摘要

[Objective] To study main agronomic traits of 30 corn new combination ,in order to provide theoretical basis for breeding high yield corn varieties.[Method]The main agronomic traits of some main maize varieties in Zunyi were studied by using the ratio design.[Result]The height of each cultivar was between 219.00 cm and 286.00 cm,the height of ear was between 78.50 cm and 141.00 cm,the spike length was between 15.05 cm and 22.75 cm,and the panicle was between 4.10 cm and 6.00 cm.The number of rows was between 13.70 and 17.80,the number of rows was between 26.30 and 40.15, the bald tip was between 0.50 cm and 3.07 cm.[Conclusion]Moderate varieties are Luxin 23,Zhengda 999,Tenglong 1,Baoyu 007,Fuchun 339,Jinyu 818,Tianchi No.2,Huafeng 99,Haihe 23,Anyu 2166,Zhuoyu 818,Tianyu 3000,Pudan No.6,Chuanyu 13.%[目的] 研究30个玉米新组合的主要农艺性状,以期为玉米高产育种提供理论依据.[方法]运用间比法排列设计,研究遵义市部分主推玉米品种的主要农艺性状.[结果]各个品种株高在219.00~286.00 cm;穗位高在78.50~141.00 cm;穗长在15.05~22.75 cm;穗粗在4.10~6.00 cm;穗行数在13.70~17.80行;行粒数在26.30~40.15粒;秃尖在0.50~3.07 cm.[结论]综合考虑,株高、穗位、果穗适中的品种有露新23、正大999、腾龙1号、宝玉007、富春339、金玉818、天池2号、华丰99、海禾23、安玉2166、卓玉818、天玉3000、濮单6号、川玉13.
