摘要
为筛选适宜大新县昌明乡种植的高产、优质、抗病、熟期适中的杂交玉米品种,2009年引进10个杂交玉米新品种进行田间比较试验。结果表明,太平洋98、正大629、红单4号、桂单30、红单3号较对照正大619增产,增产幅度为1.32%～18.95%,生育期118～123 d,均可在生产上推广种植,但从抗性及品质上看,太平洋98、红单3号抗性好、粒色好,更受农民欢迎;正大305、正大518、正大16、苏玉10号、三元灯391因丰产性、抗逆性差,不宜在当地推广种植。
In order to screen new corn varieties with good quality,high yield,strong resistance to diseases and suitable harvesting time,and to find out their suitability for planting in Changming town of Daxin county,10 new corn varieties were tested in a field experiment in 2009.The yield of varieties Taipingyang 98,Zhengda 629,Hongdan 4,Guidan 30 and Hongdan 3（1.32-18.95% higher as compared to control variety Zhengda 619） and 118-123 days growth duration indicated their suitability for planting in Changming town.Further,famers prefer Taipingyang 98 and Hongdan 3 rather than other corn varieties due to strong resistance to diseases and fine ear appearance,while Zhengda 305,Zhengda 518,Zhengda 16,Suyu 10 and Sanyuandeng 391 were unsuitable for extension in Changming town Daxin county because of their low yield and weak resistance.
