Association mapping, a high-resolution method for mapping quantitative trait loci based on linkage disequilibrium, holds great promise for the dissection of complex genetic traits. General understanding of association mapping has increased significantly since its debut in plants. We have seen a more concerted effort in assembling various association-mapping populations and initiating experiments through either candidate-gene or genome-wide approaches in different plant species. In this review, we describe the current status of association mapping in plants, Relation between LD and Association Mapping, QTL Mapping and Association Mapping, Types of Association mapping, Steps in Association Mapping and Benefits and limitations of association mapping. |
