摘要
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.
