“…Although the silage materials had similar DM contents, the materials from 100% had probably more tissue moisture from irrigation than the ones that originated from 75% irrigation. The difference in the genotypes could be attributed to the variation among the tef lines selected for the experiment, as tef is also diverse as reported by [3,13,25,[54][55][56]. A higher LAB www.videleaf.com count in HI treatment relative to the other three treatments is most probably because of the LAB component of HI.…”

“…This could be due to lower moisture content leading to better silage fermentation characteristics [67][68][69]. The difference among genotypes could be attributed to the tef diversity reported by [3,13,25,[54][55][56]. The lower WSC contents among treatments www.videleaf.com (0.04 to 0.16 g/100 g DM) and particularly lower in HI and MOL + HI could be attributed to more efficient ensiling where the microorganisms used the sugars as their source of energy.…”

“…High N-NH3 concentrations could depict less efficient fermentation, and lower ones could depict the conversion of the N-NH3 and its derivatives into microbial proteins, which benefits livestock and prevents N wastage [70]. The variation in the N-NH3 concentration could still be attributed to diversity [3,13,25,[54][55][56], whereas the low concentrations in MOL + HI would imply more efficient utilisation of N-NH3 and its derivatives due to the synergy between MOL + HI, as the HI would provide microorganisms for fermentation and molasses would serve as source of available energy. It is also worth noting that there was even more N-NH3 at 100% irrigation during the aerobic stability experiment.…”

“…Over the last two decades, there has been progress in the area of tef genetic architecture and genomics research [ 105 , 106 ] ( Figure 1 ). From a total of 42 improved tef varieties released by the National Research Program in Ethiopia, 18 were developed using the hybridization technique [ 107 ].…”

Tef (Eragrostis tef (Zucc.) Trotter) is a staple food crop for 70% of the Ethiopian population and is currently cultivated in several countries for grain and forage production. It is one of the most nutritious grains, and is also more resilient to marginal soil and climate conditions than major cereals such as maize, wheat and rice. However, tef is an extremely low-yielding crop, mainly due to lodging, which is when stalks fall on the ground irreversibly, and prolonged drought during the growing season. Climate change is triggering several biotic and abiotic stresses which are expected to cause severe food shortages in the foreseeable future. This has necessitated an alternative and robust approach in order to improve resilience to diverse types of stresses and increase crop yields. Traditional breeding has been extensively implemented to develop crop varieties with traits of interest, although the technique has several limitations. Currently, genome editing technologies are receiving increased interest among plant biologists as a means of improving key agronomic traits. In this review, the potential application of clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated proteins (CRISPR-Cas) technology in improving stress resilience in tef is discussed. Several putative abiotic stress-resilient genes of the related monocot plant species have been discussed and proposed as target genes for editing in tef through the CRISPR-Cas system. This is expected to improve stress resilience and boost productivity, thereby ensuring food and nutrition security in the region where it is needed the most.

“…However, the grain size of teff is very small and because of this the post-harvest loss is very high, estimated at 40.9% (22.8% at the farmer level, 2.2% at the Rural assemblers/Zone traders, 8.5% at the Wholesalers, and 7.4% at the Retailers/Millers) (FAO, 2018). The small grain size also results in difficulty in seed-handling at the time of planting, and seed contamination with soil, sand, weed, grass, and straw at the time of threshing and harvesting (Chanyalew et al, 2013;Fufa et al, 2013;Van Delden et al, 2010). Thus, increasing grain size is vital to minimize post-harvest loss and other production constraints within Ethiopia as well as increasing the attractiveness of the crop for international production.…”

Teff is an Ethiopean cereal that has the potential for increased global production. However, as a very small-seeded grain, it experiences high levels of post-harvest loss. As ethylene is reported to have a negative effect on grain size, this study sought to test whether 1-methylcyclopropene (1-MCP), an ethylene action inhibitor, is a suitable molecule to improve grain size of teff as well as to determine the optimum application time and concentration. The 1-MCP treatment was evaluated on well-watered plants as well as plants subjected to moderate water stress, with the stress treatment imposed one week before the expected flowering date. Application of 1 PPM 1-MCP to individual panicles improved grain size and thousand-grain weight (TGW) by 22% and 29% under moderate water stress and 10% and 16% under well-watered conditions, respectively. It also increased yield per panicle. However, when applied to whole plants it was not effective, due to the extended flowering time of teff and differing responses of panicles at different developmental stages. These observations suggest that genetic modification leading to lower production of endogenous ethylene could benefit grain size in teff. However, 1-MCP treatment is unlikely to be effective in the field. Keywords: grain size, TGW, 1-MCP, teff, panicle, yield-related traits
