SWEET CORN 



sort has impressed that parent's peculiarity 

 ■of color upon the grain of the immediate 

 cross. On the other hand, there has likely 

 been as much mixing of the white upon 

 the yellow, but it does not show in the 

 yellow ears and they look pure. This is 

 because the yellow color is dominant, and 

 the white consequently hidden or recessive. 

 It is easier to see how yellow can exclude 

 the appearance of white than that a starchy 

 grain impresses through its pollen the factor 

 of starch-bearing upon the cross. 



Now, to return to the block of corn, it 

 is seen that if the stock is a colorless sweet 

 sort, one breeder may be a yellow sweet, 

 and the cross may be separated out with 

 safety, provided no other yellow sweet kind 

 is used as a breeder. 



In the same way, another cross may be 

 secured upon the same block of white sweet 

 stock plants by using a sweet black sort; 

 for in this case any grain that is a cross 

 between these two will be a dark sweet 

 grain, and may be separated by planting 

 them under isolation the next season.
