Blackhull kafir and White durra. It was discarded after the season 

 of 1912. No. 198 was a field hybrid, supposedly between Blackhull 

 kafir and WTaite durra, which occurred at the Channing Field Station 

 in 1906. Among the various forms appearing in the second genera- 

 tion were many that seemed very promising. They appeared to 

 combine the desirable earhness and low stature of the durra with 

 head and seed characters more like those of kafir. Selections of 

 these were made, and a number of them have been continued until 

 the present time.
