VARIETIES OF WHEAT

less wheats for dry upland. The variety which the Ohio 

 Station especially recommends for lowland is bearded, while 

 the two highest yielding varieties upon upland soil in nine 

 years' test are beardless. Some bearded varieties, however, 

 have also yielded nearly as well upon upland soil. Red grains 

 command the highest price because of their superior milling 

 qualities. 



94. Desirable Qualities. — The three characteristics which de- 

 termine the eight groups above are external and in themselves 

 are not essential, although they may be 

 correlated with essential qualities. Nils- 

 son holds that the purely botanical char- 

 acters have correlated with them such 

 valuable economic ones that too much 

 stress cannot be laid upon the value of 

 a pure botanical variet}\^ Some of the 

 qualities which it is desirable to obtain 

 in wheat are : 



(i) High yield. 



(2) Hardness and density of grain. 



(3) For some purposes and within 

 certain limits high gluten content of 

 superior qualit}% 



(4) Early maturit}^ (at least for some 

 sections.) 



(5) Resistance to drought. 



(6) Resistance to rusts. 



(7) Resistance to Hessian fly. 



(8) Stiffness of straw. 



Some of these qualities are interdependent, as for example 

 high yield and resistance to drought, rusts or Hessian fly, and 

 some are probably antagonistic, as high yield and high gluten 

 content.
