Color of Kernel: This is determined in the same way as the color of the shell by comparing with a standard color scale, and the step of the scale whose color most nearly matches the color of the kernel being examined gives the figure to be awarded.
Proportion of Kernel: This is the ratio of the weight of the kernels of five average nuts to the entire weight of such average nuts. After this has been determined a comparison with the table below which was made up after an examination of the proportion of kernel of a large number of nuts, the number of points to be awarded is readily determined. If we take for example the Lutz black walnuts again we find the weight of five average nuts 132.0 grams and the weight of the kernels of these nuts 32.5 grams which gives for the proportion of kernel 24.0% which would be awarded 8 points.
