- Abstract
The analysis of oat genetic resources on the mycotoxin production was performed on genotypes grown by experimental field testing with artificial inoculation of Fusarium ssp., within the European project "Avena genetic resources for quality in human consumption" (AVEQ, 2007-2011). The testing of the genetic material was performed in three European countries (Romania, Czech Republic, Germany) by artificial infection with inoculum of Fusarium species: F. culmorum, F. graminearum, F. sporotichioides, F. langesethiae and F. avenaceum. In 2008, in the experimental field of the Suceava Gene Bank, 112 genotypes of oats (modern and obsolete cultivars) originating from different areas of Europe were inoculated, causing Fusarium spp. infection and the presence of DON and T2 mycotoxins. The infection of oat grains with Fusarium spp. was evaluated in the laboratory using three classes of infection: 1- sound, 2- suspiciously infected, grey tips, 3 - Fusarium damaged, discoloured, smaller kernels. Analysis of the mycotoxin content of the tested grains oat accessions was performed by the ELISA immunochemical method in the Agrotest Fyto Laboratory, Ltd., Kromeriz (Czech Republic). The quantification of the obtained results was made by determining the correlation coefficients between the mycotoxin content and the percentage of grains infected with the Fusarium ssp. and different agronomic characters, revealing significant correlations between Fusarium ssp. infection, concentration of DON and T2 mycotoxins, the seed weight, heading and ripening data of tested oat genotypes.
