玉米展示品种比较试验

Comparative Experiment of Maize( Zea mays L.) Display Varieties

[目的]为鹤壁地区合理种植玉米(Zea mays L.)新品种提供科学依据。[方法]对12个玉米展示品种(登海602、登海601、洛玉4号、滑986、浚单20、粟玉2号、农乐988、中科11、郑单958、鲁单9002、蠡玉35、金裕8号)的田间观察记载情况、室内考种及产量等进行比较分析,以郑单958为对照。[结论]登海602、浚单20、中科11抗病抗倒性强、产量高、综合性状表现好,分别比对照增产10.4%、4.5%和1.1%,适宜在鹤壁市大面积推广种植。[结论]该研究可为鹤壁地区玉米高产优质栽培提供品种依据。

[ Objective ] The aim was to provide a scientific basis for reasonably planting new maize varieties in Hebi Area. [ Method ] The field observation recoids status, indoor analysis and yield of 12 maize display varieties（ Denghai 602, Denghai 601, Luoyu No. 4, Hua 986, Jundan 20, Suyu No. 2, Nongle 988, Zhongke 11, Zhengdan 958, Ludan 9002, Liyu 35, Jinyu No. 8） were compared and analyzed, taking Zhengdan 958 as control. [ Result ] Denghai 602, Jundan 2 and Zhongke 11 had strong resistance to disease and lodging, high yield and good comprehen- sive traits, their yield increased 10.4%, 4.5%, 1.1% respectively than control, so they were suitable for promotion and planting in a large scale in Hebi Area. [ Conclusion] The study provides a variety basis for maize high yield and good quality cultivation in Hebi Area.
