Abstract

The objective of this study were to assess thelocations contributions in the final testing stage for thesugarcane (Saccharum spp.) Breeding Program in the southeasternregion of Cuba and to identify valuable locations fortesting new genotypes and determine the most productivecultivars at each location. To assess these purpose 15 cultivars,six locations and two crops cycles were evaluated. Data ofcane yield (t cane.ha-1), pol percentage in cane and pol.ha-1were recorded. Results were visualized using Sites Regressionmodel (SREG). Genotype by environment interaction wasdetermined for each location, and variation amongenvironments accounted the major variability for the threeevaluated variables. Combining results obtained from GGEmodel we recommended adding the locations of «Enidio Diaz»and «Dos Ríos» to the «America Líbre» existing one in thefinal testing stage to improve the selection of new cultivars inthe south-eastern region of Cuba.
