Evaluation location: Wisconsin, United States
Samples were collected from 97 populations of the wild potato S. stoloniferum (previously fendleri) in the following seven mountain ranges of the southwest USA over 7 years, 2004-2010: Chiricahua (CHI), Huachuca (HUA), Rincon (RIN), Guadalupe (GUA), Pinaleno (PIN), Santa Catalina (CAT), and Santa Rita (RIT). These and previous samples were compared with AFLP markers to determine which ranges have the most genetic richness. A total of 2,079 bands were polymorphic over all populations, and 1,256 were polymorphic among ranges. Of these 1,256 bands, 279 occurred in only one range (= unique). The number of unique bands for each population was determined and noted.
