Abstract
In order to improve the efficiency for high yield and ideotype in wheat breeding,128 RILs from the cross of common wheat(Triticum aestivum L.)Ningchun 4× Ningchun 27 were used as the plant materials.307 polymorphic SSR markers were screened out of 1001 SSR markers and used for QTL mapping.A genetic linkage map covering wheat chromosomes was constructed,which contains291 SSR markers,with a total genetic distance of 2 576.09 cM.The ICIM mapping method was used for detecting QTLs of three different traits in three experimental locations.6 QTLs of flag leaf length,8QTLs of flag leaf width,4QTLs of chlorophyll relative content were detected,but most of the QTLs were specific to single environment,indicating that environment effect also played a role in controlling wheat flag leaf traits.
