ABSTRACT: This article focuses on the development of the
method for the genetic classification of agamospermous reproduction types in plants using
sugar beet as an example. The classification feasibility is ensured by the use
of isozymes as genetic markers allowing the identification of all three
phenotypic classes in the progeny of individual heterozygous diploid plant and
is based on different phenotypic class ratios in the progenies obtained by
meiotic and mitotic agamospermy. The data indicate that for studied forms of sugar beet meiotic agamospermy is the more
typical because 10 of 12 explored progenies were classified
as those which arisen under meiotic agamospermy and only 2 as arisen under mitotic agamospermy.
