  Harper: 
  Inheritance 
  of 
  sugar 
  

  

  dents 
  and 
  two 
  lots 
  consisted 
  of 
  typical 
  sweet 
  kernels 
  (Nos. 
  165, 
  

   1 
  66), 
  The 
  dimpled 
  dent 
  lots 
  were 
  selected 
  to 
  represent 
  colors 
  

   from 
  dark 
  or 
  blackish 
  to 
  white 
  but 
  we 
  may 
  treat 
  them 
  as 
  one 
  series 
  

   with 
  reference 
  to 
  the 
  starch 
  sweet 
  characters. 
  Twenty-four 
  ears 
  

   and 
  nubbins 
  were 
  obtained 
  from 
  these 
  dimpled 
  dent 
  starchy 
  

   kernels 
  (Nos. 
  160-163) 
  of 
  which 
  twelve 
  showed 
  few 
  interme- 
  

   diates 
  and 
  almost 
  all 
  dent, 
  dimpled 
  dent, 
  and 
  flint 
  like 
  kernels 
  

   (extracted 
  dominants) 
  and 
  twelve 
  showed 
  conspicuously 
  dent, 
  

   dimpled 
  dent, 
  flint, 
  intermediate, 
  and 
  sweet 
  kernels 
  (F3 
  hybrids).

  The 
  proportion 
  of 
  intermediates 
  in 
  all 
  these 
  ears 
  as 
  will 
  be 
  seen 
  

   is 
  much 
  smaller 
  than 
  in 
  the 
  case 
  of 
  the 
  offspring 
  of 
  the 
  F2 
  kernels 
  

   selected 
  as 
  intermediates. 
  The 
  ears 
  of 
  this 
  class 
  of 
  F3 
  hybrids 
  as 
  

   shown 
  in 
  Table 
  II, 
  section 
  i, 
  B, 
  a, 
  give 
  1390 
  starchy 
  to 
  154 
  

   intermediates 
  to 
  369 
  sweet 
  kernels, 
  that 
  is 
  2.9 
  starchy 
  to 
  .32 
  

   intermediate 
  to 
  .76 
  sweet. 
  There 
  are 
  here 
  in 
  addition 
  to 
  the 
  ker- 
  

   nels 
  which 
  are 
  plainly 
  intermediate 
  some 
  others 
  which 
  approxi- 
  

   mate 
  starchy 
  kernels 
  on 
  the 
  one 
  hand 
  and 
  sweet 
  kernels 
  on 
  the 
  

   other. 
  The 
  classification 
  Is 
  diiBcult 
  In 
  some 
  cases 
  since 
  there 
  is 
  

   really 
  a 
  series 
  from 
  starchy 
  to 
  sweet. 
  I 
  have 
  put 
  in 
  the 
  class 
  of 
  

   intermediates 
  only 
  those 
  that 
  were 
  plainly 
  from 
  their 
  form 
  and 
  

   degree 
  of 
  translucency 
  neither 
  typical 
  starchy 
  nor 
  typical 
  sweet 
  

   kernels. 
  Here 
  as 
  in 
  other 
  cases 
  it 
  would 
  be 
  possible 
  to 
  make 
  more 
  

   than 
  one 
  class 
  of 
  intermediates
