Certain varieties, such as Minnesota 13 and Northwestern Dent, in 

 some cases have been in the best class and at other times have given 

 poorer results. This may indicate a narrower range of adaptation or 

 less adaptability than that possessed by the varieties which have 

 more often given good results, or it may indicate variability in the 

 seed used. 



A few varieties, such as U. S. Selection 160 and Amber Flint, have 

 failed to give good results in any of the tests in which they have been 

 included. This can not be attributed to poor seed, as that used 

 germ i n sited well smd produced good yields in the localities where the 

 d was grown. The conclusion seems justified that the poor per- 

 formance of these varieties was due to lack of adaptation to the con- 

 ditions of the tests.
