About the Nebraska Wheat Quality Data
This file contains the results of end-use quality analyses of
named cultivars grown within the state of Nebraska during the time
period 1977-1991. Quality assays were performed in the University
of Nebraska Wheat Quality Laboratory, Lincoln, Nebraska. Multiple
observations are included for most cultivars. Observations were
derived from numerous breeding nurseries. The control cultivar for
all nurseries was 'Scout 66'. Data are best interpreted by making
comparisons with the Scout 66 control from each respective nursery.
Samples with long Mixograph and Bake mix times are generally
considered to bear strong doughs. The following variables are
included:
variety = cultivar
year = harvest year
nursery = experimental or breeding test nursery
flour yield = % of grain derived as flour after milling on a Buhler
experimental mill.
protein = flour protein content as %
ash = flour ash content (%)
Mixograph time = time to maximum dough development, 10 gram flour
sample, National Manufacturing Mixograph
Mixograph tolerance = resistance to overmixing; 0-7 scale; 0 = no
resistance, 7 = maximum resistance; a measure of dough strength
Bread score - four variables 100 gram "pup" loaf test:
Loaf volume = volume (cc) determined by rape seed displacement
EXTN = loaf external characteristics, 0-12, 0 = unacceptable,
12 = excellent
GRAIN = internal loaf appearance (grain), 0-12, 0 =
unacceptable, 12 = excellent
TEXT = loaf internal texture (response to touch), 0 =
unacceptable, 12 = excellent
BRO - amount of potassium bromate added to the bake formula (%)
ABS - loaf absorption (%); amount of water added to loaf for
optimal dough development
BAKE MIXTIME - time in minutes to peak dough development, Hobart
Mixer.
These variables are divided into two separate files, one about flour
and dough properties and the second about bake performance.
