Seeds of lettuce Lactuca sativa L. were irradiated with neutrons with an average energy of 1.6 MeV at a dose of 10 Gy. Irradiation was performed at the end of the limiting time for preserving the conditioned freshness of seeds. The seeds were germinated in a hypomagnetic chamber at a magnetic induction of 1 ×10^3, 1.4 × 10^2, and 2 × 10^1 nT, which corresponded to the reduction of the geomagnetic field by 5 × 10^1, 3.6 × 10^2 , and up to 2.5 × 10^3 times, as well as at laboratory conditions (5 × 10^1 μT). After germinating at hypomagnetic conditions, the percentage of cells with chromosomal aberrations in the root meristem of seed-lings grown from irradiated seeds increased at all the considered values of the reduced geomagnetic field. The synergistic effect of factors according to the criterion of cells with chromosomal aberrations and the antagonistic interaction according to the average number of dividing cells at the stages of ana-telophase was noted.
