| 摘 要： | 利用籼稻品种IR64和粳稻品种Azucena杂交产生的包含96个加倍单倍体株系的群体．在分蘖期用10％PEG一6000模拟水分胁迫处理7d，测定了叶片叶绿素含量、气孔阻力、叶温和含水量，利用285个分子标记构建的遗传连锁图谱，共检测到与抗旱性相关的4个生理指标的6个加性QTL和6对上位性QTL。

| Abstract: | A double haploid (DH) population including 96 lines derived from the cross 'Azucena×IR64' 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. |
