Assessing genetic diversity and population structure in a Dipteryx alata germplasm collection utilizing microsatellite markers

Abstract Dipteryx alata Vogel (Leguminosae) is a native Neotropical tree with a wide distribution in the Brazilian Cerrado that is commonly known as the baru tree. The genetic diversity of 150 D. alata progeny from a germplasm collection was characterized using nine microsatellite markers. Genetic diversity analysis detected 50 alleles ranging from 2 to 14 alleles per locus. The genetic differentiation among populations (θ p = 0.097) suggests moderate genetic structuring and high genetic differentiation among progenies (θ s = 0.169). The intrapopulation index (f = 0.122) indicates the presen...
