  In 
  1915 
  this 
  Wisconsin 
  White 
  Dent 
  and 
  Black 
  Mexican 
  Sweet 
  

   cross 
  was 
  grown 
  only 
  for 
  endosperm 
  color 
  in 
  the 
  attempt 
  to 
  isolate 
  

   a 
  pure 
  blue 
  race, 
  and 
  no 
  intermediates 
  between 
  sweet 
  and 
  starch 
  

  

  w 
  

  

  were 
  planted, 
  as 
  the 
  starchy 
  kernels 
  show 
  the 
  color 
  more 
  easily, 
  

   especially 
  in 
  variegated 
  kernels. 
  

  

  The 
  fourth 
  generation 
  of 
  these 
  intermediates 
  from 
  the 
  cross 
  of 
  

   Black

  In 
  this 
  year 
  an 
  out 
  cross 
  was 
  made 
  in 
  order 
  to 
  test 
  the 
  

   behavior 
  of 
  the 
  intermediate 
  condition 
  in 
  combinations 
  from 
  

   different 
  sources.
