Abstract
In this study,the experiment was carried out in two water treatments,drought and irrigation.Eight winter wheat varieties used in dry land at different ages and one winter wheat variety used in irrigated land were chosen to study their grain filling characteristics during the filling stage and their yield differences.The results showed that under the two water treatments,the grain yield and thousand kernel weight increased as the replacing progress,and the filling speed and days for grainfilling also increased.In addition,under the drought condition,the average grain filling duration was reduced,and which was lesser in the later varieties than in early varieties;the average grain filling rate declined slightly for earlier varieties while increased in dry land wheat Changhan 58and Changwu134.The grain weight of irrigated land variety Xinong 9871under irrigation condition was much higher than that under drought treatment,but there was no significant difference for dry-land varieties between the two water treatments.The study suggested that the increase of both filling rate and days were the main factors to improve the grain weight and yield of modern dry land varieties.
