摘要： 为了选育适应性广、综合农艺性状优良、产量高的中晚熟耐密玉米新品种，山西省农业科学院玉米研究所以自选系M3-11为母本、D2-7为父本，于2008年选育而成‘中地88’。以‘先玉335’为对照，2011年‘中地88’参加山西省玉米中晚熟耐密组预备试验，平均产量为13815.0 kg/hm2（增产4.1%、排第8位）；2012—2013年参加山西省玉米中晚熟耐密组区域试验，平均产量为13608.0 kg/hm2（增产6.6%、排第4位）；2013年参加山西省玉米中晚熟耐密组生产试验，平均产量为12693.0 kg/hm2（增产6.8%，排第4位）。‘中地88’具有高产、优质、多抗（高抗玉米矮花叶病，中抗粗缩病、大斑病和茎腐病，感丝黑穗病、穗腐病）、耐密的优点，淀粉含量74.0%，属高淀粉品种，平均产量达13372.0 kg/hm2，开发应用前景乐观。

Abstract: In order to breed a new variety (resistant to high density) of middle- late maturing maize with extensively adaptability, good characters and high yield,‘Zhongdi 88’was bred with M3-11 (female) and D2-7 (male) by Maize Research Institute of Shanxi Academy of Agricultural Sciences at Xinzhou City in 2008.With‘Xianyu 335’as contrast, the average yield of‘Zhongdi 88’was 13815.0 kg/hm2 (increasing by 4.1%, rankingNo.8)inpreparetrialsofmiddle-latematuringmaize(resistanttohighdensity)inShanxiProvincein 2011;the average yield was 13608.0 kg/hm2 (increasing by 6.6%, ranking No.4) in area trials of middle-late maturing maize (resistant to high density) in Shanxi Province during 2012-2013; the average yield was 12693.0 kg/hm2 (increasing by 6.8% , ranking No.4 ) in production trials of middle- late maturing maize (resistant to high density) in Shanxi Province in 2013. This variety‘Zhongdi 88’had high yield, good grain quality , multiresistance (high resistance to dwarf mosaic virus of maize; resistance to rough dwarf disease, leaf blight and stalk rot; sense of head smut and ear rot), resistance to high density. The starch content of it was 74.0%. The average yield was 13372.0 kg/hm2. The application prospect of‘Zhongdi 88’was better.
