Abstract: Oat (Avena sativa) is an annual grass species grown as either a grain or a forage crop. Its valuable nutrition and excellent forage quality make its market demand increase year by year, which brings forth new requirements for innovative oat cultivars. Molecular breeding is the ideal technology for oat improvement with its high precision and efficiency. Genomic study of oat is the very important basis for the analysis of important agronomic traits, the precise utilization of excellent germplasm and molecular design breeding of oats. This article mainly reviews the important achievements of world-wide oat germplasm resources collection and preservation, genome composition and chromosome ploidy level variations in the genus Avena, oat genetic linkage map construction and oat genome sequencing, as well as oat molecular breeding. Furthermore, this article discusses the future directions of oat genomic study and molecular breeding in the post genomic era.

Key words: oat, genetic linkage map, genome sequencing, molecular breeding
