Material Used 



All the work was done in & greenhouse under con- 

 trolled conditions. The temperature was regulated for 

 the best growth of cereals and water was added when needed. 

 It was necessary at times to fumigate for aphids. 



The plants used, as stated above, were from pure 

 lines of the wheats and emmer. The particular wheats 

 used in the crosses were: (1) Red Hussar; (2) Pride of 

 Genesee; (3) Jones Paris Pride; and (4) Early Arcadian. 

 The crosses were made reciprocally so far as the material 

 permitted. The period of flowering varied somewhat, mak- 

 ing it impossible at times to get the desired pollen for 

 some crosses. 



Table I gives the description of winter emmer and 

 the various wheats used in the crosses.
