QTL mapping: Methodology and applications in cereal breeding

Abstract

Quantitative trait loci (QTL) mapping in crop plants has now become routine due to the progress made in this area during the last two decades. Although, initial QTL studies mainly focused on the identification of QTLs for only some important quantitative traits (QTs) in any individual crop, QTLs could later be identified for majority of the QTs in each of a number of crops, in many cases leading to cloning of individual QTLs.
