This study explores the effects of climate change on the agronomic traits of winter wheat in Yangzhou over recent years, providing a theoretical foundation for breeding new winter wheat varieties adapted to climate change. Utilizing wheat agronomic trait data and meteorological data from 2003 to 2023 in Yangzhou, we statistically analysed trends in wheat agronomic traits and climate change, and performed correlation analysis. The findings reveal that in recent years, both precipitation and temperature during wheat growth stage in Yangzhou have risen, while sunlight hours have decreased. The agronomic traits of wheat, including the number of effective spikes, grains per spike, and yield per unit area have improved, while the thousand grain weight has decreased. In light of this analysis, the increased frequency of extreme weather events during the wheat growth phase due to global warming means that wheat grain filling is likely to face high-temperature stress, potentially shortening the grain filling stage and subsequently impacting the thousand grain weight and limiting yield improvements. Consequently, breeding for future wheat varieties should prioritize grain filling characteristics and stable grain weight.
