Abstract: A double haploid (DH) population including 96 lines derived from the cross ‘AzucenaxIR64' was used to investigate four physiological traits of rice leaves at the tillering stage under water stress mimicked by 10% PEG- 6000 solution for 7 days. Based on the genetic linkage map with 285 markers,QTLs associated with chlorophyll content, stomatal resistance, temperature and water content of rice leaves were identified. Six QTLs with additive effects and six pairs of QTLs with epistatic effects for the four physiological traits related to drought resistance were detected under water stress.
