2018年山西省特早熟区组玉米品种比较试验

Comparative Test of Maize Varieties in Super Early Maturing District of Shanxi Province in 2018

为了筛选出适宜在山西省内种植的高产稳产、质优、多抗、熟期适中的玉米新品种,2018年以并单16作为对照,采用随机区组设计,在山西省农业科学院旱地农业研究中心阳曲县试验基地对18个玉米新品种进行区域试验。结果表明,山西省春播特早熟Ⅱ区太原试点玉米区域试验中,辉玉826、尧玉656、德朗117、并单1605、大智535、长单815这6个参试品种产量较对照并单16分别增产11.52%、10.09%、8.85%、8.71%、8.20%、7.17%,其综合抗性好,建议进一步进行多点生产试验,待品种审定后在特早熟区域内示范推广。

To screen out new maize varieties with high and stable yield,high quality,multi resistance and moderate maturity suitable for planting in Shanxi province,in 2018,18 new corn varieties were tested in Yangqu county experimental base of Dryland Agricultural Research Center of Shanxi Academy of Agricultural Sciences,by using the techniques of random design,and taking Bingdan 18 as the control.The results showed that compared with the control Bingdan 16,the yield of Huiyu 826,Yaoyu 656,Delang 117,Bingdan 1605,Dazhi 535 and Changdan 815 increased by 11.52%,10.09%,8.85%,8.71%,8.20%and 7.17%,respectively,and their comprehensive resistance was good.It was suggested that further multi-point production test should be carried out and the super early maturing should be carried out after variety approval demonstration and promotion in the region.
