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。
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/hm^2 （increasing by 4.1%, ranking No.8） in prepare trials of middle-late maturing maize （resistant to high density） in Shanxi Province in 2011;the average yield was 13608.0 kg/hm^2 （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/hm^2 （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 , multi-resistance （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/hm^2. The application prospect of‘Zhongdi 88’was better.
