Abstract
The majority of important agronomic traits in rice are quantitatively inherited in rice. Many quantitative trait loci (QTLs) regulate trait phenotypes in concert, which introduces complexities in genetic analyses. With the advent of molecular markers and construction of genetic linkage maps, QTL mapping has progressed considerably since 1990. Thousands of QTLs have been reported for yield-related traits in rice. Some major QTLs have been cloned on the basis of primary QTL results. The favorable alleles of QTLs can be directly explored in rice breeding through marker-aided selection. The markers linked to target QTLs and functional markers derived from well-characterized genes/QTLs are ideal tools for directional selection owing to their stability and low cost. This chapter will review the progress of rice markers and QTLs over the last 2 decades and evaluate the prospects for the genetic improvement of rice.
