Assessment of genetic diversity among moderately drought tolerant landraces of rice using RAPD markers
Genetic diversity and relationships among six rice genotypes were investigated using five random amplified polymorphic DNA (RAPD) markers. A total of 69 alleles were amplified, of which 66 were polymorphic. The size of the amplified alleles was between 0.25 and 2.35 kbp. The number of polymorphic al...

| description | Genetic diversity and relationships among six rice genotypes were investigated using five random amplified polymorphic DNA (RAPD) markers. A total of 69 alleles were amplified, of which 66 were polymorphic. The size of the amplified alleles was between 0.25 and 2.35 kbp. The number of polymorphic alleles detected with each primer ranged from 7 to 24 with an average of 13.2 per primer and the polymorphism information content (PIC) values varied from 0.8672 to 0.9471. Pair-wise similarity estimated the range of 0.308 to 0.718 among all the genotypes and the highest genetic similarity was found between Maloti and BRRI dhan53. Cluster analysis using UPGMA (unweighted pair group method with arithmetic averages) revealed three clusters at genetic similarity of 46%. A moderately drought tolerant landrace, Boalia, formed a single cluster and the remaining genotypes grouped into distinct clusters based on their relatedness. The results showed a high level of genetic diversity among studied genotypes and this information will assist in conservation as well as selection of parents during breeding programs for the development of drought tolerant rice varieties in near future. |
