Abstract: The ability to discriminate between rice as well as other crop cultivars is fundamental to the operation of the modern seed industry and trade. A new era of plant variety protection began by enacting the intellectual property rights legislation very recently in Egypt. All sectors of the seed industry from plant breeders through the registration authorities to the seed quality control agency and other end-users benefit from cultivar verification at some stage in their activities. This paper considers some of the methods that are being applied to verification of the 9 rice cultivated varieties which represent all the recommended rice varieties now in Egypt. The International Union for the Protection of New Plant Varieties (UPOV) rice descriptor was used to identify the tested cultivars morphologically; two additional chemical attributes were added to the descriptor. Two DNA profiling techniques were used to characterize the differences between the 9 tested cultivars. Combining the morphological description with the application of different molecular methods in variety identification makes the breeding process and genetic purity maintenance more efficient.
