Diversity analysis of Philippines bananas using simple sequence repeats markers

Issue Date

4-2011

Abstract

Simple Sequence Repeats (SSRs) were used to determine the genetic variability and relationship among sixty-one genotypes of Philippine bananas. Ten out of twelve primer pairs tested were found to be polymorphic and generated 43 alleles ranging from 3 to 13 alleles per primer. Seven out of ten primers gave unique bands for some of the genotypes tested showing their potential use in cultivar identification and fingerprinting. The resolving power of molecular markets measured as the Polymorphism Information Content (PIC) ranged from 0.68 to 0.94. Cluster analysis at the 83.1% similarity divided the dendrogram into 11 cluster with several outliers separated the genotypes of Musa acuminata from other genotypes with different Musa genotypes. Cluster analysis separated the genotypes of Musa acuminata from the other genotypes with A and B genomes although no cohesive clustering among different groups. (i.e. diploids, and tetraploids) was observed.
