Technical Abstract: This chapter describes differences in oat varieties that can be exploited to identify specific varieties or genotypes. Variety identification can be important for seed producers, millers, and even livestock feeders, because of quality characteristics associated with specific varieties. Commonly used methods of variety identification include isozyme analysis and seed protein electrophoresis. Reversed-phase high performance liquid chromatography (RP-HPLC) has been shown to differentiate among varieties, but has not been adopted. Emerging technologies for identifying DNA polymorphisms, such as restriction fragment length polymorphisms (RFLPs) and randomly amplified polymorphic DNAs (RAPDs) are beginning to be used for oat variety identification. Conventional methods, such as seedling analysis for disease reaction, microscopy and image analysis, and cytology can aid in variety identification, but these characteristics usually are not unique to specific varieties.
