Comparative investigаtion of the physiological and biochemical properties of Beta vulgaris L. haploid lines

Abstract

The aim of the work was to study the isoenzyme spectra of several lines of haploid regenerants of sugar beet in comparison with the parent forms in order to identify the most interesting ones for further selection. The donor material was the MS-form (malesterile form), haploid lines derived from it, as well as the fertile donor and its haploid lines.It was shown that the spectra of two enzymes − isocitrate dehydrogenase and malic enzyme are polymorphic, and the enzyme 6-phosphogluconate dehydrogenase is monomorphic and cannot be used in further selection.
