Abstract:

Though many kinds of hybrid corn varieties continuously come out, the suitable planted regions are different. With the purpose of providing theory basis for selecting varieties which are suitable for the soil of Hongta District, in this study, it introduced a comparative trial to 7 new varieties of corn, and made a research for each variety’s feature, resistance and corn yield. The results showed: comparing with ‘Haihe2’and‘Xidan5’, ‘DY205’ can produce more, appeared moderate growing period, compact-type, orderly adult plant, and had a higher resistance to rust and gray speck disease. The maximum output per hectare of ‘Xidan5’ could reach 11400.00 kg, the growth period was 134 days, the height was 270.6 cm, the ear height was 123.9 cm, the length of corn ear was 20.3 cm, there were 15.8 ear rows and 36.2 kernels in each row, the thousand weight was 378.9 g, it could be grown in wider range of areas, and get the grain in timely. The output per hectare of ‘DY205’ could reach 11125.00 kg, the growth period was 136 days, the height of the plant was 289.7 cm, the ear height was 137.3 cm, the length of corn ear was 21.3 cm, in one ear of this corn, there were 14.8 ear rows and each row had 32.6 kernels, one thousand weight was 400.8 g, it could be grown in wider range of areas.
