Interpretive Summary: These results are used by wheat breeders in the eastern U.S. to determine the adaptability of hard wheats to regions of the eastern U.S.

Technical Abstract: The purpose of the Uniform Bread Wheat Trial (UBWT) is to evaluate hard endosperm, bread quality, winter habit cultivars and advanced lines for adaptation to the high rainfall, humid environments of the eastern United States. The entries in this 3rd UBWT were selected from public and private breeding programs in the southern and central Great Plains. A total of 25 entries were included in the trial. There were nine testing locations with one in Georgia, three in North Carolina, three in Virginia, one in Kentucky, and one in Pennsylvania. Over all locations, the hard wheat line TX99D4478 yielded statistically equal (P=0.05) to the highest yielding soft wheats. The highest yielding hard wheats were all experimental lines (TX99D4478, TX99D4441, TX98D1170, and TX96D1073). The top five released, hard wheat cultivars for grain yield over all locations were 'Lakin', and 'TAM 302'. At six individual locations (Plains, GA, Salisbury, NC, Painter, VA, Warsaw, VA, Lexington, KY, and State College, PA), there were hard wheats that had grain yields equal to, or higher than, the soft wheats. Test weights were relatively low at all locations except Salisbury, NC. Several hard wheats had test weights comparable to or higher than the soft wheats. Heading date, height, and lodging scores varied widely among all entries. There was also wide variation for resistance to powdery mildew, glume blotch, scab, leaf rust, and soilborne mosaic. The kernel hardness scores were consistent and true-to-type across all locations tested with the exception of the HRWs
