[Characteristic of the univalent behavior in a series of monosomic lines of wheat Milturum 553 cultivar in the second meiotic division of microsporocytes].

The investigations fulfilled resulted in defining the character of the univalent behavior of each chromosome of the wheat cultivar Milturum 553 in the second meiotic division of the microsporocytes. General regularities of the hemizygous state of chromosomes in realisation of mechanisms of the changes of pole orientation and disjunction of chromatids to the opposite sides has been revealed.
