摘　　要：针对不同生态区水热资源紧缺,风灾倒伏频发、产量低、品质差等问题,以‘京X005’为母本、‘京27’为父本进行杂交培育成玉米新品种‘MC278’。该品种在吉林、河北等地接种表明,对小斑病、弯孢病、矮花叶病、丝黑穗病、茎腐病的抗性较强,易感染大斑病,中抗吉林地区玉米螟。在北京、内蒙等地不同年度的区试中,‘MC278’籽粒产量显著高于‘郑单958’(CK),产量最高达16166 kg/hm^(2),平均产量增幅达8.3%;‘MC278’的粗蛋白质、粗淀粉、赖氨酸含量显著高于‘郑单958’。2019年河北、山西、内蒙等地生产中,产量均高于12804 kg/hm^(2),产量最高达14283 kg/hm^(2);‘MC278’配套适宜播期、密度、水肥和病虫害防治等田间管理措施及收获技术。2019年通过国家审定(国审玉20190030),种植区域包括安徽、山西、山东等15个省级区域。In view of the shortage of water and heat resources in different ecological areas, and the frequent occurrence of wind disaster, lodging, low yield, poor quality and other problems in maize production, a new maize variety‘MC278’was bred by taking‘Jing X005’as female parent and‘Jing 27’as male parent. The inoculation tests of the variety in Jilin, Hebei and other places showed that it had strong resistance to small spot disease, Curvularia, dwarf mosaic, silk smut and stem rot, and was easy to infect large leaf spot, and it was moderately resistant to corn borer in Jilin. In the regional trials in Beijing, Inner Mongolia and other regions in different years, the kernel yield of‘MC278’was significantly higher than that of‘Zhengdan 958’(CK), the highest yield was 16166 kg/hm^(2), and the average yield was increased by 8.3%. The content of crude protein,crude starch and lysine of‘MC278’were significantly higher than those of‘Zhengdan 958’. In 2019, the production in Hebei, Shanxi, Inner Mongolia and other regions showed that the yield of‘MC278’was all more than 12804 kg/hm^(2), and the maximum yield was 14283 kg/hm^(2).‘MC278’was equipped with field management measures and harvest techniques, such as suitable sowing date, density and water and fertilizer management,and prevention and control measures of diseases and insect pests. The variety passed the national examination and approval in 2019(National Approved Maize Variety No.20190030), and its planting area now includes 15provincial regions, such as Anhui, Shanxi, Shandong and etc.
