*4.3. Genetic Aspects*

There is a new development in the genetic mapping work. QTLs were identified with di fferent role [76]. QTLs can regulate only visual symptoms, visual symptoms and FDK, FDK and DON and QTLs were identified influencing all three traits. Similar results were published by recent authors [77–81]. This will have the consequence that mapping should be extended to FDK and DON that is generally not done. For the crossing partners, this information is inevitable. From the generally used DI

mapping [17,19,21–25,29,30,32,33,37,56,61], this aspect falls out and has only reduced significance of the QTL identified.
