leading to this loss of sugar will be given in a later paper on the storage 
of sugar beets. 4 
Table V gives the correlation between sugar content of beets and loss of 
sugar in grams during storage. 
Table V .—Correlation between sugar content of beet in grains and the loss of sugar 
during storage 
The value of the coefficient is 0.476 ±0.018, which indicates a practi¬ 
cal certainty of correlation. The table shows in a general way the fallacy 
of testing sugar beets after storage and explains how a breeder’s lines 
selected from such tests may continue to fall in sugar content with 
succeeding generations. 
Table VI gives the correlation between the percentage of sugar in the 
beet at harvest and the loss of sugar in grams during storage. The 
value for r = 0.366 ±0.020.
