Abstract

Powdery mildew is one of the most serious diseases of wheat in China. In this paper,bulked segregant analysis (BSA) was used to search for randomly amplified polymorphic DNA (RAPD) markers linked to the Pm12 gene,which confers resistance to the powdery mildew in wheat. 200 decamer primers were screened and one RAPD marker (S1071900) was identified to be linked to Pm 12 in coupling phase, and their genetic distance is 11.98 ±4.00cM. This marker can be used for marker - assisted selection in wheat breeding for the identification or pyramiding of Pm12 with other resistance genes.Key Words: Wheat, RAPD, Powdery mildew, resistance genes.
