Effect of wheat quality traits and glutenin composition on tortilla quality from the USDA Southern Regional Performance Nursery

The popularity of wheat flour tortillas is spreading throughout the world and has become one highest-selling bread products. USDA Southern Regional Performance Nursery (SRPN) serves as largest wheat-growing region in USA, but tortilla quality germplasm SRPN remained unknown. This study investigated kernel traits, dough rheological properties, parameters, glutenin composition 131 lines from 1995 to 2007 SRPN. high molecular weight subunits (HMW-GS) wheat–rye 1RS translocation status these were also detected. A wide variation traits was observed among lines. Association analysis showed that increased protein content gluten strength significantly decreased diameter improved shelf life terms 2-D extensibility parameters (P < .001). group with acceptable (both >165 mm day 16 flexibility score >3.0) had medium strength. Compared 5 + 10 non-1RS translocation, those 2 12 generally lower life, higher specific volume 0.01).
