摘要： Photosynthesis is an essential physiological process in plants' growth and dry matter production. There is great genetic diversity in photosynthesis among rice germplasm (Cao et al., 2001). Usually, the plant with high photosynthesis can produce morebiomass and grain yield. Recent studies on paddy rice under irrigated conditions indicates that the photosynthetic rate (PR), chlorophyll content (CC), stomatal resistance (SR), and transpiration rate are quantitative traits and affected by several QTLs(Teng et al., 2004). In this paper, a RIL population from a paddy rice and upland rice cultivar were investigated for PR, CC, SR, TR, as well as water use efficiency (WUE) in both irrigated (normal) and drought (stress) conditions. The molecular dissection was also conducted to map the related QTLs. The results will help us understand the genetic bases of photosynthesis under drought occurrence in rice production.
