Residual effects of the influence of space factors on seed durum wheat seeds, through the third generation of oversouwing

The article presents the results of the study of plants of the third generation obtained from the sowing of the initial seeds of 5 varieties of durum wheat exhibited in space for 3 months in the Foton - M apparatus No. 4. The obtained results testify to the preservation in the third generation of the effect of cosmic conditions on two characteristics of plant productivity “CR” (the number of plants per 1m2), “HIear” (the harvest index of the ear). The different direction of the impact (positive, negative), noted for some traits in different years, can be explained by the interaction of changes (mutated structural or regulatory genes) in the genome with the conditions that formed during the years of study.
