Abstract
Yield trials of 7 different rice varieties(Including five upland varieties and two paddy varieties) were carried out under normal irrigated and drought stress conditions separately.Grain yield and yield components and quality traits of two trials were analyzed and compared.The results showed that serious yield loss was caused by lasting drought stress during mid-late stage.The reduction of spikelets per panicle was the primary cause to the yield loss under the drought stress condition.The upland rice was more adapted to drought stress compared with paddy rice.The seed setting rate was much higher than that of the paddy rice under the drought stress.Moderate drought stress during the grain filling stage might have the effects of increasing the head rice rate and decreasing chalkiness.
