SNP Genotyping data for Guadeloupean and Haitian coffee trees

The West Indies, particularly former French colonies like Haiti and Guadeloupe, were central to the spread of coffee in the Americas. The histories of these Islands are shared until the XIXth century, where they diverged significantly. Still, both Islands experienced a strong decline in their coffee sector. Characterizing the genetic and varietal diversity of their coffee resources and understanding historical factors shaping them can help support revitalization efforts. To that end, we performed KASP-genotyping of 80 informative SNP markers on field samples from across main coffee-growing region of Guadeloupe, and two historically important ones in Haiti, as well as 146 reference accessions from international collections, and acquired data from published sources. While most samples are Coffea arabica, other species are represented, namely C. canephora, C. liberia, and C. congensis
