  reduced 
  by 
  the 
  injurious 
  varietal 
  mark 
  of 
  la- 
  

   cunae 
  (Liickigkeit), 
  the 
  whole 
  harvest 
  will 
  rap- 
  

   idly 
  deteriorate 
  by 
  the 
  selection 
  of 
  the 
  largest 
  

   kernels 
  from 
  varieties 
  which 
  are 
  not 
  quite 
  free 
  

   from 
  this 
  hereditary 
  deficiency. 
  

  

  In 
  order 
  to 
  estimate 
  the 
  value 
  of 
  his 
  rye- 
  

   plants, 
  he 
  gathers 
  the 
  seed 
  of 
  each 
  one 
  separate- 
  

   ly 
  and 
  sows 
  them 
  in 
  rows. 
  Each 
  row 
  corre- 
  

   sponds 
  to 
  a 
  parent-plant 
  and 
  receives 
  200 
  or 
  150 
  

   seeds, 
  according 
  to 
  the 
  available 
  quantity. 
  In 
  

   this 
  way 
  from 
  700 
  to 
  800 
  parent-plants 
  are 
  

   tested 
  yearly. 
  Each 
  row 
  is 
  harvested 
  sepa- 
  

   rately. 
  The 
  number 
  of 
  plants 
  gives 
  the 
  aver- 
  

   age 
  measure 
  of 
  resistance 
  to 
  frost, 
  this 
  

   being 
  the 
  only 
  important 
  cause 
  of 
  loss. 
  Then 
  

   the 
  yield 
  in 
  grain 
  and 
  straw 
  is 
  determined 
  

   and 
  calculated, 
  and 
  other 
  qualities 
  are 
  taken 
  

   into 
  consideration. 
  Finally 
  one 
  or 
  more 
  groups 
  

   stand 
  prominent 
  above 
  all 
  others 
  and 
  are 
  chosen 
  

   for 
  the 
  continuation 
  of 
  the 
  race. 
  All 
  other 
  

   groups 
  are 
  wholly 
  excluded 
  from 
  the 
  " 
  elite,' 
  

   but 
  among 
  them 
  the 
  best 
  groups 
  and 
  the 
  very 
  

   best 
  individuals 
  from 
  lesser 
  groups 
  are 
  consid- 
  

   ered 
  adequate 
  for 
  further 
  cultivation, 
  in 
  order 
  

   to 
  produce 
  the 
  commercial 
  product 
  of 
  the 
  race. 
  

   As 
  a 
  matter 
  of 
  fact 
  the 
  rye 
  of 
  Von 
  Lochow 
  is 
  

   now 
  one 
  of 
  the 
  best 
  varieties, 
  and 
  even 
  sur- 
  

   passes 
  the 
  celebrated 
  variety 
  of 
  Schlanstedtu 
  It 
  

   was 
  only 
  after 
  obtaining 
  proof 
  of 
  the 
  validity
