Time for Testing Mother Beets

The results here shown indicate that the difference in the percentage 
of sugar before and after storage is very irregular. In looking over this 
table one does not seem to find any relation whatsoever between the 
fall test and the difference in the percentage of sugar before and after 
storage. It is likewise difficult to see any relation between this difference 
and the spring test for any one beet. One could not derive the fall 
test of any beet from the spring test, and as a result, the breeder is at a 
loss to select from his spring-test data those beets that will test high at 
harvest time. It would therefore be quite impossible to breed up a 
strain of beets which would test high at harvest by making selections 
from spring tests. 
In order to determine what relation exists between the percentage of 
sugar originally contained in the beet and the percentage which it loses 
during storage, correlation tables were made. Table II gives the correla¬ 
tion as determined from Friedl’s analysis. 
Table; II .—Correlation between percentage of sugar in beet and loss in percentage of sugar 
during storage 
The results shown in this table indicate a correlation value of 0.272 
±0.0338 between the percentage of sugar originally found in the beet 
and the decrease in percentage during storage. 
The results from the analytical data of Table I are given in the follow¬ 
ing table:
