With all of the special treatment had no significant variation, and maintained the special inbred line with the original force. 各處理的特殊配合力無顯著變異,保持了原自交系的特殊配合力。
In order to improve its yield, the proper method for higher density breeding should be applied to screen the better inbred lines of maize. 為了進一步挖掘玉米自交系的產量潛力,應廣泛採用高密度選系手段,通過創造適當的逆境以篩選無禿尖的自交系。
