Abstract:
Many agriculturally important variations such as productivity and quality, tolerance to environmental stresses, and some of forms of disease resistance are controlled by polygenes. These complex traits are referred to as quantitative trait loci (QTLs), and it is challenging to identify QTLs based on only traditional phenotypic evaluation. Linkage analysis and association mapping are the two most commonly used tools for dissecting complex traits like QTLs. Association mapping examines the linked inheritance of functional polymorphisms and adjacent molecular markers in a set of genotypes with unknown ancestry. Association mapping is also known as linkage disequilibrium mapping as LD is used for association study.
