| Abstract: |
| Fresh ear yield, fresh grain yield, panicle traits, plant characteristics and maturation periods of the waxy corn Shennuo 9 were studied under five densities using local main cultivar Kennian1 and Jingkenuo 2000 as control. The results show that effects of density on the three varieties were significant; fresh ear yield, spike length, ear diameter and ear rows of Shennuo 9 were obviously higher than that of Kenian1 and Jingkenuo 2000; grain depth, grains per row, 100-grain weight and plant height of Shennuo 9 is comparable to Jingkenuo 2000 whereas significantly higher than Kennian1. The ear position of Shennuo 9 is lower than that of Jingkenuo 2000. Maturation period of Shennuo 9 was six later days and nine days earlier than that of Kennian1 and Jingkenuo 2000, even fill in gaps in maturation period of Kennianl and Jingkenuo 2000. In conclusion, yield, panicle traits and field performance of Shennuo 9 are better than that of Kennian1 and Jingkenuo 2000, indicating that Shennuo 9 is suitable for Southeast of Heilongjiang Province. |
