新型玉米杂交种九和玉1号的选育与栽培技术研究

Research on Breeding and Cultural Technology for New Maize Hybrids of Jiuheyu1

九和玉1号于2017年通过陕西省夏玉米区机收组审定,在2018年分别通过河南、山东、河北、江苏、安徽等省的引种认定,在2019年被推荐进入黄淮海夏玉米区国家机收组生产试验,表现优异,有望通过国家的审定。九和玉1号是以PPC12为母本,以ZDK26为父本,于2010年组配选育而成的玉米单交种。具有高产、稳产、适应广、抗逆性强、绿色抗虫、抗病、抗倒、耐高温、耐干旱、耐密、早熟、脱水快、易机收的优良性状。为了九和玉1号更好的服务于现代化玉米产业生产,对该品种的选育过程、亲本特性、品种特性、制种技术、栽培技术等方面进行了详细的分析和研究,为玉米产业生产提供技术依据和参考。

Jiuheyu1 was examined and approved of in the summer maize mechanical harvest block by Shaanxi Province in 2017;Introduction test was succeeded in 2018 at He’nan,Shandong,Jiangshu,Anhui and so on.Jiuheyu1 was selected to get into Huang-Huai-Hai summer maize area production test of mechanical harvest block,and showed excellence,and it was hoped to be authorized by National Crop Variety Examination and Approving Committee.The maize hybrids of Jiuheyu1 was obtained by using“PPC12”as female parent and“ZDK26”as male parent in 2010,and it was characterized by advantages such as high and stable yield,good adaptability,strong resistance,insect resistance,disease resistance,lodging resistance,high heat resistance,dry resistance,density toleration,early maturity,dehydrating speed,and easily mechanical harvest.To make Jiuheyu1 serve modern industrial maize production,this paper analyzed and studied its breeding process,characteristics of parents,variety characters,seed production,cultivation technology,and so on.The results provided a useful theoretical basis and technological references for modern industrial maize production.
