| 摘 要： | 利用2002—2004年山东省玉米区域试验资料,通过对高产玉米品种生育期、株高、穗位高、穗长、穗行数、穗粒数和千粒重等指标进行综合分析,以此确定山东高产玉米育种最佳选育目标,为指导高产玉米育种提供借鉴和参考。研究结果表明:山东高产玉米育种综合选育目标为生育期100.1～104.0d,株高250.1～270.0cm,穗位高110.1～120.0cm,穗长17.1～19.0cm,穗行数14.6～15.5行,穗粒数520.1～560.0粒,千粒重330.1～350.0g。

| Abstract: | The optimal breeding characters of high-yielding maize were established based on those index of growing period, plant height, spike position and length, number of spike rows and grains and grain weight, and data of area experiments on maize breeding in Shandong Province during the year of 2002-2004, and providing some references for guiding the breeding of high-yielding maize in Shandong Province. The results showed that the integrate characters of maize breeding were growing period of 100.1~104.0 days, plant height of 250.1~270.0cm, and for the spike, 110.1~120.0cm in position, 17.1~19.0cm in length, 14.6~15.5 rows, 520.1~560.0 grains and 330.1~350.0g per 1000 grains in weight. |
