Wild potatoes in Costa Rica, 1996

Collectors: D.M. Spooner, R. Hoekstra and B. Vilchez


From November 24 to December 23, 1996, a collaborative collecting expedition was organised by Costa Rica, The United States and The Netherlands to collect wild potato germplasm in Costa Rica and gather field data for taxonomic studies.
Collections were made at 13 sites, 10 of these with mature fruits. The collections considerably extended the numbers and geographic range of the germplasm available from Costa Rica, previously available from only two sites.

In 'Documents' you will find the report of this expedition with a list of collected material. The new samples are listed on page 17-20. Collecting forms have not been used, the collecting data were directly stored on a laptop. Longitude & latitude were recorded by GPS, altitude by an altimeter. Lon/Lat data suffer some inaccuracy, due to deliberate changes by the US military, equivalent to about 100 meters of distance. This "Selective Availability" was turned off in 2000.
