Rezumat

The present paper describes the stages of new genome synthesis – n-19, 2n=38 in the basis of the distant hybrid, sterile – DRX-55 (2n = 39), which contains in somatic set for everyone complete haploid set – n-19, 2n=38 from V. rotundifolia Michx., and V. vinifera L., respectively. By performing backcrossing, fi rstly in “in situ”, after in “ex situ” conditions, was eliminated the 39th odd chromosome from the nucleus (karyotype), and distant autofertile hybrids was obtained.
