摘　　要：以大庆地区种植的15个玉米杂交种为材料,在4个不同地点进行品种筛选试验。结果表明:试验地点、品种和地点×品种均存在显著的差异。4个地点产量均值前5位分别为冀单9号、江单1、江单3、长单506和长单228,适合大庆地区种植。品种久龙5号、吉单46和久龙6号的回归系数接近于1,这3个品种产量稳定性较好。品种江单1、江单3、安玉13、德单8、久龙12、齐单6的产量和环境指数不存在线性回归关系。Using 15 maize varieties of planting in Daqing as material,the screening experiments were carried out in 4 typical ecotype locations. The results showed that there were significant difference among test locations,varieties and locations ×varieties. The top 5 of mean yields in 4 locations were Jindan 9,Jiangdan 1,Jiangdan 3,Changdan 506 and Changdan 228,respectively,all of which were suitable to plant in Daqing. The regression coefficient of Jiulong 5,Jidan 46 and Jiulong 6 were approach to 1,and these varieties had good yield stability. There was no linear regression relationship between yield and environ- mental index of Jiangdan 1,Jiangdan 3,Anyu 13,Dedan 8,Jiulong 12 and Qidan 6.
