The inheritance of certain Quantitative Characters in Tobacco. IIg 
in 1912 while the remainder of the row was only moderately fertilized. 
The plants on the rich end grew very rankly and gave a range in 
variation from 22 to 32 leaves while the remainder of the row varied 
from 2I to 30 leaves. Another variety gave as high counts for leaf 
number when the plants were grown in 4 inch pots as in the open 
field under favorable conditions however, it is possible that the 
Sumatra variety is more susceptible to unfavorable conditions than 
some other types. The mather is discussed at this point as the 
Fig. 2. 401, Broadleaf. Averages about 19 leaves per plant. 
Coefficient of variability (8.28-++ .32) of 403—ıI—ı is higher than 
should be obtained in an inbred line under favorable conditions. 
Taking these points into consideration this Table shows the follo- 
wing facts: The F, generation is intermediate for leaf number, the 
Sumatra parent for rg1o giving a mean production of 28.2 + .08 
leaves; the Broadleaf, 19.2-+.05; and the F, generation 23.6 + . 07. 
The variability of the F, generation and the parents was about 
the same. The Coefficient of Variability of the Broadleaf parent for
