摘要Salt and saline-alkaline stress seriously threaten crop pro-duction and food security worldwide (Yang and Guo, 2018). Identifying genes that confer tolerance to these con-ditions without yield penalty would help mitigate this problem through molecular breeding (Liang et al., 2023; Sahu and Liu, 2023). Although numerous stress-tolerance genes have been identified, their application potential in molecular breeding has rarely been confirmed through multi-year and multi-site field trials. We previously identified the wheat (Triticum aes-tivum) salt-tolerance gene TaCHP (TraesCS7D02G545700), encoding a Cys-, His-, and Pro-rich zinc finger protein (Li et al., 2010). Here, we report that overexpressing TaCHP stably enhanced wheat yields in saline-alkaline fields in a multi-year and three-site field trial, pointing to the potential of this gene for improving saline-alkaline tolerance in wheat via molecular breeding.
