Genome-Wide Association Mapping of Complex Traits in Rice
In rice varieties, there are many naturally occurring genetic variations. Most of morphological, developmental, and physiological variations in rice belong to complex quantitative traits controlled by dozens of genetic variants. One of the most important aims in rice genetic studies is to identify individual genes and their allelic mutations underlying some phenotypic variations in rice through the way of genetic mapping. In this chapter, we begin by addressing the potential difficulties in genetic dissections of complex traits. We then discuss recent progresses on high-resolution quantitative trait locus mapping and genome-wide association study in rice. Finally, some prospects in the future to enhance the mapping power and resolution of complex traits in rice are discussed.
