Variability and genetic structure in fragments of Eugenia involucrata De Candolle established through microsatellite markers

ABSCTRACT: Eugenia involucrata DC. is a forest species with high environmental and economic potential. The objective of this study was to quantify the genetic variability analyzed structure three natural fragments located in central region Rio Grande do Sul state, Brazil. We used four microsatellite loci developed for congener uniflora using GenAlEx 6.5 software, parameters its partition among within were estimated each locus. observed levels (3.67 alleles per locus; HO = 0.815; HE 0.625; FIS ?0.294), most which (93%) distributed fragments, suggesting that these individuals came from single original population. Gene flow between (2.35 4.56 migrants generation), resulting low differentiation indexes (FST values ranging 0.052 0.096). showed variability, remnants themselves, differentiation. Our results have repercussions planning locally adapted germplasm collections restoration programs, thereby avoiding implantation populations an exogamous depression.
