“…Several studies reported genes ( Bt4 , Bt5 , and Bt6 ) and QTLs associated with Cbt resistance on chromosome 1B (Dumalasová et al., 2012; Ehn et al., 2022; Fofana et al., 2008; Iqbal et al., 2022; Mourad et al., 2018; Muellner et al., 2021; Scmidt et al., 1969; Singh et al., 2016; Wang et al., 2009), 2B (Chen et al., 2016; Ehn et al., 2022; Iqbal et al., 2022; Steffan et al., 2022), and 6D (Gordon et al., 2020; Iqbal et al., 2022; Singh et al., 2016). The positions of the Cbt resistance genes and QTLs on 1B varied across populations and includes 11.2 Mb near BS00032266_51 in a diversity panel of bread wheat accessions from the USDA National Small Grains Collection (Ehn et al., 2022), 4.4–38.9 Mb in two RIL populations derived from Blizzard/Rainer and Bonneville/Rainer (Muellner et al., 2021), and 645.2 Mb in Canadian spring wheat (Iqbal et al., 2022). The physical position of the QCbt.dms‐1B identified in the present study, therefore, overlapped with the QTLs reported in the USDA bread wheat accessions and the two RIL (Blizzard/Rainer and Bonneville/ Rainer) populations.…”
