摘　　要：基于2010-2019年河南省年种植面积0.67×10^(4)hm^(2)以上玉米品种的种植面积及育种单位信息,分析河南省玉米品种利用及育种单位推广情况,为河南省玉米生产选种及种业发展提供参考。结果表明,2010-2019年河南省年种植面积0.67×10^(4)hm^(2)以上的品种200个,累计种植年数4年以上的品种73个,累计种植面积33.33×10^(4)hm^(2)以上的品种19个,其中,16个已过种植高峰期,生产上面临品种更新换代压力。种子企业和科研院所是品种选育的主要力量,随着年份更替,种子企业选育品种数量及种植面积占比不断攀升,远超科研院所。外省选育品种种植面积占比呈上升趋势,外资进入对河南省玉米种业造成一定冲击,河南省迫切需要进一步加强培育本省种业品牌。近几年,河南省先后建设了国家生物育种产业创新中心及神农种业实验室,积极推进现代种业强省建设,努力为我国打好种业翻身仗做出贡献。Based on the planting area and breeding organization information of maize varieties with an annual planting area of more than 0.67×10^(4)ha in Henan Province from 2010 to 2019,the variety utilization and breeding or⁃ganization in Henan Province were analyzed to provide reference for the selection of seeds and the development of seed industry in Henan Province.The results showed that the number of maize varieties with an annual planting ar⁃ea of more than 0.67×10^(4)ha was 200 in Henan Province from 2010 to 2019,the number of maize varieties with an accumulated planting year of more than 4 years was 73,the number of maize varieties with an accumulated planting area of more than 33.33×10^(4)ha was 19,16 of which had passed the planting peak period,and the pressure of upgrad⁃ing of variety was high.Seed enterprises and scientific research institutes were the main force of variety breeding.The proportion of varieties count and planting area bred by seed enterprises increased continuously,far exceeding that of scientific research institutes.The proportion of planting area of varieties bred by breeding organization in oth⁃er provinces showed an increasing trend.The entry of foreign capital had a certain impact on the maize seed indus⁃try in Henan Province.It was very urgent to further strengthen the cultivation of its own seed industry brand for Henan Province.In recent years,Henan Province has successively built State Industrial Innovation Center of Biolog⁃ical Breeding and The Shennong Laboratory,actively promoted the construction of a strong modern seed industry province,and made contributions to the turnaround of China's seed industry.
