“…The country is recognized as the secondary centre of diversity for barley [2], and the Ethiopian barley germplasm has been important worldwide as a source of useful genes for traits such as disease resistance [3,4]. The crop is produced by subsistence farmers mostly grown as landraces with little or no application of fertilizers, pesticides and herbicides [5]. Landraces are defined as traditional varieties developed through natural and human selections, which are named and maintained by traditional farmers to meet their social, economic, cultural, and ecological needs [6].…”

“…Landraces are defined as traditional varieties developed through natural and human selections, which are named and maintained by traditional farmers to meet their social, economic, cultural, and ecological needs [6]. Barley is cultivated from 1400 to over 4000 m above sea level, and its importance increases in drought-prone areas and at higher elevations (above 2800 m) where poor soil fertility, frost, water logging, and soil acidity and degradation are the major yield limiting factors [5,7]. The major barley producing regions in Ethiopia are Oromiya, Amhara and Tigray Regional States, which account for about 87% of the national barley production [1].…”

“…Landraces are considered more locally adapted and genetically variable than modern cultivars [6,10]. They contribute to agricultural production around the world, particularly for the rural poor in marginal environments as source of seed for next season planting [5,10]. Farmers make crop maintenance decisions based on combinations of factors including adaptability, yield, socio-cultural values and food traditions as well as nutritional values.…”

“…With regards to barley, there have been efforts, though limited, on documentation of its utilization and ethno-botany for some parts (e.g. Central) of Ethiopia [5,14-16]. We conducted a study on barley utilization in North Eastern Ethiopia with the main objectives to (1) document the importance, ethnobotany and types of barley landraces grown; (2) investigate and gather information on the utilization of barley and its importance in the diets of the people, and the dishes prepared; (3) examine how barley end-uses influence the maintenance of its landraces.…”

BackgroundBarley is the number one food crop in the highland parts of North Eastern Ethiopia produced by subsistence farmers grown as landraces. Information on the ethnobotany, food utilization and maintenance of barley landraces is valuable to design and plan germplasm conservation strategies as well as to improve food utilization of barley.MethodsA study, involving field visits and household interviews, was conducted in three administrative zones. Eleven districts from the three zones, five kebeles in each district and five households from each kebele were visited to gather information on the ethnobotany, the utilization of barley and how barley end-uses influence the maintenance of landrace diversity.ResultsAccording to farmers, barley is the "king of crops" and it is put for diverse uses with more than 20 types of barley dishes and beverages reportedly prepared in the study area. The products are prepared from either boiled/roasted whole grain, raw- and roasted-milled grain, or cracked grain as main, side, ceremonial, and recuperating dishes. The various barley traditional foods have perceived qualities and health benefits by the farmers. Fifteen diverse barley landraces were reported by farmers, and the ethnobotany of the landraces reflects key quantitative and qualitative traits. Some landraces that are preferred for their culinary qualities are being marginalized due to moisture shortage and soil degradation.ConclusionsFarmers' preference of different landraces for various end-use qualities is one of the important factors that affect the decision process of landraces maintenance, which in turn affect genetic diversity. Further studies on improving maintenance of landraces, developing suitable varieties and improving the food utilization of barley including processing techniques could contribute to food security of the area.

Barley (Hordeum vulgare L.) is an important food security crop due to its high-stress tolerance. This study explored the effects of CO2 enrichment (eCO2) on the growth, yield, and water-use efficiency of Ethiopian barley cultivars (15 landraces, 15 released). Cultivars were grown under two levels of CO2 concentration (400 and 550 ppm) in climate chambers, and each level was replicated three times. A significant positive effect of eCO2 enrichment was observed on plant height by 9.5 and 6.7%, vegetative biomass by 7.6 and 9.4%, and grain yield by 34.1 and 40.6% in landraces and released cultivars, respectively. The observed increment of grain yield mainly resulted from the significant positive effect of eCO2 on grain number per plant. The water-use efficiency of vegetative biomass and grain yield significantly increased by 7.9 and 33.3% in landraces, with 9.5 and 42.9% improvement in released cultivars, respectively. Pearson’s correlation analysis revealed positive relationships between grain yield and grain number (r = 0.95), harvest index (r = 0.86), and ear biomass (r = 0.85). The response of barley to eCO2 was cultivar dependent, i.e., the highest grain yield response to eCO2 was observed for Lan_15 (122.3%) and Rel_10 (140.2%). However, Lan_13, Land_14, and Rel_3 showed reduced grain yield by 16, 25, and 42%, respectively, in response to eCO2 enrichment. While the released cultivars benefited more from higher levels of CO2 in relative terms, some landraces displayed better actual values. Under future climate conditions, i.e., future CO2 concentrations, grain yield production could benefit from the promotion of landrace and released cultivars with higher grain numbers and higher levels of water-use efficiency of the grain. The superior cultivars that were identified in the present study represent valuable genetic resources for future barley breeding.
