چکیده [English]

An  investigation    was  carried   out  on    yield,    yield    components   and  some   agronomic   traits evaluation    of sunflower  cuJtivars,   as  Randomized    Complete  Block   Design  at 4 replications   in Khoy  as summer   second  cropping   in  Agriculture   Jihad   Research   Station  during  2003.    In  this  experiment    12 sunflower   varieties   including  4 commercial   hybrids,  I lysun-33,   Azargol,   Allstar,    Euroflor,  6 new Three Way Cross  hybrids,  RI03*  Fl/7,   Rl03*    Fl/2,   Rl03*  Fl/16,   R95*  Fl/26,   Rl03*  Fl/l,Rl03*     Fl/18,    and two   open-pollination      varieties,     Record   and   Armavirecki,      were   planted     in  Tir   eleventh     (2   July). Experimental     results   revealed    significant    difference   among   the  features  of   the  varieties   indicating remarkable  diversity   of the  varieties  traits  in summer  second cropping  and the possiblity  of choossing  the excellent  variety  among  them.   Among  experimental    varieties,  hybrid  Rl03*   Fl/7  with average  growing season  of 93 days,  and Record  variety  with average  growing   season  of  104.   5  days were early  and delay ripening  varieties   respectively.    New T.  W.  C.  hybrids  with  average  growing  season  of 93-96 days,  were early  ripening  than all  of the commercial   hybrids  except  for Allstar   hybrid.   This  hybrid  with 94 days of growing  season  had no significant   different   with  new hybrids.  Record  variety  enjoyed  remarkable  plant height   among  other  varieties    excluding   Euroflor  and  Allstar  varieties,    but  other  varieties  showed   no significant    difference  as regards  this feature.  The highest  tray diameter  was seen first in Hysun-33  hybrid, and then in Record  and Rl03*  Fl/26  hybrid.   Weighty  seeds with average  test weight  of 57.70  and 57.19 were  seen  in  Record  and  Hysun-33  varieties  and the greatest  number  of seeds  in tray were  also  seen  in aforesaid  varieties.   The highest seed yield  related  to Hysun-33  hybrid with average 4004 Kg/ha  but due to lowness  of oil percent  in this  hybrid  (41.16    %) Record  variety  with  oil yield of  1839   Kg/ha comes  first among  others  and  Hysun-33  hybrid  with  oil yield   1646   Kg/ha  comes  second.   Then  come  Azargol  and R95* Fl/26 hybrids  with respective  average  seed yield  of 3116,    2967 and oil  yield of  1515,  1347   Kg/ha as  far as  the  amount  of  this  feature  is concerned.   Studying  of correlation  yield  and yield   components showed   that  there  exists   a  positive   and  strong  correlation   between   seed  yield   and  test  weight.   The experiment  results showed  that due to the region's   conditions,  planting  of delay  ripening  varieties  such as Record  and  Hysun-33  on timely  and  prematurely  can  have  the  highest  seed  yield   and  oil yield.   But  if there  is   limitation    of  planting    season,   early   ripening  hybrids  such  as  R95*  Fl/26   and  R103*     Fl/18 without   having   significant    difference  in  terms  of seed  and oil yield   with  above  mentioned  varieties,  are suitable    for  cultivation    as  second  cropping   in  region.    Provision    of  new  hybrids  with  enjoy  of  early ripening,  high seed and oil yield,   can lead  to the expansion   of area or sunflower  planting  in  the region.
