Genetic characterization of Philippine saba germplasm collection using microsatellite markers

The genetic diversity among 75 Philippine Saba gene bank collections and four non-Saba accessions were analyzed using microsatellite markers or simple sequence repeats (SSRs). Eleven primer pairs were found to be polymorphic across all genotypes and amplified a total of 28 alleles. The discriminatory power of the primers was moderately high with mean polymorphism information content (PIC) value of 0.38. Genetic diversity was measured in terms of heterozygosity, fixation index, and genetic distance. Average gene diversity or expected heterozygosities ranged from 0.09–0.58, with an average of 0....
