The effect of different doses of gamma rays and fast neutrons on the plant fertility and frequency of cytogenetic delay in the meiotic cells of barley after seed treatment was investigated. The increase in the fast neutron dose (0.05 to 8 krad) caused a lineary increase in frequency of semisterile plants. No considerable influence of the gamma dose level on the frequency of semisterile plants was observed. The number of cytogenetically damaged cells at prophase-metaphase 1 reached 9.1 to 19.9%, and 0.2 to 2.9% were reached at anaphase 1. A very high variability between the plants in the frequency of cytogenetically damaged meiotic cells was observed. In general, fast neutrons induced a relatively high frequency of large chromosome translocations. (auth)
