  Harper: 
  Inheritance 
  of 
  sugar 
  

  

  as 
  Correns 
  has 
  done 
  we 
  have 
  a 
  ratio 
  per 
  four 
  of 
  2.93 
  starchy: 
  1.06 
  

  

  sweet.

  the 
  intermediates 
  are 
  classed 
  with 
  the 
  starchy 
  kernels 
  though 
  the 
  

   basis 
  of 
  their 
  selection 
  was 
  that 
  they 
  were 
  somewhat 
  wrinkled. 
  

   As 
  noted 
  above 
  we 
  can 
  also 
  distinguish 
  here 
  an 
  intermediate 
  in 
  

   the 
  starchy 
  kernels 
  between 
  dent 
  and 
  flint. 
  In 
  these 
  so-called 
  

   dimpled 
  dent 
  kernels 
  the 
  opaque 
  whiteness 
  and 
  large 
  wrinkled 
  

   depression 
  of 
  the 
  tip 
  of 
  the 
  dent 
  kernel 
  is 
  much 
  reduced. 
  They 
  

   shade 
  over 
  into 
  typical 
  dents 
  on 
  the 
  one 
  hand 
  and 
  typical 
  flints 
  on 
  

   the 
  other, 
  and 
  the 
  classification 
  is 
  not 
  always 
  easy 
  to 
  make. 
  

   I 
  have 
  not 
  attempted 
  to 
  separate 
  them 
  here 
  but 
  have 
  done 
  so 
  in 
  

   connection 
  with 
  the 
  ears 
  photographed 
  from 
  later 
  generations. 
  

  

  Kernels 
  from 
  four 
  of 
  these 
  Fg 
  ears, 
  129 
  a, 
  129 
  c, 
  130 
  a, 
  and 
  130 
  J, 
  

   were 
  grown 
  and 
  selfed 
  in 
  the 
  next 
  (F3) 
  generation 
  (1914). 
  The 
  

   kernels 
  were 
  selected 
  with 
  reference 
  both 
  to 
  the 
  inheritance 
  of 
  the 
  

   sweet 
  and 
  starchy 
  characters 
  and 
  the 
  aleurone 
  color. 
  I 
  shall 
  

   consider 
  here 
  only 
  the 
  results 
  with 
  the 
  sweet 
  and 
  starchy 
  characters 
  

   leaving 
  the 
  data 
  as 
  to 
  the 
  inheritance 
  of 
  aleurone 
  color 
  for 
  a 
  later 
  

   report. 
  I 
  will 
  take 
  up 
  first 
  the 
  results 
  obtained 
  from 
  selected 
  

   intermediate 
  kernels. 
  

  

  Ear 
  130 
  d, 
  showing 
  a 
  fair 
  number 
  of 
  intermediate 
  kernels, 
  

   was 
  selected 
  as 
  the 
  parent 
  for 
  the 
  next 
  generation 
  of 
  intermediates. 
  

   The 
  thirteen 
  white 
  intermediate 
  kernels 
  were 
  planted 
  and 
  six 
  

   ears 
  were 
  obtained 
  from 
  this 
  lot 
  in 
  1914, 
  which 
  ranged 
  from 
  one 
  

   (164 
  a) 
  which 
  had 
  almost 
  all 
  its 
  kernels 
  typical 
  sweets 
  to 
  another 
  

   (164/) 
  which 
  had 
  a 
  large 
  proportion 
  of 
  dimpled 
  dent 
  and 
  more 
  

   typical 
  dent 
  kernels, 
  though 
  the 
  photograph 
  Is 
  hardly 
  adequate 
  to 
  

   distinguish 
  the 
  latter 
  from 
  the 
  dimpled 
  type, 
  especially 
  in 
  the 
  

   rows 
  in 
  which 
  the 
  kernels 
  are 
  seen 
  directly 
  in 
  end 
  view. 
  I 
  have 
  

   taken 
  this 
  F3 
  series 
  as 
  illustrating 
  as 
  fully 
  as 
  possible 
  the 
  facts 
  

   regarding 
  these 
  intermediates 
  and 
  have 
  had 
  them 
  photographed 
  

   and 
  reproduced 
  life 
  size 
  so 
  that 
  the 
  degree 
  and 
  character 
  of 
  the 
  

   fluctuations 
  can 
  be 
  studied 
  as 
  they 
  appear 
  in 
  the 
  originals. 
  This 
  

   seemed 
  preferable 
  to 
  giving 
  a 
  larger 
  number 
  of 
  less 
  perfect 
  illus- 
  

   trations. 
  The 
  series 
  is 
  shown 
  in 
  the 
  photographs 
  and 
  the 
  classi- 
  

   fication 
  of 
  the 
  kernels 
  Is 
  given 
  in 
  Table 
  II, 
  section 
  i,A. 
  A 
  dark 
  

   intermediate 
  kernel 
  from 
  the 
  same 
  ear 
  (130 
  d) 
  gave 
  an 
  ear 
  of 
  all 
  

   sweet 
  kernels 
  (167 
  a) 
  like 
  164 
  a 
  of 
  the 
  white 
  series 
  and 
  is 
  included
