INDUCED RECOMBINATIONS IN POTATO BREEDING ON DETERMINANTS CONTROLLED BY POLYGENES WITH NEGATIVE CORRELATION

E.A. Simakov, I.M. Yashina, S.I. Loginov

With the using of tubers of the 40 varieties and potato hybrids of native and foreign selection, more than 60 hybrid populations of different origin, 12 samples of pollen the authors have worked out in detail the scheme and the technique of induced by γ-rays recombinations on valueable quantitative determinants (starch, productivity, field resistance to late blight disease of potato, time of ripening), which are characterized by negative correlations. The prospects were considered for application of recombinational variability in realization of breeding programs of creation of new potato varieties.

Key words: potato, hybrid populations, quantitative characteristics, γ-irradiation, recombinations, induced variability, TR-hybrids.
