摘要
为探究关中地区不同玉米品种的农艺性状和经济性状表现,筛选适合关中地区种植的玉米品种,2023年在宝鸡市凤翔区以壳盛5063、强盛370、强盛58、迪卡653、睿德268、迪卡698、伟科818为供试品种,观察分析这7个品种的株高、穗位高、茎粗以及穗重、行粒数、百粒重等相关性状表现。结果表明,强盛370与睿德268的地上部分植株鲜重、雄穗主轴长、鲜穗重、穗干重、穗芯重、穗长、行粒数等性状表现居前两位,伟科818的茎粗、穗粗、穗行数最高,强盛370、睿德268、伟科818的产量居前3位,强盛370、睿德268、伟科818等3个品种在关中地区推广价值较大。
To explore the agronomic and economic characteristics of different corn varieties in Guanzhong region,and screen those best suited for Guanzhong region,a comparative experiment was conducted in 2023 in Fengxiang District of Baoji,Shaanxi Province.Seven varieties,including‘Kesheng 5063’,‘Qiangsheng 370’,‘Qiangsheng 58’,‘Dika 653’,‘Ruide 268’,‘Dika 698’,and‘Weike 818’were observed and analyzed for plant height,ear position height,stem diameter,ear weight,number of grains per row,and hundred-grain weight.The results showed that‘Qiangsheng 370’and‘Ruide 268’ranked among the top two in traits such as aboveground plant fresh weight,main axis length of male tassels,fresh ear weight,dry ear weight,ear core weight,ear length,and grain number per row.‘Weike 818’exhibited the greatest stem thickness,ear diameter,and number of kernel rows.In terms of yield,‘Qiangsheng 370’,‘Ruide 268’,and‘Weike 818’ranked among the top three and demonstrated significant potential for large-scale extension in the Guanzhong region.
