PLATE 4 
A. —Dwarf plant from the second generation of the dwarf-brachytic hybrid, showing 
the type of tassel, sturdy stalk, and short, wide leaves. 
B. —Brachytic, dwarf, and brachytic-dwarf maize plants. Brachytic at right, 
dwarf at left, and the double recessive in center. The brachytic and dwarf plants 
are sibs from the second generation of the dwarf-brachytic hybrid, while the double 
recessive plant is from the third generation of this cross, having been obtained in a 
progeny from a self-pollinated F 2 brachytic plant which proved to be heterozygous 
for dwarf. No such sharp distinction as is indicated in this picture was found in the 
second generation between dwarf and the double recessive. It is apparent that the 
double' recessive form of this combination is much larger than the double recessive 
anther ear dwarf figured by the Emersons.
