Notes:
Genetic markers are most useful in plant breeding but so far only a few morphological and isozyme markers are known in Beta vulgaris. In this paper, the isozyme systems aconitase (AGO), NADH-:dihydrolipoamiddehydrogenase (DIA), esterase (EST), fructose-1,6-bisphosphatase (FDP), and hexokinase (HK) were genetically analysed. Isoelectric focussing (IEF), vertical polyacrylamide gel electrophoresis (PAGE) and starch gel electrophoresis (SGE) were used to separate the isozymes. A total of eight loci could be identified. The allelic forms of Aco-1, Dia-1, Est-1, Est-5 and Hk-1 are active monomers. The gene products of Est-3 and Fdp-2 are active as dimers. Est-2 also showed allelic forms without activity; null-alleles.
