From Table 2 it is noted that these pure lines averaged to 

 yield at the rate of from 132.8 bushels to 81.3 bushels per acre. 

 It will be understood that the 34 lines given in the table are 

 selected from the 79 which were grown. As a rule the discarded 

 lines yielded less than those given in the table. However, in 

 instances where high yielding lines showed undesirable charac- 

 ters these were also discarded.

It is of interest to note the distribution of these pure lines 

 among the different parent varieties. From Table 1 it is noted 

 that there were 188 pure lines grown in garden rows. These 

 188 pure lines represent 18 differently named varieties. The 

 34 lines given in Table 2 represent eight different commercial 

 varieties. It will further be noted from Table 2 that certain
