广西忻城县玉米品种比较试验

A comparative study of some corn varieties in Xincheng county of Guangxi

为筛选适宜广西忻城县种植的高产、高抗玉米新品种,于2009年在忻城县城关镇畔水村进行不同玉米品种比较试验。结果表明:品种正大999、瑞恒269、迪卡008、太平洋98、南校201表现生长势强、高产、抗病、抗虫、抗逆性强等特点,可在忻城县推广种植;品种瑞恒666、玉美头168种植表现一般,且较对照迪卡007增产不明显,纹枯病发生较重,需进一步种植观察;东单80籽粒产量较低,抗病、抗逆性差,绿城133表现果穗短小、产量低,这2个品种均不宜在忻城县推广。

The present experiment has been conducted to screen some new corn varieties with high yield and resistance suitable for planting in Xincheng county of Guangxi.A comparative test of corn varieties was undertaken in Panshui village,Chengguan town,Xincheng county in 2009.The varieties Zhengda 999,Ruiheng 269,Dika 008,Taipingyang 98 and Nanxiao 201 showed strong growth vigor,high yield and strong resistance to disease,insect and abiotic.These varieties were found suitable for planting widely in Xincheng county.Varieties Ruiheng 666 and Yumeitou 168 performed normally in the field,the increase in yield was not significant as compared to control variety Dika 007.The two varieties affected severely by rice sheath blight disease,and need to be investigated further.Variety Dongdan 80 showed low yield and lesser resistance to biotic and abiotic stresses,and variety Lücheng 133 was characterized by short ear length and low yield,both of these varieties were not suitable for planting in Xincheng county.
