Summary
The inheritance of 6-phosphogluconate dehydrogenase (6PGD), malate dehydrogenase (MHD), aconitase (ACO), phosphoglucomutase (PGM), phosphoglucoisomerase (PGI), and glutamate-oxalacetate transaminase (GOT) polymorphic isozymes was studied in leaf extracts of nine hazelnut progenies using horizontal starch gel electrophoresis. Evidence of Mendelian inheritance was obtained for ten loci: 6-Pgd-2, Mdh-1, Aco-1, Aco-2, Pgm-1, Pgm-2, Pgm-3, Pgi-2, Pgi-3, and Got-2, which permitted the analysis of 28 alleles (2.8 per locus). The presence of null alleles was detected in Pgm-1 and Pgm-3. Joint segregation analysis of pairs of isozymes revealed four linkages: Mdh-1-Pgi-2, Aco-2-Pgm-2, Pgm-1-Pgm-3, and 6Pdg-2-Pgm-2.
