Abstract
Pericarp color in wheat is an important trait related to nutrients and health benefits Identification of molecular markers closely linked to the grain color genes will help utilize pericarp trait in wheat breeding Genetic studies involving F1 F2 and F3 populations from the cross Jizi 439 purple grain/Gao8901 white grain showed that the purple grain color was controlled by two genes By using the bulked segregant analysis BSA approach two DNA pools were established from the dark purplegrain and whitegrain plants respectively Among the 230 pairs of microsatellite primers used in this study two markers showed polymorphism in DNA pools parents F1 and F2 populations Linkage analysis indicated that the two markers Xgwm47 and Xgwm155 were linked with two purple pigment genes One of the purple pigment genes is located on chromosome 2AS and is 347cM away from the marker Xgwm47 whereas another gene is mapped on 3AL with 147cM away from marker Xgwm155We thank Dr Gongshe Hu DrB B Singh and Jingxian Zhang for their valuable comments on the manuscript This work was supported by the both Provencal Natural Science Foundation of Hebei 302468 and National science and technology underpinning Project of China 2006BAD13B0208
