About thirty other species and varieties were tested in single rows 

 in 1908, but none of these proved to be of any special value for this 

 region except S. P. I. No. 20694. Seed of this number was obtained 

 by Professor Hansen, at Khokand, Russian Turkestan, in 1906, when 

 acting as agricultural explorer for the Department of Agriculture. 

 A quantity of the seed was planted in a selection row at Belief ourche 

 in 1908. Two plants in this row matured seed and were saved. 

 Since the plants were identical, so far as could be seen, the seed from 

 the two was mixed and planted in a progeny row in 1909. The 

 selection is of good forage type, but the panicle is open and the seed 

 shatters readily.

BREEDING METHODS. 



The methods used in the millet-breeding nursery were much the 

 same as in the alfalfa nursery. In 1908 the seed of each of the 

 varieties, Kursk, Common, German, Hungarian, and Siberian, was 

 planted in hills 8 inches apart, in rows 42 inches apart (PI. Ill, fig. 1). 

 The seedlings were thinned to single plants in a hill. Selections of 

 the superior individual plants were made and the seed planted in 

 single rows 8 rods long, in 1909 (PL III, fig. 2). 



RESULTS OP THE WORK. 



The table following gives the record of yields and other data 

 concerning the individual plant selections made in 1908 the progeny 

 of which gave the largest yield in 1909 :
