Climate change causes increasing the salinity crisis of arable land in the world. It is crucial to
develop salt tolerant genotypes that can maintain optimum yield levels. Therefore, the aim of
this study was to discover prospective genotypes tolerant to salinity by using Microsatellites/
Simple Sequence Repeats (SSR) primers. Selection for salinity tolerant genotypes of rice based
on phenotypic performance alone is less reliable and will delay progress in breeding. Recent
advents of molecular markers have been used in selecting salt tolerant rice genotypes. A total
of 13 Simple Sequence Repeats (SSR) primers were used to identify salinity tolerance in 30
rice genotypes. A total number of 39 alleles were detected. The number of alleles per locus
ranged from 3 to 6 with an average of 4.3. The Polymorphism Information Content (PIC) values
ranged from 0.. View More»
