BULLETIN 1175, U. S. DEPARTMENT OF AGRICULTURE. 
which originated in Oklahoma, probably resulted from chance 
hybridization between a sorgo and one of the kafirs. Dwarf hegari 
was obtained as an importation from the Sudan region of Africa, 
evidently from the same region from which feterita was obtained. 
Darso and Schrock appear to resemble the kafir group more than any 
other group of grain sorghums. However, darso has awned lemmas 
and its seed color is a dull reddish brown, different from any of the 
kafirs. Schrock sorghum, sometimes called Schrock kafir, is awnless, 
but its seed color is a yellowish brown, and the seeds have a very 
astringent flavor, thus differing from the kafirs. Dwarf hegari 
resembles feterita in the color of seed, but the seeds are much smaller 
than those of the milo-durra group. Since these three varieties 
differ in certain characters from the groups which they resemble 
most closely, they are considered separately. The experimental 
data obtained for these three sorghums are presented in Table 13, 
and typical heads are shown in Plate IV, Figure 1.
