Abstract
Rice genetics is the science of studying heredity in rice and related plant species and is the basis for all sound, effective, and efficient breeding programs. Rice traits under genetic study can be assigned to two broad categories as qualitative traits and quantitative traits. While quantitative traits are controlled by many quantitative trait loci (QTLs), each QTL could be dissected as Mendelian factor at molecular level using molecular markers, which could be identified by map-based cloning approach. The current progress made in the genetic basis for the traits of importance in rice has been introduced, focusing the cloning of major genes or finely mapped QTLs. Better understanding of the inheritance of rice traits will stimulate significant progress either in selection efficiency or in accuracy for rice breeding. Genome-wide association studies (GWAS) have emerged as a powerful approach for identifying genes underlying complex traits of rice. Combining GWAS with other functional genomics approaches may facilitate dissecting agronomic traits and identifying the important gene alleles in rice.
