Abstract

Abstract: Screening powdery mildew resistance genes from wheat Genetic resources was conducted,so that re- sistance genes can be provided for powdery mildew resisitant breeding and theoretical basis and technical support was laided for identification resistance genes in breeding offspring. 65 accessions of wheat genetic resources from Hebei were used for identifying resistance genes using STS markers. The results showed that variety Jinhe 7178, He- nong 7069 and Qiumai,carrying Pm21,Pm4a and csLV34 powdery mildew resistance genes respectively. Those vari- eties as parents.can be used for wheat powdery mildew resistance breeding.

Key words: Wheat（ Triticum aestivum L. ）, Powdery mildew resistant gene, STS Molecular markers
