Abstract
The inheritance of 6-phosphogluconate dehydrogenase (6PGD), malate deh ydrogenase (MHD), aconitase (ACO), phosphoglucomutase (PGM), phosphogl ucoisomerase (PGI), and glutamate-oxalacetate transaminase (GOT) polym orphic isozymes was studied in leaf extracts of nine hazelnut progenie s using horizontal starch gel electrophoresis. Evidence of Mendelian i nheritance was obtained for ten loci: 6-Pgd-2, Mdh-1, Aco-1, Aco-2, Pg m-1, Pgm-2, Pgm-3, Pgi-2, Pgi-3, and Got-2, which permitted the analys is of 28 alleles (2.8 per locus). The presence of null alleles was det ected in Pgm-1 and Pgm-3. Joint segregation analysis of pairs of isozy mes revealed four linkages: Mdh-1-Pgi-2, Aco-2-Pgm-2, Pgm-1-Pgm-3, and 6Pdg-2-Pgm-2.
