One of the most harmful wheat diseases in Ethiopia is stem rust caused by Puccinia graminis f. sp. tritici (Pgt). It has the capacity to result in yield losses of up to 100% on susceptible cultivars. In a study, forty-two wheat lines along with one susceptible check were tested for their ability to fight off eleven isolates of the stem rust races TTKSK (Ug99 race), TTRTF, TKTTF (Digalu race), JRCQC, TKKTF, TRTTF, TTTTF, TTKTF, TTKTT, RRTTF, and TKPTF. In the Ambo Plant Protection Research Center in 2021, wheat lines were experimentally infected with urediniospores of the various races under controlled circumstances. Different seedling resistance responses were seen against the Pgt races that were investigated. Thirteen wheat lines (WL-1, WL-4, WL-21, WL-35, WL-37, WL-38, WL-41, WL-43, WL-45, WL-48, WL-49, WL-61, WL-64), which demonstrated low infection types (ITs of 2 or lower) against all the races, resulted in twenty-three lines having both resistant and susceptible infection types (ITs 0 to 3), In contrast, susceptible checks and six wheat lines (WL-26, WL-31, WL-33, WL-47, WL-51, WL-66) consistently showed susceptible infection types (ITs 2+ to 3+) to all races. The study's found resistant wheat lines can be employed as sources of resistance in the breeding program for wheat.
