Therefore, this study aimed to estimate the parameters of adaptability and stability of strawberry cultivars under LT-protected cultivation using the harmonic mean of the relative perf ormance of genetically predicted values. Seven strawberry cultivars were assessed (‘Dover’, ‘Camino Real’, ‘Ventana’, ‘Camar osa’, ‘Seascape’, ‘Diamante’ and ‘Aromas’) in the agricultural years 2006/7, 2007/8 and 2008/9 in three locati ons in the mountainous region of Espírito Santo State. The experiment was arranged in a randomized block design, with 3 replications and 15 plants per plot. The analysis of devi ance for the yield (ton. ha -1 ) demonstrated that only the effects of genotype and the triple interaction genotype x location x year were significant, which indicates the presence of genetic variability among the cultivars and the inconsistency of the position among the genotypes for combinations of year and location. Considering the selection for yield, adaptability and stability, in LT-protected cultivation, cultivars Camarosa and Aromas are highlig hted for expressing average values that were 22% higher than the overall mean of the cultivars (24.55 ton. há -1 ) in the environments assessed. 2015 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303042425005 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
