    Screening for Salinity Tolerance among 30 Rice (Oryza sativa L.) Genotypes Using Microsatellite Markers
    Author(s): Kargbo S.S, Showemimo F.A*, Akintokun P.O and Porbeni J.B.O

    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»
