Abstract
Three radiation doses (150, 200 and 250 J) were used using gamma rays and the effect of irradiation was studied on the apparent and productive characteristics of the barley crop. The study showed that the studied radiation doses showed the presence of significant differences in some productive characteristics of the barley crop in the fourth generation, especially in the number of grains in the spike and the length of the spike. For the barley crop and the beginning of the appearance of differences in the studied traits, as for the rest of the traits, the non-irradiated control (ACSAD 176) outperformed the radiation levels used in this experiment. When studying the percentage of germination, the gradient was normal, so the percentage of germination increased with the decrease in the radiation dose, and this happened in the characteristic of the average grain weight in the spike, the number of leaves, and the characteristic of plant length. The control was superior, followed by the dose (200 runs). Through the results, it was observed that the differences in the radiation doses appeared, and the beginning of some radiation levels exceeding the control (ACSAD 176), which is not irradiated, and waiting for the stability of this superiority in the coming years, as proven by future experiments.
