摘要：玉米是天水市的主要糧食作物之一。為了篩選適宜在天水旱作區種植的優良玉米品種，2021年對從當地收集的27個玉米品種進行比較試驗。結果表明，27個參試玉米品種在當地氣候條件下均能正常成熟。以優迪919折合產量最高，為13 014.29 kg/hm2，較對照品種先玉335增產11.08%;玉源7879次之，折合產量為12 995.24 kg/hm2，較對照品種先玉335增產10.92%;翔玉218居第3位，折合產量為12 941.27 kg/hm2，較對照品種先玉335增產10.46%;登海182、德單1403、龍博士7號、翔玉329、登海9號、金凱3號折合產量也較高，分別較對照品種先玉335增產9.31%、9.05%、8.56%、8.16%、8.12%、7.56%。這9個品種較對照品種先玉335增產幅度均在7.50%以上，且農藝性狀、經濟性狀優良，總體表現相對較好，可在天水市旱作農業區種植。

Abstract： Maize is one of the main food crops in Tianshui. To select suitable maize variety used in dry farming area of Tianshui， 27 maize varieties collected regionally were used in 2021 to conduct comparison trial on maize varieties. Results showed that all varieties could reach maturity under the climate condition of Tianshui， average yield of Youdi 919 was the highest， i.e.? ? ? ?13 014.29 kg/ha， which was 11.08% higher compared with that of the control Xianyu 335， followed by Yuyuan 7879（average yield? 12 995.24 kg/ha， 10.92% higher than that of the control） and Xiangyu 218（average yield 12 941.27 kg/ha， 10.46% higher than that of the control）， averaged yield data of other varieties such as Denghai 182， Dedan 1403， Longboshi 7， Xiangyu 329， Denghai 9 and Jinkai 3 also showed ideal numbers， which were 9.31%， 9.05%， 8.56%， 8.16%， 8.12% and 7.56% higher compared with that of the control， respectively. Yield increase rates of the above 9 varieties were all above 7.50% compared with the average yield of control， agronomic and economic traits， overall performance of the 9 varieties were ideal， therefore， these 9 maize varieties are considered suitable for dry farming area of Tianshui.

Key words： Maize; Variety comparison; Yield; Tianshui dry farming area
