The nine environments refer to sites × crop cycle (crop-year) combinations. There were three sites: San Bonifacio (280 masl), Margaritas (116 masl) and Tululá (220 masl); and three crop cycles: plant cane (harvest season, 2004–05), first (2005–06) and second ratoon crops (2006–07). Of the 14 cultivars tested, 12 are from CENGICAÑA Guatemala (CG and CGSP) and two testers, one cultivar from Canal Point (CP) and one from Puerto Rico (PR).
