Abstract: Wheat powdery mildew is one of the main diseases threaten wheat production in China even all over the world. Screening and development disease-resistant varieties is a safe and effective way for prevention and control of wheat powdery mildew. The purpose of this study is to introduce powdery mildew resistance gene Pm30 into the wheat varieties Jizi 356 with advanced comprehensive agronomic characters and high yield developed by authors. One crosses,Jizi 356/Synthetics He-48 were made. Twelve lines with field resistance to powdery mildew and excellent agronomic characters were developed after six years of offspring screening. Then,seven lines were used for identifying resistance gene Pm30 using Xgwm159 SSR marker. Chinese spring and Pm30 were used as a contrast. The results showed that two new lines 14YF650 and 14YF675 could amplify the 430,460,500 bp polymorphic fragments. It indicated the two lines carrying Pm30 powdery mildew resistance gene derived from wild emmer. Those lines with big spikes,resistant to lodging and excellent agronomic characters could be used directly as parents for wheat powdery mildew resistance breeding.
