Due to lack of suitable selection criteria, the development of highly salt tolerant high yielding varieties in rice remain as an incomplete episode & in this cross road the molecular markers finds appropriate place to be used upon. These are more potential; having better resolution and not gets affected by the changing environment. In the present study efforts were made to tag salt tolerant gene(s) in a F3 mapping of Pokkali X IR 28 with concurrent phenotyping in response to excess salt under artificial condition. The result shows ample polymorphism in respect of 10 decamer primers, which is...

The genetic diversity of 25 improved varieties and four traditional varieties were characterized using a set of 20 well chosen and polymorphic microsatellite (SSR) primer pairs. The SSR markers used were polymorphic (100.0%) and generated the reliable information about the relatedness of the varieties. High values of polymorphism obtained in the characterization were attributed to hypervariability of the microsatellite markers. Among the popular varieties, the mean genetic similarity of 0.38 was observed indicating the wide diversity of the popular varieties. Cluster analysis ...
