In: Journal of Genetic Engineering and Biotechnology 2009.v.7(2)Summary: Genetic variability and phylogenic relationship, among ten Egyptian commercial rice varieties namely Giza 175. Giza 177, Giza 178, Giza 181. Giza 182. Sakha 101, Sakha 102, Sakha103, Sakha 104 and Egyptian Yasmine. were established by using fifty two STMS (Sequence Tagged microsatellites) Markers. A high level of polymorphism (84.6%) revealed on agarose gel by SSRs among the tested genotypes). The varieties were clustered based on their banding patterns, using UPGMA method largely on their genetic background with few exceptions. Molecular profile was established for each variety as a fingerprint using clear and distinct patterns of 28 SSR markes. The profile will be used as a reference for the breeder>s rights and Intellectual Property Rights (IPR) and any other related issues. It will also help in assessment of seed purity for specific varieties. Molecular profiling is also an essential requirement for registering the new rice varieties. The profile could bas used for detection of essentially derived varieties.
