Summary of phenotypic data of 221 tetraploid wheat accessions evaluated for their reaction to Blumeria graminis f. sp. tritici at adult plant and seedling stages. All lines were classified into two groups with resistant lines (R) scoring 0–2 at seedlings and adult plants, and susceptible lines (S) scoring 2.1–4.0 for seedlings and 2.1–9.0 for adult plants. SD = standard deviation. RR = Resistant accessions at seedling and adult plant stages.
