The trustworthy correlation have been established between electronegativeness of nuclei and displaying of economically-valuable characteristics, which have the selection from splitting populations. Interspecific hybrids and selections from the splitting populationsdiffered with the univalent formation and chromosome assotiations, lowering of chiasma frequency. Prolongation of life of separating species or interspecies hybrids led to the prolongation of sterility. One-and two-fold gamethophyte selection led to the unanimous ripening and increasing of the general fruit mass on the plant. Lines, which had been received by the way of gamete selection, dry matters content, as well as sugar and acid content didn't become worse. It has been established the influence of gamma-treatment of seeds F1 on the percent of crossing-over at the integration of the results of identification of marker genes, quantitative characteristics in generation of low-adapted hybrids. One patent has been received.
