Bread wheat production is reduced by wheat fungal wheat rust diseases: Stem rust, Yellow rust, and Leaf rust. In Ethiopia, stem rust and yellow rust are the two major wheat rusts in occurrence and importance. Through evaluation and selection for years, noble bread wheat varieties can be developed and released. The National Wheat Research Program Introduced the 21 Spring Bread Wheat Trial from International Center for Agricultural Research in the Dry Areas (ICARDA) in 2021. The trial had a total of fifty entries: forty seven genotype, two checks, and one empty room for the local check. The design was alpha lattice design with two replications. A rep had five sub-blocks; the sub-block had ten plots. The plot size was 2.5m in length by 1.2m in width. The total area of the plot was 3m2 and planted with six rows. Genotypic and phenotypic correlations between wheat rust diseases and other trait computed to see the relationship. The top six highly susceptible genotypes for yellow rust were: EBW214106, EBW214090, EBW214089, EBW214074, EBW214099, and EBW214097. Some genotypes were susceptible to both diseases; others were resistant to one of the diseases. ETBW EBW214113 had the highest CI for stem rust and the lowest CI for yellow rust. At Kulumsa, negative genotypic correlations were obtained between yellow rust and DTH r = -0.17; between yellow rust and DTM r = -0.23; between yellow rust and PHT r = -0.67***; SRCI, r = -0.33*; TKW, r = -0.79***; HLW, r = -0.57***; and GYLD, r= -0.85. Ethiopia is one of the hotspot areas for these diseases. Thus, selections for resistance genotypes are a precondition in releasing wheat variety for the farmers.
