An overview of genome-wide association mapping studies in Poaceae species (Model crops: Wheat and Rice)

There is a significant interest while utilizing association mapping technique to determine the genes which are accountable for numerical dissimilarity of the more complex characteristics with agronomic and evolutionary significance. Recently improvements have been made in genomic technology, which motivates for the exploitation of natural diversity, and establishment of more vigorous and strong statistical analysis methods creates association mapping technique more demanding and reasonable to plant research programs. Genome-wide association mapping technique recognizes quantitative trait loci (QTLs) by studying the marker-trait associations which could be credited to the power of linkage disequilibrium between different molecular markers and functional polymorphisms through a pool of diversified germplasm. In this review, we will describe an overview of genetic mapping and the current status of association mapping studies in cereal crops i.e., wheat and rice.
