Progress Report Objectives (from AD-416): On-farm testing and proof-of-concept trials for the 2008-09 and 2009-10 wheat growing seasons for newly-developed bread wheat cultivars. Approach (from AD-416): Plant, maintain, examine, and harvest drill-strip size experiments on growers farms using standard varieties and newly-developed bread wheat cultivars. The research relates directly to inhouse objective 2 - Develop improved methods of marker-assisted selection, and apply markers in development of small grains cultivars. We have developed a full pipeline of germplasm, making 1000 crosses per year, resulting in 30,000 head rows per year and 40-70 new elite experimental lines per year. The emphasis of the program is on end-use quality of the wheat flour. PI confers with the sponsor by phone, email and in person. A research planning and results meeting is held in-person during August. A field day is arranged for the sponsor each year to jointly evaluate wheat lines in the field.

Progress Report Objectives (from AD-416): On-farm testing and proof-of-concept trials for the 2008-09 and 2009-10 wheat growing seasons for newly-developed bread wheat cultivars. Approach (from AD-416): Plant, maintain, examine, and harvest drill-strip size experiments on growers farms using standard varieties and newly-developed bread wheat cultivars. This research relates to inhouse Objective 1: Identify sources of resistance to foliar fungal pathogens and introgress resistance into adapted wheat. All of our North Carolina-adapted experimental elite hard wheats were also tested in Louisiana, Georgia, Kentucky, Virginia, Maryland, Indiana, Arkansas, Texas, Oklahoma, Nebraska, and Washington State. Preliminary results from those locations indicated that the two lines have wide- adaptation in the U.S. Our elite materials, as well as all of our early- generation lines were tested for Ug99 stem rust resistance in Kenya. We are the only program in the world that has combined 4 genes for resistance to stem rust into single lines. We have been able to do this by shuttling segregating wheat populations between North Carolina and Kenya. We do this by selecting types with good agronomic performance in North Carolina, then selecting within those for resistance in Kenya. We then conduct genotyping in North Carolina for identification of specific stem rust resistance genes.

Progress Report Objectives (from AD-416) On-farm testing and proof-of-concept trials for the 2008-09 and 2009-10 wheat growing seasons for newly-developed bread wheat cultivars. Approach (from AD-416) Plant, maintain, examine, and harvest drill-strip size experiments on growers farms using standard varieties and newly-developed bread wheat cultivars. This project is related to Objective 1 of the parent project: To identify sources of resistance to foliar fungal pathogens and introgress resistance into adapted wheat. The second year of this breeding project continued. Development and release of specialty wheats for the eastern U.S. Wheat varieties having bread wheat, end-use quality are needed for production in the eastern U.S. to serve as a local source of high protein flour for organic and artisan bakers. The hard red winter wheat lines ARS05-0241 and ARS07-0785 will be named and released to seedsmen in August 2011. These two new varieties follow the 2009 release of the hard red winter wheat �NuEast� and the hard white winter wheat �Appalachian White�. These wheat varieties were critical in the formation of an eight-bakery cooperative formed in Asheville, NC having the goal of locally-produced wheat, flour, and bread products. These wheat varieties also provided the thrust behind the formation of the non-profit organizations North Carolina Organic Bread Flour Project and Carolina Ground.

Progress Report Objectives (from AD-416) On-farm testing and proof-of-concept trials for the 2008-09 and 2009-10 wheat growing seasons for newly-developed bread wheat cultivars. Approach (from AD-416) Plant, maintain, examine, and harvest drill-strip size experiments on growers farms using standard varieties and newly-developed bread wheat cultivars. Significant Activities that Support Special Target Populations This project related to inhouse objective 2: Develop improved methods of marker-assisted selection and apply markers in development of improved wheat and oat. On-farm research included growing five experimental, hard wheat lines and appropriate check varieties on farmer�s fields in 11 locations in North Carolina. Locations were in the counties of Ashe, Beaufort, Cumberland, Haywood, Lenoir, Moore, Robeson, Rowan, Tyrrell, Wake, and Washington. These counties span North Carolina from east to west, and north to south. For the 2008-09 growing season, quality of hard wheat varied from poor to excellent. Poorer quality was found in counties in the southern parts of the State, while excellent quality grain quality was found in north, east, and western counties. Progress was monitored with the cooperator by phone and email throughout the growing season. Field locations were visited 6 times during the growing season.
