Abstract
The enzyme variability among 17 apricot cultivars including nine Greek cultivars was examined electrophoretically.
Both starch and acrylamide gels were used and stained for 20 enzyme systems, 15 of which were found polymorphic.
The polymorphism in 18 zones of activity (PRX-1, EST-1, ACP-2, LAP-1, GOT-1, FDH-1, ADH-1, SOD-1, PGD-2, MDH-1, MDH-2, PGM-1, PGM-2, ME-2, GDH-1, ACO-1, ACO-2 and DIA-2) was recorded.
On the basis of this polymorphism, thirteen cultivars were characterized uniquely by their isoenzyme phenotypes.
Cultivars Bebecou and its putative mutation Pella were identical as well as cultivars Hasiotiko and Koliopoulou.
Both starch and acrylamide gels were used and stained for 20 enzyme systems, 15 of which were found polymorphic.
The polymorphism in 18 zones of activity (PRX-1, EST-1, ACP-2, LAP-1, GOT-1, FDH-1, ADH-1, SOD-1, PGD-2, MDH-1, MDH-2, PGM-1, PGM-2, ME-2, GDH-1, ACO-1, ACO-2 and DIA-2) was recorded.
On the basis of this polymorphism, thirteen cultivars were characterized uniquely by their isoenzyme phenotypes.
Cultivars Bebecou and its putative mutation Pella were identical as well as cultivars Hasiotiko and Koliopoulou.
Genetic studies in a family segregating for incompatibility reaction, showed that the activity in six zones is coded by equivalent number of genes named GOT-1, EST-1, SOD-1, PGM-1, DIA-2 and FDH-1. These isoenzymic genes could be useful as markers for agronomic characters including the sexual incompatibility.
