Abstract: In order to screen the silage maize varieties suitable for planting and popularization in Daqing area of Heilongjiang Province,a total of 15 silage maize varieties were introduced and compared in yield and agronomic traits.The differences in fresh weight,dry weight,plant height,stem diameter,leaf number,green leaf number and ear height between the introduced silage maize varieties were characterized,and the correlation between yield and agronomic traits was analyzed.The results showed that the varieties of Zhongyuandan No.32 and Beiyu silage No.1 had the best comprehensive performance,and both of their yield exceeded 63 000 kg/hm^2.In addition,there was a extremely significantly positive correlation between ear height and yield.This study provides a reference for the cultivation and promotion of silage maize in Daqing area.
