were planted at the same time as the Valencia seed used in the rotation 
experiment, and the resulting plants were all given the same treatment 
as regards cultivation. Notes were taken throughout the season and 
the results are given in Tables II and III.

From the data it is seen that Valencia peanuts from Station seed and 
from Government seed are about equally susceptible to 5 . Rolfsii . 
Tennessee Red peanuts are considerably more resistant than Valencia. 
Spanish peanuts are slightly less susceptible than Valencia. Hog Goober 
is practically immune to 5 . Rolfsii. Virginia Bunch is more resistant 
than Valencia. Virginia Runner is practically immune^ African is 
practically immune.

The results obtained on plot 2 and presented in Table III substantiate 
those of plot i, and indicate that the African, Virginia Runner, Hog 
Goober, Virginia Bunch, Tennessee Red, and Spanish varieties are 
resistant to S. Rolfsii about in the order named, and all are more resist¬ 
ant than Valencia.
