Abstract:
With respect to maize, as one of the most significant agricultural plant species in the world,
resistance to Fusarium is particularly important since chemical control against it is difficult. For
food safety, the National Food Chain Safety Office of Hungary (NFCSO) tests the resistance of
varieties reported for national registration against Fusarium stalk and ear rot (Fusarium spp.). In
this study, we present the results obtained based on the current methodology of resistance test.
Based on the comparison of Fusarium infection of the variety trial set up in 12 different
production sites (Variety Trial Station) in years under test (2014, 2015 and 2016), we test the
effects of the harvest year and trial site based on the rate of infection and the
susceptibility/resistance of 19 hybrids tested for 3 years. There is significant difference between
harvest years, trial sites, and hybrids based on the infection of stalk and ear rot. Based on our
findings, the current methodology can be successfully applied to determining the level of field
resistance. |
