东北农业大学以引进的欧洲玉米种质为材料,利用系谱法获得了一批自交系,本试验选择其中的41份中晚熟玉米自交系为试验材料,对其进行农艺性状、产量性状、耐密性、抗病性等鉴定,为这些欧洲玉米选系的有效利用提供理论依据。结果表明, P16-9-1、F25-16-1、P03-6-1等18份自交系在农艺性状和产量性状上表现优良；P03-6-1、F26-5-1、PA4-5-3-2等16份选系具有较好的耐密植能力；F26-8-3、R11-10-1、F25-15-2等20份选系兼抗大斑和丝黑穗病； P20-1-1、F25-16-1、F26-8-3、P16-6、P16-9-1、R11-11-1、F26-6-1和F25-16-3等8份选系综合表现优良,具有株高和穗位适中、耐密好、雄穗性状较好、抗或高抗丝黑穗病和大斑病等特点。
英文摘要:
Forty oneSmid-late maize inbred lines from European germplasm bred by Maize Institute of Northeast Agricultural University were used to analyze the comprehensive utilization value based on the agronomic traits, yield related traits, density-tolerance, lodging resistance and disease resistance. The results showed that the comprehensive agronomic traits of 18 selected lines were well, including P16-9-1, F25-16-1, P03-6-1, etc. Sixteen lines were resistant to density, such as P03-6-1, F26-5-1, PA4-5-3-2, etc. Twenty lines showed resistance of both head smut and leaf blight, such as F26-8-3、R11-10-1、F25-15-2. Eight lines from European maize germplasm were highlight with proper height, longer total tassel length, 14-16 kernel rows, high 100-grain weight, inScomprehensive characteristics, including P20-1-1, F25-16-1, F26-8-3, P16-6, P16-9-1, R11-11-1, F26-6-1 and F25-16-3.
