“…Our observations that cultivated ensets exhibited higher heterozygosity and Shannon's Index than wild enset resemble what have been reported for enset based on SSR markers study (Gerura et al , 2019) and for other plant species, including Camellia sinensis (Yang et al, 2016) and C. taliensis (Zhao et al, 2014). The high heterozygosity of cultivated enset might be due to vegetative propagation maintaining heterozygosity across clonal generations.…”

“…The results presented here indicate that cultivated and wild enset accessions exhibit similar gene diversity and polymorphic information content (PIC) (Table 4). This is similar to what has been reported based on SSR marker analysis of enset genetic diversity (Gerura et al , 2019), but differs from what has been reported by Olango et al (2015), which reported that higher gene diversity in cultivated enset population (0.59) than wild enset population (0.40), but similar hetrozygosity for cultivated and wild enset populatons (0.5). The genetic diversity for both cultivated and wild enset reported in the current study (Table 4) is lower than previous enset genetic diversity studies conducted using SSR makers (Getachew et al , 2014; Olango et al, 2015 ; Gerura et al , 2019).…”

“…Genetic analysis of intraspecific variation in enset has mainly relied upon data for ‘anonymous’ molecular markers, such as amplified fragment length polymorphisms (AFLP) (Tsegaye & Struik, 2002), random amplified polymorphic DNA (RAPD) (Birmeta et al, 2004), inter simple sequence repeats (ISSR) (Tobiaw & Bekele, 2013) and microsatellites (simple sequence repeat (SSR) polymorphisms (Getachew et al , 2014; Olango et al , 2015; Gerura et al , 2019). Given that enset is vegetatively propagated, genetic divergence among cultivars may be minimal (McKey et al, 2010) and could be difficult to detect using these marker types.…”

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

“…According to our results, moderate level of genetic diversity (H e = 0.47) was detected. A relatively higher H e values (0.55 and 0.59 ) of enset were reported [23] and [25,26] respectively. The value of I (0.74) in the current study was also lower as compared to the earlier report (1.08) [25].…”

“…SSR markers are highly polymorphic, co-dominant and the primer sequences are generally well conserved within and between related species [24]. Recently, Gerura et al [25] and Olango et al [26] have reported measurement of genetic diversity of enset using SSR markers. The previous studies were carried out on landraces from speci c locations, and there was no identi cation and diversity study on enset landraces used for traditional medicine, potentially another reservoir of diversity.…”

Background Enset (Ensete ventricosum) is a multipurpose crop extensively cultivated in southern and southwestern Ethiopia for human food, animal feed and fiber. It contributes to the food security and rural livelihoods of 20 million people. Several distinct enset landraces are cultivated for their uses in traditional medicine. Socio-economic changes and the loss of indigenous knowledge might lead to the decline of important medicinal landraces and their associated genetic diversity. However, it is currently unknown whether medicinal landraces are genetically differentiated from other landraces. Here, we characterize the genetic diversity of medicinal enset landraces to support effective conservation and utilization of their diversity Results We evaluated the genetic diversity of 51 enset landraces of which 38 have reported medicinal value. A total of 38 alleles were detected across the 15 SSR loci. AMOVA revealed that 97.6% of the total genetic variation is among individual with an FST of 0.024 between medicinal and non-medicinal landraces. A neighbor-joining tree showed four separate clusters with no correlation to the use values of the landraces. Principal coordinate analysis also confirmed the absence of distinct clustering between the groups, showing low differentiation among landraces used in traditional medicine and those having other use values. Conclusion We found that enset landraces were clustered irrespective of their use value, showing no evidence for genetic differentiation between enset grown for ‘medicinal’ uses and non-medicinal landraces. This suggests that enset medicinal properties may be restricted to a more limited number of genotypes, a product of interaction with the environment or management practice, or partly misreported. The study provide baseline information that promotes further investigations in exploiting the medicinal value of these specific landraces
