Abstract:

Genetic linkage mapping is a key link in genomic research, which is the cornerstone of a wide spectrum of biotechnology applications, including gene localization, map-assisted cloning, and molecular marker-assisted selection in breeding. The paper briefly reviewed the procedure of genetic mapping, types of molecular markers, mapping populations, and research progress in construction of the genetic linkage maps of horticulture plants. Furthermore, the existing problems and the future direction were discussed in this field.
