- Abstract
This study was conducted in The Central Research Institute for Field Crops in Ankara in 2010. The aim of this study was to determine the most efficient dose of gamma irradiation for the mutation breeding program of milk thistle (Silybum marianum (L.) Gaertn.). In the research, some characteristics of M1 plants of milk thistle obtained by irradiation of the seeds with different doses of gama rays (0, 200, 300, 400 and 500 Gy) were studied. The result of study showed that emergence rate (%), seedling height, seedling root length, seedling fresh weight and seedling dry weight were decreased by the application of increasing doses of gama irradiation. According to the results of this research, mean values of characters were varied between 34.3-80.0 % in emergence rate, 4.76-6.08 cm in seedling root length (cm), 6.09-11.00 cm in seedling height, 577.66-1164.00 mg in seedling fresh weight and 38.33-82.33 mg in seedling dry weight. From the results of the study, it was concluded that the most efficient doses of gamma rays for mutation breeding program of milk thistle (Silybum marianum (L.) Gaertn.) could be 200-400Gy.
