There were significant differences in the structural indicators of productivity between the positive control and resistant forms in plant height, number of grains per ear and the main plant, grain weight from the main spike and grain plants. At the R1 plants have established doubling the level of free proline compared to the control. The testing of seed R1 plants confirmed the resistance of this forms, thet suggesting genetic determined of resistance to stress factors. Is shown cytological stability of R2 plant seed generation. The resistance to water deficite in the obtaining form may be associated with genetic variation that affects the regulatory genes, in particular Dreb 1. It has been shown that fragments of 596 and 717 bp - the products of amplification Dreb A1 and Dreb B1 genes, there are only in resistant to water deficit regenerants and absent in unresistance forms.
