摘　　要：利用2004-2007年山东省玉米区域试验资料,对通过审定高产玉米杂交种的农艺性状、抗病性和品质等性状进行了综合分析。提出今后高产玉米育种应注意穗长和千粒重的遗传改良以及抗青枯病的选择。Based on the data of area experiments during 2004 -2007, the agronomic characteristics, disease resistance and qualities of the high-yield maize hybrids authorized in Shandong Province were analyzed. More efforts should be made on the genetic improvement of spike length and 1000-grain weight as well as the effective screening the cuhivars with resistance to bacterial wilt.
