Interpretive Summary: The development and deployment of superior and regionally adapted soft red winter wheat (SRWW) cultivars is an essential element to enhance and sustain wheat production in the SE US. SRWW cultivars should have high yield, good resistance levels to predominant pests, and acceptable milling qualities to maximize value in regional markets. To facilitate development of new SRWW cultivars, breeding programs in the SE region (The University of Arkansas, University of Florida, the University of Georgia, Louisiana State University Agricultural Center, North Carolina State University, and Texas A&M University) collaborate as part of the “Southeastern University GRAINS” (SUNGRAINS). The SRWW GA JT141-14E45 (PI 689519) was developed at the UGA and released by the UGA Agricultural Experiment Station in 2017 in collaboration with the SUNGRAINS breeding programs.

Technical Abstract: In Georgia (GA) and the South East (SE) regions of the USA, acreage of soft red winter wheat (SRWW) (Triticum aestivum L.) has decreased in recent years. There is an urgent need to release new cultivars with high yield potential, resistance to yield-limiting diseases and insects, and with good baking quality to maximize value in regional markets. To address this, the SRWW breeding program at the University of Georgia (UGA), in collaboration with the SUNGRAINS breeding programs, developed ‘GA JT141-14E45’ (PI 689519), a SRWW cultivar released by the UGA College of Agricultural and Environmental Sciences and licensed to AGSouth (AGS) Company as AGS 3030. GA JT141-14E45 is widely adapted to the SE US having high yield, good resistance to diseases such as leaf rust (caused by Puccinia triticina Erikss.); stripe rust (caused by Puccinia striiformis Westend); powdery mildew (Erisyphe graminis); soil-borne wheat mosaic virus (SBWMV) and to current biotypes of Hessian fly (Mayetiola destructor (Say)). It has good resistance to Fusarium head blight (FHB) or scab [caused by Fusarium graminearum Schwabe]. GA JT141-14E45 has good grain volume weight and acceptable milling and baking quality. GA JT141-14E45 was derived from the cross of ‘AGS 2026’ /‘Jamestown’. Jamestown (PI 653731) was used in the cross mainly for its resistance to FHB (FHB QTL 1A-Neuse and 1B-Jamestown). AGS 2026 is a UGA cultivar released in 2007 with very good rusts disease resistance (Yr17/Lr37/Sr38), Hessian fly resistance (H13), and excellent yield.
