Study of two main approaches-electrophoresis and chromatography as varietal identification methods in rice

Abstract

Rice is a major worldwide crop that cultivated in the most areas of the north of Iran (Mazandaran and Gillan Province). An increase in the assortment of rice varieties is making it progressively more difficult to distinguish between the many cultivars by traditional visual identification methods. The more advanced identification techniques of electrophoresis and chromatography offer an effective solution to this emerging identification dilemma. This paper reviews the application of these two evaluation techniques. An Electrophoresis analysis includes gel electrophoresis and capillary electrophoresis and compares them with a popular chromatography technique, namely reversed-phase, size exclusion anion-exchange high performance liquid chromatography (HPLC). This paper will also include an interpretation of the results. © 2007 Asian Network for Scientific Information.
