Overview
Durum wheat may be damaged by the effects of fungal disease. Discolorations on the kernel surface can result in lowered quality and increased cost of milled or processed products.
This in turn may adversely affect the purchase price of the grain. On a per kernel basis, the SPY determines the percent of disease and/or discoloration (D&D) on the kernel surface and reports
the damage (0-100%).
Durum Wheat D&D Results
The image at left contains a mixture of sound and damaged kernels. When the measurement is taken, red ovelays are applied to the whole kernel and white overlays indicate areas of surface damage.
Touching kernels are excluded from the measurement and therefore do not have any colored overlays.
D&D% for each kernels is determined and the results are grouped in 10% increments.
Since kernels with varying amounts of D&D are similar in weight (density), the y-axis value (% kernels) is equal to % weight of kernels.
The 10-bar graph shows the percent of kernels in each D&D% increment. At a glance, 80% of kernels have less than 30% damage. A 2-bar graph can also be displayed.
