Abstract: Based on the wheat yields from the National Huang‑Huai Winter Wheat Southern Region Trial in 2020—2021 and 2021—2022，the high and stable yield potential of wheat cultivar Yutong 112 was comprehensively evaluated using the high‑stability coefficient（HSC） and the GGE biplot model.Inaddition，the genetic characteristics of Yutong 112 were thoroughly elucidated using the wheat 0.1Kfunctional chip，so as to provide a theoretical basis for its production application and parental utilization.The results showed that the average yield of Yutong 112 in 2020—2021 and 2021—2022 was 8 968.91 kg/ha，which was 6.12% higher than that of the control variety Zhoumai 36，and 86% of its test sites showed yield increases.The average HSC was 85.34%.GGE biplot analysis indicated that Yutong 112 exhibited excellent productivity，stability，and wide adaptability，closely approximating an ideal cultivar，and demonstrated high promotion potential in the Huang‑Huai Winter Wheat Region.The molecular marker detection results indicated that Yutong 112 pyramided ten QTLs（QYrsn.nwafu‑1BL，QYrxn.nwafy‑1BL，QYrqin.nwafu‑2AS，QYrqin.nwafu‑2AL，QYrqin. nwafu‑2BL，QYr.nwafu‑3BS，QYrsn.nwafu‑3DL，QYr.nwafu‑4BL，QYrsn.nwafu‑6BS，and QYrqin.nwafu‑6BS）and five genes（Yr30，Yr82，Yr29，Yr75，and Yr78）related with stripe rust resistance，two QTLs related with Fusarium head blight resistance（QFhb.hbaas‑5AL and QFhb.caas‑5AL），three genes related with leaf rust resistance（Lr13，Lr67，and Lr46），one gene related with powdery mildew resistance（Pm12），seven genes related with grain size and grain weight（TaGS2‑B1，TaGS1a，TaSus1‑7B，TaCwi‑A1，TaGS5‑A1，TaGW2‑6A，and AGP‑L‑1B），one QTL related with grain size（QG1‑4A），and four genes related with plant height（RHT‑8，Rht‑D1，Rht24_AP2，and Rht24_FAR）.
