“…The Coffea spp. crop in Taposontok is susceptible to diseases (rust, cercosporiosis, phoma leaf spot and bacterial blight) and pests favored by climate change [22]. Its different cultivation systems (Rustic, Unshaded Monoculture, Shaded Monoculture, Commercial Polyculture and Traditional Polyculture) have negatively affected coffee cherries' yield related to soil health [3].…”

The cultivation systems of Coffea spp. in a cooperative society in Puebla, Mexico, include Rustic, Traditional Polyculture, Commercial Polyculture, Unshaded Monoculture and Shaded Monoculture. In this work, the properties of the soil were analyzed through physical, chemical and biological analyses to determine its nutritional status. Composite sample analyses were conducted to determine physical, chemical and microbiological parameters (fungi, actinomycetes, mesophilic bacteria, nitrifying and denitrifying bacteria). Leaf nutrients were determined. Rustic was the cropping system with the highest amount of K in the soil and nutrient assimilation in the leaf (N, P, K and Fe) (p = 0.001); in addition, it had high populations of mesophilic bacteria, fungi and actinomycetes and very low nitrification and denitrification rates. The principal component analyses (PCA) (>3.25%) indicated that actinomycetes and K in soil favor the assimilation of Fe, K and P. This Coffea Molina-Monteleón, C.M.; Mauricio-Gutiérrez, A.; Castelán-Vega, R.; Tamariz-Flores, J.V spp. cultivation system generated a lower impact on soil health than the rest of the systems and favored forest ecosystem conservation.

“…Plants can only be directly imported to Hawaii from the continental U.S. and is subject to a one year quarantine. However, under the Code of Federal Regulations, exceptions to coffee plant importations were given with the correspondent permits [56,57]. Basically, all plants imported require importation permits, a U.S. Customs declaration, and examination by Plant Protection and Quarantine Service inspectors.…”

Hawaii has long been one of the last coffee-producing regions of the world free of coffee leaf rust (CLR) disease, which is caused by the biotrophic fungus Hemileia vastatrix. However, CLR was detected in coffee farms and feral coffee on the island of Maui in February 2020 and subsequently on other islands of the Hawaiian archipelago. The source of the outbreak in Hawaii is not known, and CLR could have entered Hawaii from more than 50 coffee-producing nations that harbor the pathogen. To determine the source(s) of the Hawaii inoculum, we analyzed a set of eleven simple sequence repeat markers (SSRs) generated from Hawaii isolates within a dataset of 434 CLR isolates collected from 17 countries spanning both old and new world populations, and then conducted a minimum spanning network (MSN) analysis to trace the most likely pathway that H. vastatrix could have taken to Hawaii. Forty-two multilocus genotypes (MLGs) of H. vastatrix were found in the global dataset, with all isolates from Hawaii assignable to MLG 10 or derived from it. MLG 10 is widespread in Central America and Jamaica, making this region the most probable source of inoculum for the outbreak in Hawaii. An examination of global weather patterns during the months preceding the introduction of CLR makes it unlikely that the pathogen was windborne to the islands. Likely scenarios for the introduction of CLR to Hawaii are the accidental introduction of spores or infected plant material by travelers or seasonal workers, or improperly fumigated coffee shipments originating from Central America or the Caribbean islands.

“…Coffee is a widely consumed beverage that drives a vibrant industry, which contributes significantly to the economies of several tropical and developing countries. Globally, it is estimated that more than 100 million of growers are benefited from the coffee supply chain and over 2.2 billion cups of coffee are consumed daily (Krishnan et al., 2021). Despite this importance, its sustainability is facing critical challenges, including accelerated climate changes, price volatility, limited access to genetic resources, and the presence of new pests and diseases (Davis et al., 2021; Van der Vossen et al., 2015).…”

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.
