*2.4.6 Quantitative trait locus mapping*

This can show the position of the identified candidate gene. QTL; the abbreviation for the quantitative trait loci), that can be defined as a genetic locus described by two molecular markers on a genetic map affecting a quantitative trait which is identified in 2 parental lines which differs from each other and are identified in F2 population. The F2 population are evaluated to separate the genetic and environmental effects on the trait in several locations and for years. Later the QTL was mapped to the sector of chromosome [10, 11].
