Influence of various quantitative trait loci (QTL) mapping methods on the mapping accuracy under varying heritability levels

Abstract: ABSTRACT. The study of quantitative trait effects is of great significance for molecular marker-assisted breeding. The accuracy of quantitative trait loci (QTL) mapping is the key factor affecting marker-assisted breeding, and is extremely significant. The effect of different heritability rates (10, 30, 50, 70, and 90%) on the accuracy of QTL mapping of five recombinant inbred lines (RILs) were analyzed via computer simulation. RILs display additive and epistatic genetic effects. The QTLs were analyzed using… Show more

“…Although heritability has a large influence on QTL mapping (Su et al, 2015), heritability determined by the specific quantitative trait itself cannot be altered; thus, researchers cannot increase QTL mapping accuracy by increasing heritability. The marker density of the genetic linkage map is currently thought to be one of most important factors affecting QTL mapping accuracy.…”
