摘　　要：本试验是隆平高科种业西南区玉米审定“绿色通道”试验,采用完全随机区组设计,于2017年春在贵州省平坝区天龙玉米育种基地种植。试验材料是隆平高科种业提供的11个玉米杂交种。通过对11个玉米杂交种的产量性状和生物学性状的调查,分析其产量、产量性状、植株性状和抗性的综合表现,鉴定11个玉米杂交种在贵州中部地区的适应性,为品种审定提供参考。试验结果表明:11个杂交种的抗倒性、抗病性表现都比较好。隆平18、隆平15、隆平20、隆平14、隆平21、隆平17、隆平16、隆平22、隆平12、隆平19在产量上没有显著差异。其中隆平18、隆平14、隆平12、隆平16、隆平22在产量、产量性状和植株性状等方面表现较好,特别是隆平18的折合亩产达到578.68 kg/亩,比CK1(渝单8号)增产1.57%,比CK2(荃玉9号)增产19.69%,所以建议进入下一年的生产试验和多点试验。由于隆平13的产量最低,与其余10个杂交种、CK1、CK2相比差异显著,且产量性状表现不佳,因此建议淘汰。The experiment is a“green passage”test for corn from Longping High-Tech Agriculture.The experiment was completely randomized designed,and the 11 corn hybrids provided by Longping High-Tech Agriculture were planted in the spring of 2017 at Tianlong Corn Breeding Base in Pingba District,Guizhou Province.Through the investigation of the yield and the biological traits of the 11 corn hybrids,the comprehensive performance of yield,yield traits,plant traits and resistance were analyzed to determine the adaptability of the 11 corn hybrids in central Guizhou.The test results show that the 11 corn hybrids have good lodging resistance and disease resistance.Longping 18,Longping 15,Longping 20,Longping 14,Longping 21,Longping 17,Longping 16,Longping 22,Longping12,and Longping19 show no significant difference in yield.Longping 18,Longping 14,Longping 12,Longping 16,and Longping 22 perform well in terms of yield,yield traits and plant traits.The yield of Longping 18 has reached 578.68 kg/mu,which is higher than that of CK1(Yudan 8)by 1.57%and that of CK2(Quanyu 9)by 19.69%.Longping 18 is recommended to enter the next year’s production test.The yield of Longping 13 is the lowest,significantly different from the other 10 hybrids,CK1 and CK2,and the yield traits are not good,so it is recommended that the variety be eliminated.
