| Abstract: | The new corn hybrid,98-ZW-1 was bred by Baiyin Agri-Sci Institute using 98-W-1 as female parent and 98-Z-1 as male parent.The average yield was of 98-ZW-1 12 032.25 kg,more than Shendan No.10 by 9.78% in regional trial during the period 2002-2003.The average yield was 12 063.54 kg,more than Shendan No.10 by 3.3% in production test During the period 2002-2004.It was an mid-early ripe corn hybrid with height of 246 cm,100 kernel weight of 40.0 g.The result also indicated that seed crude pertein,crude fat,starch and lysine were respectively 111.0 g/kg,46.2 g/kg,716.2 g/kg and 3.6 g/kg.It was resistant to spot disease and red-leaf disease,suitable to high-lift irrigation district in high altitude,arid and semi-arid areas in Baiyin city. |
