山西省春播中晚熟玉米杂交种评价

Comprehensive evaluation on spring sowing middle-late-maturity hybrid maize varieties of Shanxi province

为加快玉米全程机械化生产进程,筛选抗性好、产量高、收获期含水率低的品种,试验对山西省26个春播中晚熟玉米杂交种进行综合分析与评价,以期筛选出适宜机械化直收籽粒的品种。结果表明:综合抗性好的品种有11个,分别是郑单958、太玉339、诚信5号、强盛101、瑞普908、中种8号、吉单261、种星618、大丰26、大丰30、屯玉99;产量高同时收获期含水率低的品种有8个,分别是瑞普908、先玉335、太玉339、利民33、大丰30、中种8号、良玉188、华农138,这8个品种可作为山西省春播中晚熟区玉米全程机械化生产的前期推广品种。

In order to speed up the entire producing mechanization of maize,resistant varieties of high production and low moisture content in harvest time were screened for.In this article 26 spring sowing middle-late-maturity hybrid corn varieties of Shanxi Province were comprehensive evaluated to screen maize hybrids of suitable for mechanical harvesting. The results showed that eleven varieties showed better resistance,which were Zhengdan958,Taiyu339,Chengxin5 hao,Qiangsheng101,Ruipu908,Zhongzhong8 hao,Jid-an261,Zhongxing618,Dafeng26,Dafeng30 and Tunyu99,respectively;8 varieties showed better high-yield and low water content in harvest time,which were Ruipu908,Xianyu335, Taiyu339,Limin33,Dafeng30,Zhongzhong8 hao,Liangyu188 and Huanong138,respectively.The eight varieties can be used as main maize cultivars of spring sowing middle-late-maturity during the entire producing mechanization in Shanxi province.
