| Abstract: | Analysis on the yield traits and heterosis of maize variety Jidan50 were analyzed. The results showed Jidan50 had the significant effect of increasing yield. Compared with Zhengdan958 and Jingke968, it increased by 16.65% and 2.60%, respectively. Yield Heterosis of Jidan 50 had a very high level. Relative heterosis ranged from 2.29% to 66.62% with an average of 28.35%. Mid-parent heterosis ranged from 2.34% to 199.58% with an average of 55.84%. Heterosis indexes ranged from 102.34% to 299.58% with an average of 155.84%. Yield Heterosis was the highest among all yield traits. Relative heterosis, mid-parent heterosis and Heterosis indexes were 66.62%, 199.58% and 299.58%, respectively. The sequence of the other traits from high to low was yield per plant, ear height, kernel number per row, ear length, plant height, cob diameter, ear diameter, row number per ear, 100-kernel weight, kernel ratio and grain moisture content. |
