The objective of this study was to develop IMI (Imidazolinone) group herbicide resistant rice varieties to control weedy rice (red rice) and the weeds gained resistance against conventional rice herbicides in rice fields. For this, the thirteen cross combinations were done with an IMI resistant rice variety at Trakya Agricultural Research Institute in 2007. Using these crosses, some breeding activities carried out. As a results of these studies promising IMI resistant lines were developed and they were tested in the observation nurseries and the yield trials in 2012 and 2013. Also, a backcross program started in 2008, eight backcross combinations were obtained, seven of them reached to BC6 and one to BC4 at the end of 2013. As a preliminary results, some promising IMI resistant rice lines selected in 2013, and they are being tested in the regional trials and demonstration experiment under farmer’s conditions in 2014. A few of them will be nominated for registration as commercial varieties in the end of 2014 crop season
