Abstract. Afandi A, Subandiyah S, Wibowo Hieno Afandi, Loekito Suga H, Kageyama K. 2021. Population genetics analysis of Phytophthora nicotianae associated with heart rot in pineapple revealed gene flow between populations. Biodiversitas 22: 3342-3348. has caused pineapple. This study identified the population genetic diversity P. nicotianae, collecting 90 isolates from plantation sites three provinces Indonesia and, as comparisons, seven non-pineapple sites. Six polymorphic microsatellite markers amplified non-coding region was used to characterize diversity. The phylogenetic tree constructed by MEGA major clades; first and second clades were dominated sites, third clade contained allelic pattern using Genalex software local alleles specific Lampung Blitar AMOVA genotypes data showed that had a low among (6%) but high within individual. Conclusively, geneflow
