Inheritance and Linkage of Allozymes in a Balkan Endemic, Pinus peuce Griseb

This article presents a study of isozyme variation in Pinus peuce Griseb., a Balkan endemic. Among the enzyme systems studied, five were monomorphic and eight were polymorphic in at least one locus. The segregation analysis of the polymorphic loci were consistent with a Mendelian mode of inheritance. No significant deviation from the expected ratio was observed both at the individual and pooled segregation data levels. Segregation patterns were homogeneous across individuals. Two significant linkage groups were found in P. peuce: FEST-2:LAP-2 and 6PG-1:6PG-2, which correspond to the results obtained for other pine species.
