MORPHO-PHYSIOLOGICAL AND MOLECULAR GENETIC FEATURES OF TRITICUM AESTIVUM L. XEROMORPHITY

The article presents the results of years of research to determine the morpho-physiological and molecular genetic features kseromorfic cultivars and lines Triticum aestivum L. Research drought resistance of plants to the juvenile stage of germination caryopsides for sucrose solutions at different osmotic pressure and manifestation of morphological characters in the field, and genes drought DREB 1 resistance revealed a high level of polymorphism initial samples of wheat soft winter. Such genotypes as noblewoman, Dvorianka, Zoriana Nosivska, Л 41, Л 34-95, КС 21 have high drought tolerance and is looking to grow in the area of the central Forest-steppe of Ukraine periodically unstable wetting, characterized by frequent arid autumn and spring and summer.
