以湖北省五峰土家族自治县试验点为例,对2009-2016年国家西南玉米（Zea mays L.）区试和湖北省山区组玉米区试参试品种的抗逆性进行了比较分析。2009-2016年湖北省山区组玉米区试参试品种在抗逆性方面,多项病害抗逆性性状表现均优于或明显优于国家西南玉米区试参试品种。说明湖北省山区组玉米区试参试品种选育者对湖北省山区玉米的抗逆性选择方面有更充分的认识和更强的针对性,取得了显著的成绩,应予充分肯定。选育者根据自身具体情况,着眼于不同的生态区域,选育适宜不同生态区域种植的具有较强抗逆性的玉米品种是一种很好的目标定位。
Taking the experimental site in Wufeng Tujia Autonomous county of Hubei as an example,we compared and analyzed the stress resistance of tested maize varieties from the Hubei Provincial Maize Variety Regional Trial for Mountainous Area and the National Maize Variety Regional Trial for southwest Area between 2009 and 2016. Results showed that during these years,the mean performance of multiple diseases resistance of the varieties from Hubei Provincial Maize Regional Trial for Mountainous Area was better or much better than the varieties from National Maize Regional Trial for southwest Area. It indicated that the maize breeders in Hubei understood the local diseases situation better and worked more efficiently. It also suggested that it is possible to develop maize varieties with good diseases resistance for certain specific ecological maize planting area.
