 study was made. He reports in the same paper a cross of 

 Red Fife V/heat and Polish Wheat which gave many types in 

 Pg, one of which was very similar to spelt. He thinks 

 that few if any of the types can be regarded as fixed in 

 the third generation. Another cross^^ of Polish and 

 common wheats gave many types hut very few of P, seed grew 



to maturity.

B. C. Buffum secured what he called a most remark- 

 able series of mules and monstrosities from a supposed mute- 

 ting type of wheat and a supposed mutating emmer. Inter- 

 mediate types were^absent while almost every known type 

 heretofore produced was present as well as decidedly new 

 types of grain. Types which seemed to indicate reversion 

 were numerous, one of which was the single-seeded spikelet 

 of the monococcum type; another gave the dicoccum type; and 

 another, true Triticum spelta. Buffum thinks that the results 

 indicate a common origin for all forms of wheat. 



M.A. Carleton ■'■^ states that emmer readily crosses v;ith 

 wheat and that the department at Washington, as well as ex- 

 periment stations, have used spring emmer for the purpose 

 of adding rust resistance to ordinary wheat. V/inter emmer 

 should have even a greater value in this phase of wheat im- 

 provement .

 Carleton gives the possible lines of improvement 



by the wheat emmer cross as : (1) Resistance to fungous at- 

 tacks, (E) drought resistance, (3) increased fertility of 

 the head, (4) non- shattering, (5) stiffness of straw.
