Abstract:

In order to select suitable silage maize varieties in western Henan, we took ‘Zhengqing 3’, ‘Jingke 932’, ‘Chuandan 99’, ‘Zhengdan 958’ and ‘Yayu 8’ (control treatment) as materials, analyzed variety adaptability by exploring the photosynthetic and fluorescence characteristics of different varieties at tasseling silking stage in combination with the final fresh and dry forage yield and kernel yield. The results showed that ‘Zhengdan 958’ and ‘Chuandan 99’ had good photosynthetic performance, and ‘Chuandan 99’ had good chlorophyll fluorescence performance and high fresh forage yield. ‘Zhengdan 958’ had high kernel yield. Therefore, ‘Chuandan 99’ is a suitable silage maize variety for planting in western Henan, and ‘Zhengdan 958’ is a dual-purpose maize variety suitable for kernel harvesting and silage in western Henan.
