摘要
在回顾我国玉米育种种质来源(国内地方品种、国外自交系和国外杂交种及群体)的基础上,提出我国主要温带自交系可划分为6个群,即塘四平头群、兰卡斯特群、类兰卡斯特群、PA群、PB群和PC群,玉米的骨干亲本包括丹340、黄早四、自330、Mo17和掖478等。对我国玉米种质资源和骨干亲本研究提出了研究方向和重点工作。
Based on retrospective review on germplasm sources of maize breeding in China,i.e.local landraces,overseas inbred lines,overseas hybrids and populations,it was suggested that a major of temperate inbred in China could be divided into six groups,that was,Tangsipingtou,Lancaster,Lancaster-like,PA,PB and PC.The foundation parents used in maize breeding included Dan 340,Huangzaosi,Zi330,Mo17 and Ye478 etc.In this paper,directions and priorities of research on germplasm resources and foundation parents were also...
