In order to clarify the high and stable capacity of yield, and quality stability of semi-winter wheat varieties (lines) with high yield potential in Anhui Province, a randomized block design was adopted in this study from 2022 to 2023 in six test sites: Taihe, Sixian, Suixi, Wuyang, Yingshang, and Yingzhou. The test materials were the varieties (lines) with significantly higher yield than the control varieties in the regional and production experiments in Anhui Province from 2018 to 2022, and the yield, yield components, and quality of the tested materials were analyzed. The results showed that location, variety (line) and their interaction effects had a significant impact on yield, yield components (except spike number) and quality, the location and its interaction effect with varieties were the main sources of variation of yield and yield components. The yield and spike in Taihe were significantly higher than those in other sites, reaching 10 210 kg·hm-2 and 7.74×106 per hm2, respectively, and the spike weight in Yingzhou was the highest (1.52 g). Among the tested materials, Annong 188 and Anke 1803 had high yield, with average yield of 9 572 kg·hm-2 and 9 407 kg·hm-2. Anke 1803 and Wanke 1838 exhibited higher yield stability, and Anong 188 had the widest adaptation range. When the yield was lower than 10 500 kg·hm-2, it was significantly positively correlated with the number of spikes and spike weight, as yield increased further, the higher yield was mainly attributed to the increase of spike number. The stable yield of wheat mainly depended on the stability of panicle grains. Location was a major factor for quality variation. The quality of wheat in Yingshang was significantly higher than that in other locations, and the lowest in Sixian. Wansu 21 showed the best quality, and Anke 1803 showed the best quality stability. In summary, the synergy of high yield, stable yield and high quality of semi-winter wheat varieties (lines) in Anhui Province was weak, and targeted cultivation technologies should be formulated according to local ecological conditions in the future to achieve the synergistic improvement of wheat yield, quality and stability.
