“…Despite the wide distribution of wild enset, enset has been domesticated only in the Ethiopian highlands (Borrell et al, 2019; Heslop-Harrison et al, 2019) and it is now grown as a crop mainly in the southern and south-western parts of Ethiopia (Olango et al , 2014; Guzzon & Müller, 2016). In these regions, cultivated enset is propagated vegetatively from suckers.…”

“…Due to its importance for food security in Ethiopia (Yemataw et al , 2014; Guzzon & Müller, 2016; Yemata, 2020), enset has been called “the tree against hunger” (Brandt et al, 1997a). Enset is known for its high yield, drought tolerance, high shade potential, broad agro-ecological distribution and long storage capacity (Brandt et al, 1997b; Quinlan et al, 2014).…”

“…Enset is known for its high yield, drought tolerance, high shade potential, broad agro-ecological distribution and long storage capacity (Brandt et al, 1997b; Quinlan et al, 2014). Despite these positive features, enset has received little research attention (Borrell et al, 2019) and its genetic diversity is under threat from diseases such as bacterial wilt and from pressures associated with human population growth (Birmeta, 2004; Guzzon & Müller, 2016).…”

23Enset (Ensete ventricosum (Welw.) Cheesman) is a drought tolerant, vegetatively propagated 24 crop that was domesticated in Ethiopia. It is a staple food for more than 20 million people in 25 Ethiopia. Despite its current importance and immense potential, enset is among the most 26 genetically understudied and underexploited food crops. We collected 230 enset wild and 27 cultivated accessions across the main enset producing regions in Ethiopia and applied amplified 28 fragment length polymorphism and genotype by sequencing (GBS) methods to these 29 accessions. Wild and cultivated accessions were clearly separated from each other, with 89 30 genes found to harbour SNPs that separated wild from cultivated accessions. Among these, 17 31 genes are thought to be involved in flower initiation and seed development. Among cultivated 32 accessions, differentiation was mostly associated with geographical location and with 33 proximity to wild populations. Our results indicate that vegetative propagation of elite clones 34 has favoured capacity for vegetative growth at the expense of capacity for sexual reproduction. 35This is consistent with previous reports that cultivated enset tends to produce non-viable seeds 36 and flowers less frequent than wild enset. 37

Enset (Ensete ventricosum (Welw.) Cheesman) is a drought tolerant, vegetatively propagated crop that was domesticated in Ethiopia. It is a staple food for more than 20 million people in Ethiopia. Despite its current importance and immense potential, enset is among the most genetically understudied and underexploited food crops. We collected 230 enset wild and cultivated accessions across the main enset producing regions in Ethiopia and applied amplified fragment length polymorphism (AFLP) and genotype by sequencing (GBS) analyses to these accessions. Wild and cultivated accessions were clearly separated from each other, with 89 genes found to harbour SNPs that separated wild from cultivated accessions. Among these, 17 genes are thought to be involved in flower initiation and seed development. Among cultivated accessions, differentiation was mostly associated with geographical location and with proximity to wild populations. Our results indicate that vegetative propagation of elite clones has favoured capacity for vegetative growth at the expense of capacity for sexual reproduction. This is consistent with previous reports that cultivated enset tends to produce non-viable seeds and flowers less frequently than wild enset.

“…Conservation of enset genetic resources ex situ as seed in cold storage is difficult or even impossible. Guzzon and Müller (2016) surveyed plant genetic resource databases, gene and seed banks, research centres and interviewed individual researchers, but found a seed accession of only one of the enset species (E. ventricosum), in the Millennium Seed Bank of the Royal Botanic Garden, Kew, UK. Seeds of enset landraces cannot be obtained easily and if so, they are difficult to store because of their bulky size, and are hard to germinate.…”

Introduction-Enset is an indigenous crop in southern and southwestern Ethiopia, with a huge potential to provide year-round food production. Starch stored in the corm and pseudostem of the plant is the main source of energy provided by this crop. Enset was fully domesticated in Ethiopia between 10,000 and 5,000 years ago and initially farmed in a system of shifting cultivation. This long history of enset cultivation has contributed to the high withinspecies diversity. Materials and methods-This paper provides an overview of past research activities and knowledge linked to enset diversity and identifies critical research gaps, which should be addressed to improve the long-term conservation and use of this diversity. Results and discussion-Studies have identified numerous landraces across the vast ensetgrowing belt in Ethiopia, with genetic diversity in a particular area related to the extent of enset cultivation by different ethnic groups and the range of agro-ecologies to which the crop is adapted. Farmers' rich knowledge of enset, accumulated over many years, plays a significant role in the characterization and maintenance of the existing genetic diversity of this crop. Farmers differentiate landraces using morphological traits, such as plant height and pseudostem size, angle of leaf orientation, and pseudostem and leaf colour. Conclusion-Enset diversity provides resilience and food security despite challenging environmental conditions, diseases or changes in land use systems.
