Asparagus is a perennial crop which remains in production for at least 10 years. Therefore, the appropriate election of cultivars is crucial for asparagus growers. The aim of this work was to determine which environment is most desirable for enhancing asparagus clonal hybrids selection. Thirty four asparagus clonal hybrids and two testers were planted in a complete randomized block design. Total yield was evaluated for each hybrid in four environments conformed by combinations between age of culture and type of production. Data were subjected to an ANOVA and broad sense heritability was calculated for each environment. GGE biplot methodology was also used. The second productive season (for blanched and green production) was the best test environment and the most powerful to discriminate genotypes. Selection in this productive season would reduce time and costs in asparagus cultivars evaluation.
