Fic. 5. Sorghum Hybrid (Feterita & Sumac Sorgo). At the extreme 
left is a stalk of Feterita, an excellent a sorghum, with large white 
kernels, whose average height 1s 4 to 5 feet; it is very resistant to covered 
kernel smut. The second stalk from the ae is Sumac Sorgo or “ Red 
op,” a sweet sorghum with small and dark reddish brown kernels. It 
averages 514 to 6% feet in height; it is very susceptible to covered kernel 
smut. The third stalk from the left is the first generation hybrid (F:) 
between Feterita and Sumac Sorgo. It is taller than either parent, the 
panicle is larger, and the kernels are intermediate in size and color. 
T 
he remaining twenty plants are the offspring of Number 3, or the 
second generation hybrid (I). These are arranged to show the great 
variation in height, the size and shape of the head, and the size and color of 
the grain. Their descendants show various combinations of the characters 
of Feterita and Sumac Sorgo such as height, pithy or juicy stem, white or 
colored and large or small kernels, and resistance or susceptibility to 
covered kernel smut.
