Abstract: To study the genetic mechanism of wheat plant height, a set of doubled haploid (DH) lines were used to construct an
immortalized F (IF ) population comprising 168 different crosses. The IF population was evaluated for plant height in 2007

cropping seasons in Tai an and Liaocheng, Shandong province. Linkage map was constructed with 324 SSR markers covering the
whole wheat genome, including 284 SSR, 37 ESTs loci, 1 ISSR loci and 2 HMW-GS loci, was constructed. This linkage map
covered a total length of 2 485.7 cM with an average distance of 7.67 cM between adjacent markers. QTL analyses were
performed using the
