Among the major crops grown in the U.S. Southeast Region, soft red winter wheat (SRWW; Triticum aestivum L.) contributes significantly to wheat growers and the industry. However, wheat is challenged by many stresses, resulting in substantial yield and quality losses. Therefore, developing new cultivars with high yield potential, resistance to major pests in the Southeast, and good quality is warranted. Consequently, this is the main goal of the SRWW breeding programs at the University of Georgia (UGA) and the Southeastern UNiversities GRAINS programs. The SRWW cultivar ‘GA 09129‐16E55’ (Reg. No. CV‐1226, PI 698827) is a well‐adapted wheat developed and released by the UGA College of Agricultural and Environmental Sciences in 2019. GA 09129‐16E55 is overall well adapted to the Southeast and, specifically, to conditions in Georgia. It is a high‐yielding cultivar with very good resistance to most dominant diseases, including leaf rust (caused by Puccinia triticina Erikss.), stripe rust (caused by P. striiformis Westend.), powdery mildew (caused by Blumeria graminis ), and soil‐borne wheat mosaic virus . The reaction of GA 09129‐16E55 to Fusarium head blight (caused by Fusarium graminearum Schwabe) is reflected in lower levels of disease severity and deoxynivalenol toxin. It also showed moderate field susceptibility to Hessian fly [ Mayetiola destructor (Say)]; under greenhouse conditions, it was resistant to B and C biotypes but susceptible to O and L biotypes. GA 09129‐16E55 has good grain volume weight and good milling and baking quality as an SRWW.
