皖北地区玉米品种筛选试验

为筛选出适合皖北种植的最佳玉米品种,在大田生产条件下,2019—2020年收集目前皖北种植面积较大的6个品种开展了试验,并对每个品种的抗病性、抗倒性、稳产性、产量及2年气象因子进行了分析。结果表明,2年试验,中科玉505综合抗性、稳产性及丰产性表现最佳,特别是高抗茎腐病和高抗南方锈病;郑单958抗倒性强,但南方锈病重。2年同期气候差异较大,2020年青枯病和南方锈病暴发,部分品种减产幅度较大,但中科玉505综合抗性、丰产性最好。

Screening test of Maize Varieties in Northern Anhui

Objective] to screen the best maize varieties suitable for planting in Northern Anhui Province. method] six varieties with large planting area in Northern Anhui were collected under field production conditions. The disease resistance, lodging resistance, stable yield, yield and meteorological factors of each variety were compared. result] in the two-year experiment, zhongkeyu 505 showed the best comprehensive resistance, stable yield and high yield, especially high resistance to stem rot and southern rust, and Zhengdan 958 to southern rust It has strong reversibility, but severe rust in South China. Conclusion] the climate in the same period of two years is quite different. Bacterial wilt and southern rust will break out in 2020, and the yield of some varieties will be greatly reduced. Zhongkeyu 505 has the best comprehensive resistance and high yield,
