In 2020, Dr Angela Alleyne, Senior Lecturer in Biochemistry at the University of the West Indies (UWI), conducted research on 15 varieties of sweet potato across five Caribbean countries, and identified several drought-tolerant varieties under commercial production in Dominica (“SDPW-01” and “SRDY-DOM”), Grenada (“Cricket Gill” and “Hucky”), Jamaica (“Ganja” and “Fire on Land”), and St. Lucia (“SSLYY”). These climate resilient varieties are an excellent choice for production as the region continues to experience more severe dry seasons.

I emailed the Dr. and she said she would find out what variety we have.
