The high adaptivity of highly-adapted heterozygotes is confirmed by the method of functional space of indication modules. The total frequency of chiasma, frequency of interstitial chiasma raised for certain in the extreme conditions with the low-adapted hybrids. The stable lowering of chiasma frequency, including interstitial ones, and the number of non-typical bivalents in the direction from the free end to the base of anther was observed in low-adapted hybrids. The highly-adapted hybrids didn't have the displaying of this gradient. Raising of frequency of exchanging variations in unfavorable conditions took place only with low-adapted heterozygotes. The significant part of the violations was preserved on the on the stages of II division. The trustworthy correlation connection was established between plants characteristics in the conditions of heightened thickness and reducing water supply and the length of the vegetative season and commodity crop capacity, and also heightened variability as to the quantitative characteristics in the generation of low-adapted hybrids. One patent has been received. Product Description popup.authors Монтвід Павло Юрійович popup.nrat_date 2020-04-02 Close
