Abstract
SSR analysis was performed using a wheat near-isogenic line (NIL) Taichuang29 * 6/ Lovrin13, which carried the resistance gene Yr9 against wheat stripe rust and its recurrent parent Taichung29 as materials. After screening with 32 SSR primers on 1B chromosome, reproducible polymorphic DNA fragment amplified by Xgwm582 was identified. Genetic linkage was tested in 177 segregating F2 plants. The results indicated that microsatellite marker Xgwm582 was linked with gene Yr9 resistant to wheat stripe rust. A genetic distance of 3. 7 cM was calculated.
