Low (Roelfs and McVey, 1979).
Common wheat cv. Kota. Kota was included in the differential set of Stakman et al. (1962).
Virulence is common in all geographic areas (Luig, 1983). Huerta-Espino (1992) found significant levels of avirulence among cultures from Ethiopia and Nepal; otherwise virulence levels were high.
i: Line AD = W2691*5/Kota (McIntosh, 1978).
s: Ceres Sr7b (McIntosh, 1978); Kota Sr7b (McIntosh, 1978).
Use in Agriculture
Sr28 is of limited use in current wheat breeding. However, it was the basis for resistance in cultivar Ceres released in the USA and rendered susceptible by race 56 in 1935.
