Genomic Selection (GS) has been studied in several crops with potential to increase the rates of genetic gain and reduce the length of breeding cycle. Despite the relevance, there is a modest number of reports applied to the genus Coffea. Nevertheless, the effective implementation depends on the ability to consider genomic models that represent with adequate reliability the breeding scenario in which the specie are inserted. Coffee experimentation, in general, is represented for evaluations in multiples sites and harvests (MET), in order to understand the interaction magnitude and predicting the performance of untested genotypes. Therefore, the main objective of this study was investigate GS models that accommodate MET modeling. A expansion of the traditional GBLUP was proposed in order to accommodate the interactions in the GS model. Different scenarios that mimic the coffee breeding and models commonly used in the analysis were compared. In terms of goodness of fit this approach showed the lowest AIC and BIC values and, consequently, the best goodness of fit. The predictive capacity was measured by cross-validation and, in contrast with the GBLUP, the incorporation of the MET modeling showed higher predictive accuracy (on average 10-17% higher) and lower prediction errors. All the genomic analysis were performed using the Genotyping-by-sequencing (GBS) approach, which showed a good potential to be used in coffee breeding programs. Thus, as conclusion, the results achieved may be used as basis for additional studies into the Genus Coffea and expanded for other perennial crops, that have a similar experimentation design.

Foram avaliados, quanto aos tipos de reação às raças I, II, III e XIII de Hemileia vastatrix, 33 clones de Coffea canephora componentes de variedades clonais, sendo nove com ciclo de maturação precoce da variedade EMCAPA 8111; treze com ciclo de maturação intermediário da variedade EMCAPA 8121 e onze de ciclo de maturação tardio da variedade EMCAPA 8131. Empregou-se escala de notas de 1 a 6, sendo que graus médios de doença menores que 4 corresponderam a reação de resistência e maiores ou igual a 4, de suscetibilidade. Utilizou-se o intervalo de confiança do grau médio de doença como medida de estabilidade de reação dos clones em relação às raças inoculadas. Os clones 154 (precoce), 132, 149 e 201 (intermediários), e, 100 e 143 (tardios) mostraram-se resistentes às quatro raças do patógeno. Entretanto, observou-se variabilidade de reação entre repetições de 12 clones analisados. Os resultados mostraram que as três variedades clonais são constituídas por clones resistentes e suscetíveis às quatro raças do patógeno, indicando a necessidade de estudos mais detalhados, em relação à obtenção de clones com maior nível e durabilidade de resistência à H. vastatrix.
The reaction of 33 clones of Coffea canephora was examined to the races I, II, III and XIII of Hemileia vastatrix. A scale of notes from 1 to 6 was used and values below 4, corresponded to the resistant reaction and larger or equal to 4, susceptiblly. The interval of confidence of the mean of disease was used as a measure of stability of reaction of the clones in relation to the race. The clones 154 (early), 132, 149 and 201 (intermediate), and, 100 and 143 (late) shown resistance to the four races of the pathogen. However, variability in the reation was observed among the 12 analyzed clones. The results showed that the three clonal varieties have resistance and susceptible clones to the four races of the pathogen, indicating the need for more detailed studies, in regard to obtain clones with high level of resistance to H. vastatrix.
