[Objective] The aim was to supply theoretical basis for high- and stable-yield,high-quality and high-efficiency cultivation of wheat in Xuhuai district.[Method] The effects of physiological properties in later growth stage on the high-yield performance of wheat were analyzed by determining the filling speeds,root bleaching amounts per stem,root weights,leaf area coefficients and functional days of the 2 top leaves of Xumai856,Huaimai20 and Yanfu188.[Result] The average filling speed of Xumai856 was highest.Compared with Huaimai20 and Yanfu188,the filling stage of Xumai856 was extended for 4 and 2 d and the inter-annual variation coefficient of its 1 000-seed weight was less; its root weight per unit area in underground 0-20 cm soil was enhanced by 46.7% and 24.2% resp.and that in underground 20～40 cm soil was enhanced by 65.5% and 13.3% resp.; its average root bleaching amount per stem in middle and late filling stage was enhanced by 31.9% and 20.1% resp.; its average functional days of flag and second leaf were extended for 5 and 3 d resp.[Conclusion] The high-yield performance of Xumai856 was dependent on its physiological properties of fast filling speed and long filling stage.
