“…The Coffea genus currently comprises 130 recognized species, but this number rises up to 141 when all the taxa are included [10], most of which are cross-pollinated and distributed in Africa, Madagascar, the Comoros, the Mascarene Islands and Australasia [11,12]. Some of these such as C. liberica, C. dewevrei, C. stenophylla [13], C. mauritiana, C. congensis, C. racemosa, C. zanguebariae, C. bengalensis, C. travancorensis, C. wightiana [14], C. eugenioides and C. humblotiana are or were consumed in the past, then abandoned for various reasons [15].…”

The wild species of the Coffea genus present a very wide morphological, genetic, and biochemical diversity. Wild species are recognized more resistant to diseases, pests, and environmental variations than the two species currently cultivated worldwide: C. arabica (Arabica) and C. canephora (Robusta). Consequently, wild species are now considered as a crucial resource for adapting cultivated coffee trees to climate change. Within the Coffea genus, 79 wild species are native to the Indian Ocean islands of Comoros, Mayotte, Mauritius, Réunion and Madagascar, out of a total of 141 taxa worldwide. Among them, a group of 9 species called "Baracoffea" are particularly atypical in their morphology and adaptation to the sandy soils of the dry deciduous forests of western Madagascar. Here, we have attempted to shed light on the evolutionary history of three Baracoffea species: C. ambongensis, C. boinensis and C. bissetiae by analyzing their chloroplast and nuclear genomes. We assembled the complete chloroplast genomes de novo and extracted 28,800 SNP (Single Nucleotide Polymorphism) markers from the nuclear genomes. These data were used for phylogenetic analysis of Baracoffea with Coffea species from Madagascar and Africa. Our new data support the monophyletic origin of Baracoffea within the Coffea of Madagascar, but also reveal a divergence with a sister clade of four species: C. augagneurii, C. ratsimamangae, C. pervilleana and C. Mcphersonii (also called C. vohemarensis), belonging to the Subterminal botanical series and living in dry or humid forests of northern Madagascar. Based on a bioclimatic analysis, our work suggests that Baracoffea may have diverged from a group of Malagasy Coffea from northern Madagascar and adapted to the specific dry climate and low rainfall of western Madagascar. The genomic data generated in the course of this work will contribute to the understanding of the adaptation mechanisms of these particularly singular species.

Coffee, which is the most popular soft drink in the world, belongs to the genus Coffea in the Rubiaceae family. About 124 species are known in this genus, whereas Coffea arabica L. and Coffea canephora are the two most widely cultivated species worldwide. Coffea arabica is the only tetraploid species in the genus coffea and is self-fertile, while other species are diploid and generally self-incompatible. Ethiopia is the center of origin and diversity for arabica coffee, which is the only species cultivated in the country. The availability of wide genetic variability among the indigenous coffee and the diverse agro-ecologies in the country provided immense possibilities to improve the crop for desirable agronomic and breeding interest traits. Cognizant of this and the occurrence of coffee berry disease (CBD) in Ethiopia for the first time, a coffee breeding program was initiated in the 1970’s aiming at exploiting the available genetic diversity and developing productive varieties combining disease resistance, best quality, and other desirable characteristics. Coffee genetic resource collection, characterization, evaluation, conservation and genetic studies are among the major breeding activities undertaken so far by designing and implementing different breeding strategies following the conventional breeding approach. So far, outstanding achievements have been recorded in collecting 7130 germplasm accessions, generating basic information on the genetics aspects, and developing 44 improved varieties of which seven are F1 hybrids and identifying 149 elite promising genotypes for further evaluation to develop and release a new varieties. Extensive collection of coffee genetic resources from unaddressed areas, and application of molecular breeding techniques such as marker-assisted selection and breeding for stress tolerance, among others, would be the main focus areas of future coffee breeding programs.

“…15 The Coffea Biological Resources Center (BRC Coffea), maintained on Reunion Island, is the result of numerous prospecting and campaigns in Africa (Cameroon, Ivory Coast, Ethiopia, Guinea, Kenya, Central African Republic (CAR), Republic of Congo, Tanzania), with the participation or support of national agronomy research centres and international institutions over a period from the 1960s to the 1980s. To date, the BRC Coffea collection houses 35 Coffea species 16 (http:// florilege.arcad-project.org/fr/crb/coffea). Thanks to the availability of genetic resources at BRC Coffea, which includes species sourced in Cameroon, we were able to conduct the study reported here.…”

Potential beverage quality of three wild coffee species (Coffea brevipes, C. congensis and C. stenophylla) and consideration of their agronomic use

BACKGROUND: Of the 130 known coffee (Coffea) species, very few have been properly evaluated for their beverage quality. The diversity of wild coffee species is considered critical to the long-term sustainability of the coffee sector, particularly under climate change. The challenge is finding coffee crops that satisfy agronomic criteria, now and under the altered climatic conditions of the future, as well as consumer requirements for flavour. We evaluated the sensory characteristics of three wild coffee species with four independent sensory panels, and the key environmental/agronomic requirements of these wild species based on a literature review. RESULTS: Coffea congensis and C. stenophylla have a lower unroasted seed weight compared to C. arabica and C. canephora, while C. brevipes has the largest. Sensory analysis showed that the main differences between species was for the fruitiness attribute. Coffea stenophylla was the fruitiest wild species, and was considered an Arabica-like coffee. The flavour profile range of C. stenophylla covers herb-like, vegetal, floral and fruit; C. brevipes resembles C. stenophylla in some respects. Opinions concerning C. congensis were contradictory and several judges considered the industry-standard coffee flavour wheel not suitable for the beverage produced from this species.CONCLUSION: The three wild species have the required sensory qualities for commercialization. According to published data, C. stenophylla has agronomic potential, especially in warmer climates than Arabica areas. Coffea brevipes and C. congensis have the potential to be easily crossed with C. canephora to form interspecific hybrids capable of adapting to different climatic and agronomic conditions.
