Tef [Eragrostis tef (Zucc.) Trotter] is the staple cereal of Ethiopia occupying close to two million hectares. All the breeding efforts to date relied upon selection from the existing natural With 2 figures and 5 tables Tef [Eragrostis tef (Zucc.) Trotter] is an important food staple cereal crop in Ethiopia. Despite its importance in the Ethiopian agriculture, there are constraints of tef were lower in total protein content than that of other wild Eragrostis species. Thus, he suggested the possibility for improving the protein content of tef through an interspecific breeding   Highlights We examined genetic diversity and relationships among cultivated tef and 13 wild accessions. 39 SSR markers differentiated % of the accessions and revealed a high level of genetic diversity. It was discovered that seed admixture is a serious problem affecting the integrity of tef varieties. Results indicate that tef plant breeders have been using a broad range of germplasm

Tef is cultivated by more than five million small-scale farmers annually and constitutes the staple food for more than half of the population of 80 Introduction. Tef [Eragrostis tef (Zucc.)Trotter] is the most important cereal in Ethiopia. It constitutes the staple food for more than half of the Ethiopian population and is grown on roughly 3 of the 8 million ha used to cultivate cereals annually (CSA, –).Approximately million tons of the crop is produced per year in Ethiopia, and most of this is consumed within the :// There are considerable variations in the productivity of plots growing teff across Ethiopia. The major drivers for productivity differences appear to be the levels of input use, the management practices employed, the age of the operator, the ease of access to markets, and the level of engagement in extension efforts. The findings lead to a number of policy ://   In hydroponic culture solutions Tef (Eragrostis tef), unlike some other species of Eragrostis and related eragrostoid grasses such as Leptochloa fusca, was found to be salt sensitive and unable to withstand a major reduction in its leaf relative water salt sensitivity was found to be related to an inability to restrict the influx of sodium and chloride into the ://

Tef [Eragrostis tef (Zucc.) Trotter] is an allotetraploid (2n=4x=40) cereal with its centers of domestication and diversity in Ethiopia. It is the only cultivated species in the genus Eragrostis that contains about species. In Ethiopia, about two million hectares of land is devoted to its production every year. Despite its importance in the Ethiopian agriculture for centuries, there are Tef, Eragrostis tef (Zucc.) Trotter, is the most important cereal in Ethiopia. Tef is cultivated by more than five million small-scale farmers annually and constitutes the staple food for more Teff is domesticated in Ethiopia and is locally important. Seventy accessions of teff collected from seven regions have been sown in a balanced block design. Significant and highly significant variation was observed between regions, within region and between individual plants within accession for most of the characters considered. Regions showed variations for different characteristics   Transformation of E. tef using IE and PcGA2ox as transgene gave chimeric putative transformants at To.. KBP and K4NB were successfully used as CIM and maturation media for Agro transformation in E. tef.. Detection of insert was inconsistent in T 1 plants and further study is needed to rule out somaclonal variation as a cause.. Up to 56% reduction in culm height was obtained compared
