A cultura dos citros atingiu, nas condicoes brasileiras, altos niveis de tecnologia, que vem sendo aplicados desde a producao de mudas, passando pelo desenvolvimento e conduzindo a elevadas producoes agricolas A crescente utilizacao de material genetico bem caracterizado e livre de patogenos, aplicacoes de defensivos e controle integrado de pragas,fertilizacoes, irrigacao, podas, herbicidas e o uso de reguladores vegetais tem possibilitado economicidade e altos rendimentos. Quando o sistema de producao da cultura maximiza a utilizacao de insumos e tecnologia, torna-se necessario conhecer a fisiologia da planta, para incrementar ainda mais a produtividade. |

The most popular beverage worldwide, coffee, is responsible for a billionaire market chain with arabica coffee leading the production. Coffee breeding programs are focusing on high yield, excellent beverage quality, and disease resistance, but the bienniality comes to a challenge to overcome bean production. The bienniality, the seasonal variation between high and low yielding, is a genetically controlled physiological event that affects yield stability in arabica coffee. However, there are no studies on the best strategies to implement genomic selection in coffee, including how to establish training populations and deal with the biennially. Thus, the objective was evaluated the potential of genomic selection applied to arabica coffee, with particular consideration on how to estimate bienniality effect on genomic prediction accuracy for yield. The population (n = 586) high-density genotyped by GBS was measured in the low (2005 and 2007), and high (2006 and 2008) yield years. The genomic prediction models were established considering genotype and genotype × year effects. Different prediction scenarios were proposed, considering single-year training sets and grouping the data according to bienniality. Overall, training genomic models on biennium of successive years, and predicting the following biennium appears to be the most effective strategy between all tested scenarios. The comparison of phenotypic and prediction approaches revealed an increased selection response using genomic selection, mainly due to the reduced time per breeding cycle. These results can shed light on the implementation of a genome-based selection of arabica coffee and lead to more efficient breeding strategies.
