respectively. Blackhull and Red selections tie for fifth place with 

 average yields of 13.9 bushels. 



The breeding of the early variety, Sunrise, and the early and dwarf 

 variety, Dawn, is seen to be justified by the outstanding favorable 

 results.

The Kaoliang Group. 



The kaohangs are grain-producing varieties of sorghum from 

 China and Manchuria. The most important varieties have been 

 separated by a simple key (p. 17). The group has been quite fully 

 described by the senior writer ^ in a previous pubhcation. 



The kaohangs are very diverse in height, earUness, and produc- 

 tiveness. So far, only one variety, the Manchu, has become com- 

 mercially important in the United States. All have dry pithy stems, 

 and many of them are fairly early, presumably with rather low water 

 requirements. However, those which are early enough to be valu- 

 able have never been able to compete in yield with Dwarf milo, 

 milo. Sunrise kafir, etc., except at the extreme northern edge of the 

 sorghum belt, as in South Dakota. The varieties grown are present- 

 ed in three subgroups, White, BlackhuU, and Brown, in Tables 

 XXXI to XXXVI, inclusive.
