Therefore, results obtained in barley can be transferred to other Triticeae like wheat. But in contrast to wheat, barley only possesses one genome.
Traits have to be chosen carefully.
The way, there are observed, has an extremely high influence on the result of the analysis. The better defined the analytical question, the better will be the answer by the QTL analysis. The choice of the parents depends on the aim of the analysis, thereby closely connected to the choice of traits in the analysis. Moreover, the analysis is influenced by the type and size of population. These two factors influence the statistical power of the analysis and interfere with each other.
