Black point disease (BP) severely affects wheat production, and planting disease-resistant varieties is an important measure to mitigate the damage caused by BP. However, the current lack of resistance sources restricts the improvement of BP resistance. To obtain superior resistance sources for BP, this study inoculated 412 wheat germplasm with the dominant pathogen of BP in the Huanghuai wheat region, Bipolaris sorokiniana, and conducted molecular testing using 16 reported BP resistance-related markers. The results showed that among the 412 tested materials, there were no immune or highly resistant germplasm; 4 showed moderate resistance (1.0%), while 95 (23.1%), 209 (50.7%), and 104 (25.2%) exhibited mild susceptibility, moderate susceptibility, and high susceptibility, respectively. Of the 16 markers, 13 showed polymorphism among different materials, with only 3 tightly linked to BP resistance: wmc170, BP-4A-d20, and Xbarc10. These correspond to the resistance loci QBP-Usq.2A, QBB.hau-4A, and QBB.hau-5A, respectively, with QBB.hau-4A exhibiting a better disease resistance effect. Its presence alone or in combination with other loci can significantly reduce the black point rate in wheat (P<0.01). The 4 moderately resistant materials (Shannong 530070, ZC223, 05CV078, and Shannong 38) can serve as resistance sources for improving BP resistance in wheat, and BP-4A-d20 marker can be used for BP resistance breeding.
