中文摘要:
      针对玉米育种和生产上缺乏抗病优质自交系的难题,以国内自交系掖478与含有热带血缘外引杂交种后代选系P249杂交、回交及多代自交,培育出具有温-热带种质的多抗优质自交系早48。该自交系具有株型紧凑,抗病性强,配合力高,品质优良,生育期适中等优良特性。利用早48自交系组配育成的强盛31、晋单44、忻玉110、咏丰1号、晋阳2号、晋单70等6个杂交种通过国家或省级审定。这些新品种已在我国东华北早熟区、黄淮海夏播区大面积推广应用,取得较大的社会经济效益。
英文摘要:
      For the narrow genetic basis of maize germplasm and the lacking of excellent resistant maize inbred lines in breeding and production, the domestic inbred line‘Ye478’and exotic hybrid progeny‘P249’with tropical germplasm were used to cross, backcross and multi-generation selfing, and breed the multi-resistant and high- quality inbred line‘Zao48’with the temperate- tropical background.‘Zao48’had high multidisease resistance to stem rot, dwarf mosaic disease, corn southern leaf blight, corn northern leaf blight and ear rot. It had high content of crude protein and crude starch in grain. It also had compact plant type, dwarf stalk with lodging- resistant, strong combining ability and wide adaptability. Six hybrid cultivars including ‘Qiangsheng31’,‘Jindan44’,‘Xinyu110’,‘Yongfeng No.1’,‘Jinyang No.2’and‘Jindan70’from‘Zao48’ inbred line combination were approved by the National or Provincial Crops Variety Approval Committee. These new cultivars have been promoted and applied widely in northeastern and northern early- maturity maize regions, Huanghuaihai summer maize region, and achieved huge social and economic benefits.
