Correlation between maize genotypes and the stalk rot caused by maize Fusarium
Acta Agronomica Hungarica 55 (4), 447-452
Abstract: Six single-cross hybrids and their parental lines were inoculated with the FG36 Fusarium graminearum isolate in 2005 and 2006. In both years the degree of infection increased after artificial inoculation for both the hybrids and the inbred lines compared with the level of natural infection. The more severe stalk infection recorded in 2005 than in 2006 could be attributed to the weather conditions during flowering and harvesting.The 18 genotypes examined exhibited different levels of resistance to fusarium stalk rot. It could be concluded from the results that the resistance level of the female parent was decisive in the inheritance of the response to fusarium stalk rot (female component-hybrid r = 0.88, male component-hybrid r = 0.39).Some genotypes may be severely affected in epidemic years, while exhibiting a lower rate of infection in years with lower pathogen pressure. This suggests that successful breeding for resistance can only be carried out efficiently by means of artificial inoculation.
