27764. Andropogon sorghum (L.) Brot. Sorgo. 



From Scott City, Kans. Purchased from Mr. J. K. Freed. Received April, 1910. 



' ' Mr. Freed states that he has grown this variety for three or four years, but its origin is 

 unknown to him. He finds it ten days earlier than ordinary Amber sorgo, but he plants 

 a little more seed to the acre. In seed yield it outyields ordinary Amber fully 50 per 

 cent. The following description is by Mr. Carleton R. Ball: 



"'Stalk slender, 5^ to 6 feet tall; butts one-half inch to 1 inch in diameter; inter- 

 nodes long and slender; leaves 8 to 10; panicles well exserted, pyramidal to open 

 oblong — the pyramidal rather sparse, the oblong more dense; rachis continuous; 

 spikelets obovate; glumes straw colored, smooth to hairy; seeds rather obovate, pure 

 white.' 



"Mr. Ball further suggests that this may be identical with the variety cultivated 

 many years ago under the name of ' White Seeded or White India.'" (C. V. Piper.)
