Abstract:

‘Yongyou 988’ is a new maize variety bred by Hebi Academy of Agricultural Sciences with T1932 from European flint line as the female parent and ‘Xun 856’ as the male parent, and it was approved by the nation for Huang-Huai-Hai summer maize region in 2021. In this study, the breeding process, parent source and characteristics, yield performance, stress resistance, disease resistance and quality analysis of the variety were analyzed. The study proposed that in variety breeding, we should highlight the exploration and utilization of excellent germplasm resources, strengthen adversity selection and improve ecological adaptability of the varieties, so as to breed a new maize variety with high yield and quality, wide adaptability, density tolerance and strong stress resistance.

Key words: maize, ‘Yongyou 988’, germplasm resource, stress resistance, adaptability
