Climate change (CC) is already impacting Arabica coffee cultivation in the intertropical zone. To deal with this situation, it is no longer possible to manage this crop using industrial agriculture techniques, which has been the main strategy implemented since the Green Revolution. Developing a more sustainable agriculture system that respects people and the environment is essential to guarantee future generations’ access to natural resources. In the case of Arabica coffee, the solution has been found. Agroforestry is proposed as an ecosystem-based strategy to mitigate and adapt to CC. At least 60% of Arabica coffee is produced in agroforestry systems (AFSs), which are the most sustainable way to produce coffee. Nevertheless, AFS coffee cultivation is currently uncompetitive partly because all modern varieties, selected for full-sun intensive cropping systems, have low yields in shaded environments. Here we review the reasons why agroforestry is part of the solution to CC, and why no breeding work has been undertaken for this cropping system. Based on the literature data, for breeding purposes we also define for the first time one possible coffee ideotype required for AFS coffee cultivation. The four main traits are: (1) productivity based on F1 hybrid vigor, tree volume and flowering intensity under shade; (2) beverage quality by using wild Ethiopian accessions as female progenitors and selecting for this criterion using specific biochemical and molecular predictors; (3) plant health to ensure good tolerance to stress, especially biotic; and (4) low fertilization to promote sustainable production. For each of these traits, numerous criteria with threshold values to be achieved per trait were identified. Through this research, an ecosystem-based breeding strategy was defined to help create new F1 hybrid varieties within the next 10 years.

“…Collectively, our results suggest that future coffee efforts should be focused on exploring the hybrid vigor between both botanical groups but assisted by molecular breeding. In C. arabica , for example, a first generation of hybrids was developed between 1990 and 2013 by a consortium of research and coffee organizations (Turreira, 2022). Designed as crossbreeding between phylogenetically distant cultivars from American and wild cultivars from Africa, the hybrids gained popularity among growers in Central America because the high production, cup quality, and resistance to pests and diseases (Turreira, 2022; Van der Vossen et al., 2015).…”

For C. canephora , we proposed a reciprocal recurrent selection scheme integrated with marker‐assisted selection, where crosses between “Robusta” and “Conilon” pools are explored and the best inter‐specific hybrids are considered for product development or population improvement (Figure 6).…”

Genomic‐assisted breeding for climate‐smart coffee

et al. 2023

Coffee is a universal beverage that drives a multi‐industry market on a global basis. Today, the sustainability of coffee production is threatened by accelerated climate changes. In this work, we propose the implementation of genomic‐assisted breeding for climate‐smart coffee in Coffea canephora. This species is adapted to higher temperatures and is more resilient to biotic and abiotic stresses. After evaluating two populations, over multiple harvests, and under severe drought weather condition, we dissected the genetic architecture of yield, disease resistance, and quality‐related traits. By integrating genome‐wide association studies and diallel analyses, our contribution is four‐fold: (i) we identified a set of molecular markers with major effects associated with disease resistance and post‐harvest traits, while yield and plant architecture presented a polygenic background; (ii) we demonstrated the relevance of nonadditive gene actions and projected hybrid vigor when genotypes from different geographically botanical groups are crossed; (iii) we computed medium‐to‐large heritability values for most of the traits, representing potential for fast genetic progress; and (iv) we provided a first step toward implementing molecular breeding to accelerate improvements in C. canephora. Altogether, this work is a blueprint for how quantitative genetics and genomics can assist coffee breeding and support the supply chain in the face of the current global changes.

“…Plant protection of food crops is precarious and temperature‐dependent infection risks are predicted to put increasing pressure on farmers globally in the coming years (Chaloner et al, 2021). While new coffee hybrids and cultivars are being continuously bred for improved traits such as pest and disease resistance (Bertrand et al, 2021), farmer adoption has historically been low due to the perennial nature of the crop, price and other cultural preferences (Meressa & Navrud, 2020; Turreira‐García, 2022). Given this, NGT for coffee cultivation challenges must accommodate the long production cycles as well as low economic resources of the coffee farmer.…”

“…For this reason, perennial crops like coffee present themselves as an “Achilles heel” to traditional plant breeding and/or NGT (also termed NBT, new breeding technologies). What is more, when renovation is considered, traditional coffee varieties tend to be highly favoured over newly developed hybrid cultivars due to accessibility or cultural preferences by the farmer (Turreira‐García, 2022), family (when cross‐generational) or the influence of nearby neighbours (Diro & Erko, 2019). This might explain why recent data show that even when new coffee hybrids prove to be more productive and resistant to disease or pathogens, less than 5% are adopted for renovation on coffee farms in Latin America annually (Etienne et al, 2021).…”

Around 2 billion cups of coffee are consumed daily, worldwide (Reay, 2019). However, the coffee plant is under threat due to its vulnerability to a plethora of plant pests and diseases, exacerbated by climate change (Avelino, ten Hoopen, et al., 2012;Kumar et al., 2016).In fact, the typical coffee farmer faces a diverse onslaught by an assortment of beetles, bacteria, fungi and nematodes in just one production season (Waller et al., 2007). Traditional chemical pesticides (i.e., insecticides and fungicides) have been a mainstay of the Green Revolution, and thus commonly deployed in coffee production. With more than 470 licensed products approved for use in Brazil alone (Coelho et al., 2019), these agrochemicals are being used as a primary means of management in the onset of pests and diseases across all agricultural sectors including coffee (
