Status of Ethiopian durum wheat varieties for the stem rust disease resistance under field condition

Production of wheat in Ethiopia is under danger from stem rust, which brought on by the disease Puccinia graminis f.sp. tritici and has resulted a yield loss 100%. An investigation was conducted hotspot area (Debere Zeit, Ethiopia) to evaluate status Ethiopian durum cultivars for their level rust resistance field. During main seasons 2017, 2020, 2021, 34 varieties with three susceptibility checks were examined. Terminal Rust Severity (TRS), Coefficient Infection (CI) Area Disease Progress Curve (AUDPC) used measure field resistance. Analysis all parameters carried out using R studio. Due low levels AUDPC, ACI, TRS values combined MR infection type, two commercial (Oda Tob-66) may have significant gene(s) seven (Boohie, Kilinto, Ginchi, Robe, Toltu, Lelisso, Bekelcha) showed moderate MRMS responses adult plant mediated minor genes. Stem found affect 73.5% cultivars. Therefore, this study suggests that national breeding effort should focus local rather than ones imported. Key words: Field resistance, wheat, f.sp tritici.
