“…and leaf spot (Helmithosporium spp.) (Badebo 2013;Gemechu 2018;Gemechu Degete 2021). Insect pests can also impact teff production, especially teff grasshoppers (Aiolopus longicornis, Aiolopus thalassinus), teff shoot flies (Elachiptera simplicipes, Melanochaeta vulgaris, Oscinella nartschukiana), teff red worm (Mentaxya ignicollis), wollo bush cricket (Decticoides brevipennis Ragge), and termites (Macrotermus subhyalinus and Odontotermus spp.)…”

“…Head smudge (Helminthosporium miyakei Nisikado) is arguably the most economically important disease in teff farming, and teff genotypes in collections showed some degree of resistance to it (Gemechu Degete 2021). No complete resistance is yet available for teff rust (Uromyces eragrostidis Tracy), another disease with broad diffusion in Ethiopia (Gemechu 2018;Badebo 2013). Teff rust typically occurs after heading stage, yet causes relatively little grain yield losses as compared to other constraints (Dawit and Andnew 2005).…”

Crop germplasm collections are a key asset to support the resilience and productivity of cropping systems worldwide. In their diversity lays an oftentimes untapped reservoir of alleles that may enable breeding strategies targeting local adaptation, resulting in enhanced performance and higher varietal uptake. In the past five decades, the national genebank of Ethiopia actively collected and conserved thousands of teff (Eragrostis tef) accessions, a staple crop throughout the Horn of Africa at the basis of countless cultural uses and with high market relevance. This review article emphasizes the breeding significance of teff genetic resources, highlighting current challenges in teff farming and improvement that could be addressed further valorising germplasm collections. We collect data generated on the largest teff ex situ collections in the world to discuss opportunities to improve teff tolerance to stress and lodging, as well as to increase its productivity across its cropping area. In doing so, we highlight and critically revise current and past literature tapping in teff diversity to support teff improvement. This review starts providing a summary of teff characteristics, detailing the status and challenges of teff cultivation and breeding. It then follows describing the diversity existing in teff diversity collections and its relevance for teff improvement. The review concludes describing the molecular studies undertook on teff in the past two decades, highlighting the perspectives of molecular breeding for teff. The body of knowledge available on teff shows that there is large potential for improvement of this crop to target smallholder farming systems as well as international markets, and that improvement may start from the large diversity available in teff collections.

“…Some of the diseases such as leaf rust (Uromyces eragrostidis Tracy), head smudge (Helmithosporium miyakei Niskado) and damping off (Dreschlera spp.) have been listed among the most important species in different areas particularly in the west and south west parts of the country [15]. The prevalence and damage inflicted by these diseases and insect pests varies from region to region and shows large seasonal variation, the current status of tef diseases is generally little known.…”

Tef (Eragrostis tef (Zucc.) Trotter), is the major Ethiopian cereal crop which feed peoples The prevalence and damage inflicted by diseases and insect pests varies from region to region and shows large seasonal variation, the current status of diseases is generally little known. Information on the prevalence and status of diseases would be essential to devise sound management options. So, our objective is to assess the status of major tef foliar diseases in central highland area of Ethiopia. Assessment was carried in the major tef producing districts of West Shewa, South-west and North shewa zones of Ethiopia. The assessment done in 2019/2020 main cropping season along the main roads and accessible routes in each survey district, and stops made at every 5-10 km intervals based on vehicles odometers as per tef fields available. We have assessed 35 fields which have the potential to produce tef from three zones. From our assessment the major tef foliar diseases recorded were leaf rust, head smudge and spot blotch. The highest tef leaf rust severity (90S) recorded in north shewa zone Mendida district where as the lowest (0%) recorded in Awaro, Asgori, woliso and Dendi districts from South west shewa zone. The highest head smudge severity recorded in west shewa zone liben jawe district where as the lowest head smudge severity recorded in woliso, wolimera and tokekutaye district. There is no head smudge disease recorded in north shewa zone. From our assessment, we have concluded that tef leaf rust and head smudge are the most economically important diseases. Therefore, it is very crucial to develop management option to mitigate those diseases.
