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.
