Yield effect of different wheat genotypes under varied water treatments

The effects of water alteration on the yield of different wheat genotypes and stage were studied. The results show that water variation at the jointing stage has a great effect on the yield. Under the effect of dropping yield owing to drought, compared with that of the well-watered treatment, the common wheat yield shrinks 29.45% at jointing stage, but only 12.70% at grainfilling stage. Compared with that of the water stress treatment, the common wheat yield increases 42.83% after rewatering at jointing stage, while increases 22.29% at grainfilling stage. Among different wheat genotypes, the yields of Zaipeiyili and Zaipeierli have only a change of 8.76% and 4.38% after rewatering at jointing stage.
