Study of yellow rust infection on various winter wheat genotypes

Abstract

Winter wheat (Triticum aestivum L.) is our most important cereal. During its production several pathogens can infect the population. In our two-year study susceptibility of 9 winter wheat genotypes against the pathogen Pucciniastriiformis var. striiformis was investigated by three different nitrogen supply levels on a humous sandy soil type. Percentage frequency of yellow rust infection was lower in case of the genotypes Hystar, Mv. Csárdás, Mv. Magdaléna than in case of HK1307, 1304KV, Antonius or Hywin. Based on our results it can be stated that in the crop year 2016 the highest susceptibility towards the pathogen yellow rust was observed for the winter wheat variety GK Csillag. No consequent effect of nitrogen active substance treatments on yellow rust infection could be stated, different applied nitrogen dosages did not affect the infection rate of different genotypes to a statistically verifiable extent.
