Interpretive Summary:

Technical Abstract: A mixograph (10-g flour) (MIXO) has greatly contributed to the hard winter wheat (HWW) breeding programs in screening early-generation lines based on mixing quality. Although a farinograph provides similar data and is used by industry worldwide, it has not been used for breeding programs, due to its large flour requirement (50-g) and longer testing time. The Farinograph® E (FARINO), can be used with the standard test (63/min) as well as at other variable speeds. In addition, a mini-mixing bowl (10-g flour) is currently available. We investigated mixing quality of 4 HWW (6.9, 12.6, 12.7, and 14.8% flour protein) with a FARINO at the 63, 75, 88, and 100/min mix speed and a MIXO at the 88/min speed. Water absorption (WA) increased (6.2% on average) whereas mix-time (MT), stability, and the time to break decreased (36, 60, and 32%, respectively) with an increased mix speed from 63 to 100/min (59%). The WA and MT of the 4 flours averaged 64.9% and 6.84 min for the FARINO (at 88/min), whereas 62.3% and 3.30 min for the MIXO, respectively. The FARINO-WA was significantly correlated with bake-WA and bread volume at all 4 speeds but better at the higher speed (88 and 100/min), which was also significantly correlated to MIXO-WA. Although the average FARINO-MT was still about 180% of MIXO-MT even at the 100/min with much thinner curve, the reduction of MT by 36% shows a potential use for breeding programs.
