摘要
Genetic variability in Turkish chestnut (Castanea sativa Mill.) was measured by means of horizontal starch gel electrophoresis of 16 isoenzymatic systems in 13 populations. The results were compared with existing data on Italian chestnut populations. Thirty-one out of 43 alleles showed significant heterogeneity in frequency among Turkish populations. Most enzymatic polymorphisms show a gradual or sharp difference between Eastern and Western Turkish populations. Western Turkish demes seem genetically to be more closely related to Italian populations than to Eastern demes. These results are discussed in the light of historical and palinological records of the domestrication of this species.
