In both season types, eight commercial fungicides were applied and three wheat varieties with differing Fusarium resistance were tested. In the epidemic year, the average total amount of WSC was above 1.6% which was 2 times higher than in the non-epidemic year (0.7%). Sucrose, maltose, raffinose and fructan components determined the increased WSC value, but the most substantial change was observed in maltose content where its average amount was 28 times higher in the epidemic year. Fungicide application also significantly increased all the carbohydrate components except maltose, where significant reduction was observed. WSC components had strong correlation with several farinograph or extensograph parameters, but only the maltose content showed positive strong correlation (r = 0.9) with deoxynivalenol (DON) toxin that was highly affected by the applied fungicide. The changes of WSC indicate altered carbohydrate synthesis along with abnormal degradation processes and thus have impaction on the baking features. It seems that the sugar metabolism interacts with DON synthesis and the results give important additional information to the altered metabolism of the attacked plant.}, year = {2023}, eissn = {2077-0472}, orcid-numbers = {Szekeres, András/0000-0003-1651-4623} } @{MTMT:33741865, title = {A kék szemszínű búza antocianin tartalma és sütőipari minősége}, url = {https://m2.mtmt.hu/api/publication/33741865}, author = {Berényi, Attila and Óvári, Judit and Ács, Péterné Erika and Mihály-Langó, Bernadett and Matuz, János}, booktitle = {Műszaki, technológiai és gazdasági kihívások a 21. században}, unique-id = {33741865}, year = {2023}, pages = {11-12} } @{MTMT:33273059, title = {Őszi búza korai generációs nemesítési törzseinek elemzése}, url = {https://m2.mtmt.hu/api/publication/33273059}, author = {Papp, Mária Erzsébet and Óvári, Judit and Matuz, János and Pauk, János and Purnhauser, László and Fónad, Péter and Mesterházy, Ákos and Beke, B. and Tóth, Beáta and Bóna, Lajos and Takács, T. and Mihály, Róbert and Cseuz, László}, booktitle = {XXVIII.

In this study, 18–23 commercial hybrids were tested between 2014 and 2021. Natural infection from Fusarium spp. was higher than 1.5%, and for Aspergillus spp. this was normally 0.01% or 0, much lower than would be considered as severe infection. In spite of this, many hybrids provided far higher toxin contamination than regulations allow. The maximum preharvest aflatoxin B1 was in 2020 (at 2286 μg/kg), and, in several cases, the value was higher than 1000 μg/kg. The hybrid differences were large. In Hungary, the presence of field-originated aflatoxin B1 was continuous, with three AFB1 epidemics in the 8 years. The highest DON contamination was in 2014 (at 27 mg/kg), and a detectable DON level was found in every hybrid. FUMB1+B2 were the highest in 2014 (at 45.78 mg/kg). At these low infection levels, correlations between visual symptoms and toxin contaminations were mostly non-significant, so it is not feasible to draw a conclusion about toxin contamination from ear rot coverage alone. The toxin contamination of hybrids for a percentage of visual infection is highly variable, and only toxin data can decide about food safety. Hybrids with no visual symptoms and high AFB1 contamination were also identified. Preharvest control, including breeding and variety registration, is therefore of the utmost importance to all three pathogens. Even natural ear rot and toxin data do not prove differences in resistance, so a high ear rot or toxin contamination level should be considered as a risk factor for hybrids. The toxin control of freshly harvested grain is vital for separating healthy and contaminated lots. In addition, proper growing and storage conditions must be ensured to protect the feed safety of the grain.}, year = {2022}, eissn = {2309-608X}, pages = {1-27}, orcid-numbers = {Mesterházy, Ákos/0000-0002-8090-9219; Nagy, Zoltán/0000-0003-2034-9333; Szabó, Balázs/0000-0002-4980-4320} } @article{MTMT:33066354, title = {Novel Insights into the Inheritance of Gibberella Ear Rot (GER), Deoxynivalenol (DON) Accumulation, and DON Production}, url = {https://m2.mtmt.hu/api/publication/33066354}, author = {Mesterházy, Ákos and Szabó, Balázs and Szél, Sándor and Nagy, Zoltán and Berényi, Attila and Tóth, Beáta}, doi = {10.3390/toxins14090583}, journal-iso = {TOXINS}, journal = {TOXINS}, volume = {14}, unique-id = {33066354}, issn = {2072-6651}, abstract = {Gibberella ear rot (GER) is an important fungal ear pathogen of maize that causes ear rot and toxin contamination. Most previous works have only dealt with the visual symptoms, but not with the toxins of GER. As food and feed safety rankings depend on toxin contamination, including deoxynivalenol (DON), without toxins, nothing can be said about the risks involved in food and feed quality. Therefore, three susceptible, three medium-susceptible, and three medium-resistant mother lines were crossed with three testers with differing degrees of resistance and tested between 2017–2020. Two plot replicates and two fungal strains were used separately. The highest heterosis was found at the GER% with a 13% increase across 27 hybrids, including 7 hybrids showing negative heterosis (a higher hybrid performance above the parental mean), with a variance ranging between 63.5 and −55.4. For DON, the mean heterosis was negative at −35%, and only 10 of the 27 hybrids showed a positive heterosis. The mean heterosis for DON contamination, at 1% GER, was again negative (−19.6%, varying between 85% and 224%). Only 17 hybrids showed heterosis, while that of the other 17 was rated higher than the parental mean. A positive significant correlation was found only for GER% and DON; the other factors were not significant. Seven hybrids were identified with positive (2) or negative (5) heterosis for all traits, while the rest varied. For DON and GER, only 13 provided identical (positive or negative) heteroses. The majority of the hybrids appeared to diverge in the regulation of the three traits. The stability of GER and DON (variance across eight data sets) did not agree—only half of the genotypes responded similarly for the two traits. The genetic background for this trait is unknown, and there was no general agreement between traits. Thus, without toxin analyses, the evaluation of food safety is not possible. The variety in degrees of resistance to toxigenic fungi and resistance to toxin accumulation is an inevitable factor.}, keywords = {MAIZE; resistance to Gibberella ear rot; heterosis for Gibberella ear rot; inheritance of the resistance to toxin accumulation; DON-producing intensity}, year = {2022}, eissn = {2072-6651}, orcid-numbers = {Szabó, Balázs/0000-0002-4980-4320; Nagy, Zoltán/0000-0003-2034-9333} } @article{MTMT:32889575, title = {A Fajtaminősítés Kérdése Gabonafélékben Toxikus Gombákkal Szemben.
