The Impacts of Nitrogen Accumulation, Translocation, and Photosynthesis on Simultaneous Improvements in the Grain Yield and Gluten Quality of Dryland Wheat

The effects of nitrogen (N) accumulation and translocation on photosynthesis have been widely reported, while the impacts N accumulation, translocation, simultaneous improvements in grain yield gluten quality dryland wheat still remain unclear. For this reason, relationships between photosynthesis, use efficiency (NUE), related traits yield, quality, 11 representative genotypes 2018–2021 cropping years were examined. results show that weights per spike accounted for 58.7% 42.4% genetic variations protein contents, respectively. Meanwhile, at maturity stage caused a 49.5% variation contents. index MY26 NM101 significantly decreased with decrease number 2018–2019 season. precipitation reduced by 53.8% 2019–2020 season, resulting increased 13.0%. CY25 showed high without reducing due to net photosynthetic rate, big size, large leaf area index, spike, Our indicated increasing weight individual via genotype selection rate simultaneously improved wheat. Moreover, effect genotype–environment interaction was regulated canopy senescence, affected source supply associated sink demands relation under soil conditions.
