摘　　要：为促进优良玉米自交系选育,黑龙江省农业科学院齐齐哈尔分院玉米遗传育种研究室以美国先锋公司玉米杂交种作为种质基础,运用不同选育手段进行改良选系,成功筛选出一批具有抗病抗逆、品质优良、脱水快等优点的种质资源。本文选取其中15份种质有针对性地进行血缘划分,明确种质隶属群。黑龙江省农业科学院齐齐哈尔分院玉米遗传育种课题组利用杂种优势选育出具有代表性的玉米杂交种二环系1064、NL881和0999,进一步成功选育出玉米新品种嫩单23、嫩单27、嫩单29和嫩单35,在黑龙江省中晚熟组起到了关键性作用,缩短了与国外品种的差距。In order to promote the selection and breeding of excellent maize inbred lines,the Maize Genetics and Breeding Laboratory of Qiqihar Branch of Heilongjiang Academy of Agricultural Sciences used American Pioneer Company′s maize hybrids as the germplasm basis and used different breeding methods to improve the selection of lines,and successfully selected a batch of resistant lines.Germplasm resources with the advantages of disease resistance,high quality,and fast dehydration.In this paper,15 germplasms were selected for blood relationship classification,and the germplasm belonged to the group.This research group used different heterosis to select representative corn hybrids,two ring lines 1064,NL881 and 0999,and further successfully bred new maize varieties Nendan 23,Nendan 27,Nendan 29 and Nendan 35.It played a key role in the middle and late maturity group in Heilongjiang Province,shortening the gap with foreign varieties.
