Abstract Conventional American cultivars of coffee are no longer adapted to global warming. Finding highly productive and stable in different environments without neglecting quality characteristics has become a priority for breeders. In this study, new Arabica F1 hybrids clones were compared conventional varieties seven contrasting environments, yield, rust incidence volume the canopy. The was assessed through size, weight 100 beans, biochemical analysis (24 aroma precursors 31 volatiles...
Abstract The coffee research community has maintained a long ongoing debate regarding the implications of shade trees in production. Historically, there been contrasting results and opinions on this matter, thus recommendations for use (namely agroforestry systems) are often deemed controversial, particularly due to potential yield declines farmers’ income. This study is one first demonstrating how several Coffea arabica cultivars respond differently with respect yield. By standardising more...
Abstract Background The fruity aromatic bouquet of coffee has attracted recent interest to differentiate high value market produce as specialty coffee. Although the volatile compounds present in green and roasted beans have been extensively described, no study yet linked varietal molecular differences greater abundance specific substances support aroma specificity coffees. Results This compared four Arabica genotypes including one, Geisha Especial, suggested generate Formal sensory...
In the present paper, we evaluated implementation of a seed production system based on exploitation male sterility coffee. We studied specifically combination between CIR-SM01 and Marsellesa® (a Sarchimor line), which provides hybrid population called Starmaya. demonstrated that establishment garden under natural pollination is possible produces sufficient amount seeds to be multiplied efficiently economically. As expected for F1 hybrid, performances Starmaya are highly superior conventional...
Cocoa cultivation is labeled as a driver of both deforestation and reforestation, yet the extent phenomena varies at farm landscape level response to national local contexts. In this study, we documented main pathways contexts behind cocoa in two sites with different histories cultivation. We combined official statistics, land-use trajectory, satellite imagery, Q-analysis explore discourses country experts Nicaragua Peru. The Q-statements were based on an analysis set legal, institutional,...
A network of agronomists, researchers, and practitioners associated with cacao farming provided open access to their independent field trials across Latin America the Caribbean (LAC). centralized dataset was assembled using qualitative quantitative data from 25 experimental (hereafter referred as “CacaoFIT”) spanning several LAC agroecosystems. This used document main traits agroclimatic attributes cultivation model being tested within CacaoFIT network. By synthesizing an entire trials, this...
Cocoa attainable yields are affected by a complex of pests and diseases in particular agro-environment. Estimation yield loss is critical for agronomic economic decision-making at the farm level. For over 15 months, we monitored 1100 pods from six cocoa clones (PMCT-58, CC-137, CATIE-R1 CATIE-R4, ICS-95, CCN-51) to assess incidence elucidate their survival behavior. grow 12-year timber-based agroforestry plot (1330 plants ha -1 , 100 shade trees 65% cover), La Montaña, Turrialba, Costa Rica....

Introduction. Genetic diversity, registration, and traceability of cacao planting material are the essential tripod to support its sustainable cultivation. In Nicaragua, cocoa is mostly obtained from seeds, which leads great variability in yield, bean quality, tolerance pests diseases. Farmers, technical staff, development projects, investors depend on a limited supply elite trees as reliable source genetic new fronts meet market quality standards. Therefore, national improvement program...
