Jb. Ohm et al., SINGLE-KERNEL CHARACTERISTICS OF HARD WINTER WHEATS IN RELATION TO MILLING AND BAKING QUALITY, Cereal chemistry, 75(1), 1998, pp. 156-161
To investigate relationships of wheat single kernel (SK) characteristi
cs with end-use properties, we used 12 hard winter wheat cultivars har
vested at six regions in Kansas in 1993. Significant positive correlat
ions occurred among wheat hardness parameters including near-infrared
reflectance hardness score, SK hardness index (SK-HI), and SK peak for
ce (SK-PF) obtained by the Single Kernel Characterization System (SKCS
). The SKCS characteristics also were significantly correlated to conv
entional wheat quality parameters such as test weight, kernel density,
and kernel sizing. Flour yields were significantly correlated with SK
-PE SK-HI, and SK weight (SK-WT), suggesting the usefulness of SKCS in
evaluating milling quality. The negative correlation of milling score
with the standard deviation of SK-HI and SK-PF indicated that uniform
ity of SK hardness is desirable for good milling performance. However,
bread loaf volumes had significant negative correlations with SK diam
eter and SK-WT, mainly due to the inverse relationship between wheat p
rotein contents and kernel weights or sizes. Loaf volume regression va
lues, the changes in loaf volumes per one percentage point of flour pr
otein, also had significant negative correlations with SK-HI, SK-PF, a
nd SK-WT.
