Coffee is a very important product in the State of Espírito Santo, Brazil, and most of it is planted as unshaded coffee monocultures, with few growers managing shaded coffee agroforestry systems (AFS). To analyze the opportunities and challenges associated with coffee agroforestry management, we conducted 58 semistructured interviews with coffee growers. In addition, we conducted a field investigation that tested production of Coffea canephora with the shade trees Australian Cedar (Toona ciliata), Jequitibá (Cariniana legalis), and Teak (Tectona grandis). Of the 58 interviewed farmers, 64% (37) were satisfied with the AFS. One of the main factors that caused satisfaction was obtaining income from sources other than coffee. Unsatisfied farmers mentioned the competition between shade trees and coffee shrubs. Cedar was the shade tree that grew most and reduced coffee production, while the combination with Jequitibá maintained more stable yields. We conclude that the higher the growth rate of trees, the higher the negative impact on the coffee production in the study areas. |

The Coffea canephora germplasm, found in old seed crops in southern EspÃÂrito Santo, Brazil, represents a valuable genetic resource for coffee breeding programs. However, the renewal of these crops by clonal cultivars can narrow down the genetic base. Thus, this study aims to characterize the genetic diversity and population structure of 280 C. canephora genotypes from selected matrices in old (15?46-year-old) seed crops from southern EspÃÂrito Santo using Single Nucleotide Polymorphism (SNP) markers. Out of the 9491 SNPs retrieved from the Diversity Array Technology? sequencing, 2542 high-quality SNPs were used for diversity and population STRUCTURE analyses, which detected two genetic pools. Cluster analysis revealed six clusters, some of which showed a high frequency of expected heterozygotes (HE), an indicative of the genetic diversity (GD) within this population. Clusters 4, 5, and 6, especially, harbor an abundance of heterozygous loci. High FST values were detected between clusters 4 and 2 (0.60), 2 and 5 (0.60), and 4 and 3 (0.50) and between the two genetic pools (0.59). This population?s higher GD indices demonstrate that the old seed crops from southern EspÃÂrito Santo constitute a noticeably rich germplasm bank. This valuable source must be maintained and conserved to ensure coffee crop sustainability since it can broaden the genetic base once reduced by the replacement of crops with clonal cultivars.

Assim, este estudo tem como objetivo caracterizar a diversidade genética e a estrutura populacional de 280 genótipos de C. canephora provenientes de matrizes selecionadas em culturas de sementes antigas (15 a 46 anos) do sul do EspÃÂrito Santo, utilizando marcadores de Polimorfismo de NucleotÃÂdeo Único (SNP). Dos 9.491 SNPs recuperados do sequenciamento Diversity Array Technology?, 2.542 SNPs de alta qualidade foram usados ??para análises de diversidade e ESTRUTURA populacional, que detectaram dois pools genéticos. A análise de cluster revelou seis clusters, alguns dos quais apresentaram alta frequência de heterozigotos esperados (HE), um indicativo da diversidade genética (GD) nesta população. Os clusters 4, 5 e 6, especialmente, abrigam uma abundância de loci heterozigotos . Valores elevados de F ST foram detectados entre os clusters 4 e 2 (0,60), 2 e 5 (0,60) e 4 e 3 (0,50) e entre os dois pools genéticos (0,59). Os maiores ÃÂndices de GD desta população demonstram que as antigas culturas de sementes do sul do EspÃÂrito Santo constituem um banco de germoplasma visivelmente rico. Essa valiosa fonte deve ser mantida e conservada para garantir a sustentabilidade da cultura cafeeira, pois pode ampliar a base genética uma vez reduzida pela substituição de culturas por cultivares clonais.
