Abstract:

Mechanized grain harvesting of maize can greatly save labor cost, which has important significance for improving the economic benefits of maize planting. However, there are insufficient studies on maize varieties suitable for mechanized grain harvesting. This study aims at breeding maize varieties with density tolerance, multi-resistance and suitable for mechanized grain harvesting. A new variety ‘Xundan 1668’, which is suitable for mechanized harvesting and summer sowing areas in Henan and Shandong, was selected and identified in multi-ecological areas for many years. It was approved by the Crop Variety Approval Committee of Shandong Province and Henan Province in 2019 and 2020, respectively. Compared with that of the control variety, the average yield of ‘Xundan 1668’ was increased by more than 5%. The variety has lodging resistance and fast dewatering and is suitable for mechanized grain harvesting, which can be a material foundation for improving the mechanized harvesting degree of maize, reducing labor cost and ensuring food security.

Key words: maize, mechanized grain harvesting, ‘Xundan1668’, variety breeding, cultivation techniques
