Abstract

This study was conducted at the Experimental Field of the Department of Field Crops, Faculty of Agriculture, University of Ankara between the years 2004-2006 in order to determine the effects of various ethephon doses on yield and yield components of Triticale cultivars. Tatlicak 97, Karma 2000, Melez 2001 and Presto cultivars of Triticale were used in this study and 0, 150, 300, 450 and 600 g/ha ethephon doses were applied at the beginning of heading. Both the results of two years were separetely evaluated in the study. According to the results of the research; significant differences were determined with the application of various ethephon doses on four triticale cultivars in regard to grain yield and yield components. The greatest values were generally obtained at 450 g/ha ethephon dose in grain yield and yield components. More increase in ethephon doses caused decrease the values of grain yield and yield components. Melez 2001 and Tatlicak 97 cultivars have generally the highest values in the all traits.
