Abstract：Using the maize variety Changcheng 706 as a control,a field trial was conducted in a mountainous area of southern Ningxia to investigate three representative maize varieties that had been authorized (Huajin 5,Funong 821,and Ningdan 20)for their charac-teristics of grain filling and dry matter accumulation.The tested varieties were compared in terms of agronomic traits,panicle traits, yield,the mass of dry matter accumulated in plant,and filling rate.Results showed that Funong 821 and Ningdan 20 both matured on September 20,indicating that they had the same mature period,which was earlier than that of the control variety by six days.Among all tested varieties,Ningdan 20 had the highest value of 100-grain weight.On the other hand,Huajin 5 achieved a very significantly higher yield than the other three varieties(P<0.01);meanwhile,the differences in yield among the other three varieties also reached a very significant level(P<0.01).
