates method, were observed macroscopically and microscopically at the Laboratory, Hasanuddin University. The results showed that F. verticillioides caused the germination of maize seeds in the Pertiwi and NK sumo varieties to only 33.3%, while the highest germination occurred in the Sukmaraga variety at 91.7%. The growth of corn plants showed differences in height and number of leaves in each of the 10 varieties. Severity of the disease in the vegetative phase occurred in the variety Pertiwi and Pioneer27 by 35% and the varieties with the lowest severity occurred in Zakarin variety by. Selection of varieties that are resistant to the F. verticillioides pathogen greatly influences F. verticillioides infection because they can be a source of inoculum.
