| 摘 要： | 搜集和整理2001～2012年国审普通玉米杂交种及其双亲来源，研究每年国审玉米品种数量的变化趋势，对选育的杂交种在2个以上的亲本自交系进行统计，并分析这些自交系的来源。结果发现，普通玉米杂交种2006年审定的数量最多，2003年其次，2007年以后普通玉米杂交种的审定数量在10～20个。在对2001～2012年间国审玉米杂交种亲本来源的分析发现，共有39个亲本自交系组配2个及其以上杂交种，组配杂交种比较多的自交系依次为吉853>丹598>lx9801>昌7-2>京2416>丹340。

| Abstract: | The maize hybrids and their parental lines which approved by the nation from 2001 to 2012 were col-lected. The inbred lines which had been more than two hybrids were counted up and their pedigree resource was an-alyzed. The results showed that the number of approved hybrids in 2006 was most and the second was in 2003. The number of approved hybrids was between 10-20 after year 2007. Thirty-nine inbred lines were the parental lines of more than two hybrids approved. The leading lines were Ji853, Dan598, Lx9801, Chang7-2, Jing2416 and Dan340. |
