A linkage map consisted of 144 SSR (simple sequence repeat) markers was constructed based on a recombinant inbred line (RIL) population of rice from the cross between Chuanxiang 29B and Zhongguoxiangdao.Quantitative trait loci (QTLs) related with rice qualities of appearance,cooking and eating were analyzed.A total of 45 QTLs for grain length,grain width,length-width rate,chalkiness rate,amylase content and alkali spread value were identified and mapped onto the rice chromosome 1,2,3,4,6,7,9,10 and 12.Nine QTLs can be repetively detected in two years.These QTLs were useful for improving the quality of Chuanxiang 29B through molecular marker-assisted selection.
