The inheritance of certain Quantitative Characters in Tobacco. I2I 
F, generations. Of these thirteen selections, two show about the 
same variability as the parents, four are intermediate in variability 
between the parents and Fy, three show about the same variation as 
the F, generation, and four show a slightly larger variability than the 
F, generation. Thus the coefficient of variability in F, ranged from 
6.44 + . 27 in (403 x 401)—1—2 to 10.84 +- . 39 in (403 >< 401)—1I—13. 
It is of interest to note that of the two types which were as 
uniform as the parents, that both were of intermediate value, as 
compared with the parents for leaf number, one giving a mean for 
leaf number of 22.5-+.09 and the other giving a mean of 23.9 + . 08 
leaves. 
The means of the F3 generations were of different values, ranging 
from 20.4-++ . 08 in No. (403 x 401)—2—1 to 26.3-++ . 20 in selection 
No. (403 =< 401)—1—8.
