This study was aimed to determine the effects of different doses of gamma radiation (200, 300, 400 and 500 Gy) on some agricultural properties of M2 generation of Tarm-92 barley variety. The research was conducted in 2016-2017 vegetation period under Isparta conditions. Total 10 plots were taken in the study as control (non-irradiated), 200, 200 A, 300, 300 A, 400, 400 A, 400 A (C.B.) 500 and 500 A gray doses. The plots were fertilized with 10 kg/da nitrogen and 6 kg/da phosphorus (P2O5). During the study the data on plant height, spike length, number of grain per spike and weight of grain per spike were collected. Results showed that average plant height was 72.10 cm in the control and ranged from 55.19 to 70.22 cm in M2 generation. Spike length ranged from 7.43 to 9.13 cm in M2 generation and was 8.71 cm in the control plants. The number of seed per spike was 23.49 in control, whereas it ranged from 20.36 to 23.42 in M2 generation. The seed weight per spike was 2.73 g in control and ranged from 1.25 to 2.46 g in M2 generation. While gamma radiation reduced plant height, number of seed per spike, weight of seed per spike it increased spike length compared to control plants in Tarm-92 barley variety. The results indicated that 300 and 400 Gy applications produced more variations in terms of examined agricultural characteristic.
