Electrophoretic analysis of genetic variability in the apple

B. L. Bournival, S. S. Korban

Research output: Contribution to journalArticlepeer-review


Starch gel electrophoresis using leaf tissue was employed to study 9 enzyme systems of the apple (Malus × domestica Borkh.); these were CAT, EST, G6PDH, MDH, SKDH, PGI, PGM, GOT and PER. Four enzyme systems (PGI, PGM, GOT and PER) exhibited some polymorphism and 3 loci, one each from PGM, GOT and PER enzyme systems, were identified and genetically analyzed using progeny tests from controlled crosses. PGM-1 had 2 alleles, Fast (F) and Slow (S), and was functional as a monomer; GOT-2 had 3 alleles, Fast (F), Medium (M) and Slow (S), and was active as a dimer; PER-2 had 5 alleles, a, b, c, d and e.
